Hey everyone, Good afternoon. Less aware for another one minute. To talk about whoever comes in late today, I'm going to miss the greater presentation. All right. So first of all, I want to let you know that I think last week, most of you took the opportunity of the special examiner and the Friday examiner to fill in the police reduction points. So you all did a great job. I received an e-mail feedback and also questions during the presentation, and I still encourage participation. I know if someone's already rich, poor seminars, maximum, I still encourage you to participate into any future seminars and a presentation to continue to learn. Okay, so for today, we're going to have a lightening top. Four minutes at top. So after three minutes, you should think about either ramp up or I will ask you to leave the stage when the time is up. Okay, so today I compiled everything together. I know some of you have animations, family, you just have one slice. Either way. I compile them together. I'll try to do as best I can. Okay. So we're going to follow the order I posted on Canvas and see your name comes in and make sure you stand up, come to the front or inlet. You are you'll get prepared to go to the front. Okay, So I will pull up your presentation slide here. But you can use that one slide to do your presentation. And this afternoon at about three tarnish, you should receive an invitation to join our Google Form. Okay? That form is shared between you and me. So everything you're typing there is confidential. I will steal your all of your effort to do the evaluation because I believe if I've only person to do that, I may be biased. So just a little bit instruction. On the form you'll receive. All of you should have received more form like this. It has two sub sub, sub sheet. Ignore the second one, data value, a validation. That's just a whole program, so we don't have to touch. You should look at the evaluation sub sheet. And in here, I put everyone's name together in a sequence so everyone go into present. There's three-minute or four minute talk in this order. And you're going to evaluate them based on five different categories. For each category, there are five different skills. So you can choose whatever that applies. And in here, what do you have to do is fill in the area. So this blank area for you either to type in the gray or you can use a Jada. There will be a one-to-five. There's no 14, 15, there are no 3.5. So make sure whatever we type in fall into this category. And 5, 12, 5 scales. So I also program that sheet in here in case you have a typo. So for example, if you're typing eight, you will see a red box come up. We should remind you there's error. You have to fix that. Okay, too, because it will affect the ranking. And if you type in something like bureau, is it below the scale? So it will also pop up as direct color. So a guy that would have something between one and fly, you'll receive a green box. So that's CLI that means good entry. Okay. After that, I'll be attaching this information. You will see here. Within the program, it'll automatically provide to you the latest top five presentations. So which means that you may have various degrees strict rule for the first presentation. But as Hongo on, you will feel like you want to make adjustment because you'll want to provide fair and Eva evaluations across different speakers. So you can always come back and fix something to make sure the grading a balanced. Okay? So there's the top. If I box it will have the type. So they will automatically fill in based on whatever you provide it so far. Okay. Any questions regarding how to use the Google Sheet? Now? Okay. I got my God. She's like looking at a timer like honor, to see how we're doing on time. Yeah. There was a hand over there. Just like, Okay, great. So no matter what, I cannot tell you if this speaker is on time or not, the timer, well, and this lecture is recorded if I make a wrong decision and you can always remind me because our Turkheimer will tell the truth. Okay. All right. So if everyone is clear about the evaluation, let's get started. So go ahead. Where is it? Where the Google form. Whereas a Google form. You should receive an email from me. Ask you to collaborate on a Google Sheet. Do have that. Okay. Anyone else in this room that does not receive argumentation? Okay, we're good. All right. So our first speaker will be the lone pair on there. Let me switch to the camera. He was only one color today. Okay. No matter what, I'm going to turn our work and see you. I don't think the camera works right now. I have another class in here and it doesn't work as well. Yeah. Okay. No. All right. So it's always still can go this way. We'll see, we'll have a slide of view of your presentation here. Okay. You may step backward a little bit. We conquer area. Better out bed, okay? Yeah. Okay. Let's do that. But I could use my home screen. I will pull up the slides for you. Okay. All right. Okay. Are you ready? Yes. Okay. Last got to ruin today. My talk very familiar with my husband. I thought today is the CO2 flux in the northern Gulf of Mexico. And we also want to understand it is controlling mechanisms. Before my talk, I wanted to then I will just call and response that I bought in essence, this phone horizontally to television side. And both are so high. Yeah. The first initial what we want to do antibody assay CO2 flux in the northern Gulf of Mexico. So we use steel. We can observe visual data connecting phone, the colonnade communities that cause those observations to picture that we have to show the philosophy now another Gulf of Mexico and we also all the other atmospheric CO2 and that we spit. We have one set slides that I'll results shows that this first week that in that right-hand side, inside of our panel, I'll read that shows that the entire coastal region, hold on golf and hold pulling up on this quantities of steel to seek ways the flux at a force me to read yellow point to say that mol Kelvin times just to test our result is sensitive to the dataset from the truth or not because we chose that, sever, their staff Protoss and those that needs to reanalyze data set. So we want to see whether the children of these two, the asset he's sensitive or no. So we tested the other will be again the atmospheric CO2 data and all of that it shows them and low-income a mascot me, just see what the CIF. So we can be very confident to say that the conclusion is right. And then we want to understand the controlling mechanisms of the CO2 for us. In the moment alcohol miscible, or in other words, why in a moment, GF a match curricula super thick. So first of all, I guess see that when I started seeing these handlebars, that here is the velocity and is much larger than other seasons. So they place due to the gestures, but velocity will be, She's, which can be calculated by the second, the second power they'll always be. And because the winter with these higher than how the seasons. So this contributes most to those. We've had steel, zinc in our study area. The other thing is the we've got promoter on the recent nutshell, all that Mississippi and a sharp layer river. If on the phone the phone knows, we do our calculation. And this is the annulus copy of connotation in the, in the open. And the PCO2 result shows that they have a very cool leak aswell. And this is the annual average. And if we use the sum or average, which when biological removal process the strongest and this R-square when it comes to 0.7. So badly we can make a conclusion that the Tanaka from SQL, the secret. And this concludes rabies the party by macho. We speed and atmospheric and pieces you what a p-chart. Go to Data Products and Kenny them. The CO2 plus log off on this coffee is controlled by the asymmetric see progress, you know, with this code and the loss that you've GCO to whatever on the Ariba. True? So yes, this might talk any questions. Do we have a question or comment on that? Now? I'm forgetting now. They can take the two this time, about 30 seconds that's done In your input. No worry. After everyone's presentation, we will have another term called time for you to complete the form as well. Hey, next. Take your time. No rush. Okay. Everyone else? Now we come back to us and Grant will be our next speaker. Right? Yeah. So I don't have slides, but you'll have a timer. Oh, yeah. Okay. I'm Grant and I study penguins in the western Antarctic Peninsula as these are a deli and Gentoo penguins which I'm studying. And the main question I'm always trying to think about is, how are these penguins deciding where they're going to go for it? You know, what, what decisions are they making during their foraging trips? And it's really important for us to know this because one, they had this huge energetic, energetic costs that they're incurring by going out on these trips, by trying to feed their chicks and all that. So it's really important that we know how they're deciding where to go. And we can learn a lot about other organisms and these penguins if we study this so we can know how other organisms are foraging and we can also understand how these organisms are going to react better to a changing prey environment in the future. So to do this, I'm studying just one aspect of foraging behavior and that's trip memory. So are these penguins trying to remember places that they go before? Are they trying to avoid areas of low prey density, which is kind of what we think about in an optimal foraging, optimum foraging theory. So, yeah, so these penguins are theoretically going to be going towards areas of high prey density and avoiding areas of low prey density. And to look at this, I put, or we put GPS tags on our penguins to this idea of foraging locations. And then I also want to look at the depth data from depth of quarters, get an idea of foraging success. So in theory, we should see if these penguins are trying to remember where they're going. Forging location, you should be very similar if foraging success is very high. So that is kind of the relationship we're looking for when I go through the data. And when I did that, when I calculate foraging success from the depth data and foraging locations from the horizontal data. What we found is there's actually not really any kind of correlation between those two factors, which is really weird. We would expect there to be a high correlation between prey density and the likelihood that a animal would return to that location. Now, there's a few reasons this could be happening, why they could just not really care about high density prey patches. And it could just be that the penguins can't remember. They don't have any ability to remember where prey is. Or I think there's a few more likely situations. One of them being just that they know kind of in general where to go. They know. Okay. Over this Palmer canyons feature, which is where they are, this is a sign of those big sloshing around of krill and tray. And they know just in this general area they can go out and probably find food in this area. Another possibility is that they're keying on to some kind of environmental variable that we haven't. Exactly figured out yet. This could the temperature of the water, this could be so entity though different. You'd have parcels of the water which they know that krill really like to be in. So they can key onto that, which it doesn't. It may or may not be in the same location as previous times. So that's kind of what we're looking at right now in the future. We're definitely going to try and look at those those kind of places and those kind of water features to see if that is kind of what the clues are. But right now does not seem like they really try to remember. High prey density. That's my phone. 30 seconds. Goes up. Your turn. Go ahead. Sorry. Yep. Okay. We've got a restart. Your Gaga. So the primary focus of my research is the Beaufort beluga whale. And so this isn't migratory species normally spend half the year and the Bering Sea and Alaska, and the other half of the year in the Beaufort Sea in Canada. And so it's likely that they have two diets, but we're not really sure. And so my first research question is to actually look at their foraging movements and behavior to try and figure out what they're eating. And then once we know this, I'd like to look at how climate change is impacting their foraging movement. And so you're probably wondering, like, why is this even important? And so Beaufort beluga whales are actually essential species to a lot of indigenous communities in both Alaska and Canada. And so there's that reason. But their apex predators in the environments they live in. And so if there are impacts to these organisms, it's going to have cascading effects throughout that, you'd guess it sounds as though the first thing I need to do in order to even testis these questions is to get samples. So I plan to get current pray samples from both ocean basins, from noaa. And then I'll get frozen whale samples over the past 30 years. So get samples from the 1990s, the early 2000s and 2010s, and hopefully 2020. And I'll get those from fisheries ocean Canada, self to look at what they're eating. Essentially plan to take the appraised samples and the current but Lucas samples, put them in a machine which is going to tell me the specific isotopes are working poor. So in regarding diet, I'm looking at carbon-13, nitrogen-15, and mercury CO2. So carbon 13 tells us a time integrated diet of a sample. Nitrogen-15 tells us the trophic level of that sample. And then Mercury Joe team provides more dietary information on that sample. So using these three isotopes, I can kind of figure out like what the food was there and look like and what the whales and their prey could possibly eat it. And that's answered my second question as to how climate change would be impacting HIV diet. I put in. So I'll look at carbon-13 and mercury to O2 again, but in the frozen blue samples over time. And so if there are changes in their diet, this should be reflected in changes in the isotope values over time. However, I'm also going to be looking at mercury one. I do not. So mercury 199 reflects the light penetration within the ocean. So if there are high mercury when I'm nine values, that means there's highway penetration in the ocean that they're in, which means that there is an increase in ice now as a result of climate change. So theoretically, if the changes in the carbon-13 and mercury to two values which represent diet are changing throughout time and those changes are coinciding with increases and mercury 199, which reflects essentially climate change, then it's possible that the bot will get dy is being impacted as a result of climate change. So overall, that is what I plan to do. Habit started my research yet, but that's the plan. Our next speaker is ready. They can eat it though. So my habit is my accumulation. I'll be fast. And that our bay. And what he fast and as far as parent calling floral alkyl substances. And so what they are is these are compounds and they're all DNA. And so they're coming into the bay from industry effluent. So anything that being pushed out. Of a factory or because they're water soluble, they're washing ox different products that we use that half the class on them. For example, you're not stuck where your jackets, anything that water proof or not likely has left the fast component to it. Especially pipeline, pipelines, a big one. And so because they're water soluble, they're flowing from these places into the bay. And so we're looking at the different accumulation and what effects they're having. Because we have strong evidence that they are causing cancer, that they're disrupting endocrine systems in both humans and then the animals in the day. So in order to look at how they're accumulating, to look at I'm sorry, I want to go destruction, hook them. Just let me back my bad. To look at the structure of RPI fast organisms here before. Sorry, I'm so nervous anyway. To look at are actually different. They make that PFOA and Polly floral often an acid. And it's a carbon skeleton with an OH group on the end. Some of them again and then print or flaw off to know itself and eight, and we've got a sulfonic acid group on the edge of that. So the length of the chain and the different functional groups are what give each P FAS its different components, and each component has a different bioaccumulation. And so what bioaccumulation is? The total mouth, a compound accumulating inside an organism. So that includes what they eat and what they're getting from the water that they're swimming in. This enough if you're a fish, you're slipping, That's a lot. And this is important for our regulation because we need to know how they're getting to the finish. Because we can't regulate the amount of contrast in, especially in regulated in the water because the fissure in the water we can control with inside a fish. So in order to do that, I'm collecting a lot of organisms from the day. And I'm looking at bioaccumulation is by looking at that final magnification and the bottom concentration, that's the food and the water coming into the organisms. So this is an example of one of the equations that I'm using, bio concentration factor. That's the amount coming in through the water. We look at the concentration in the organism as opposed to the concentration in the water it's zooming in. So I don't have data for the organisms yet, but I feel time for Theta water. I have affiliate example that I've working. So what I'm seeing so far, just orienting you to my little graph that I've got concentration and different spots. As you move towards the ocean, concentration goes down, but it is higher and perform that in PFOS. Pfoa left there to different amounts. And so we can kind of see a green as you go through the ocean. But we're also seeing that these different functional groups on the end are making a big difference. And so my research is looking at more at bats then reflected in the species of the bay. And then what we can do to kind of remediate that in the day. Awesome time they have to. All right, Next, humming to himself the comfortably ovens and push. Those. Are hello. Welcome to my talk here. So let's look at the whole group homes for the Arctic states and a high latitude system up off the coast of Canada by Greenland. And basically what it boils down to is I'm looking at where are they, What are they there? What are they doing while they are there? And the main goal of this is to look at how can we use this information to then control how these gates are caught as bycatch in a local fishery, as well as how client changes in the high Arctic ecosystem. Which is very crucial because this is actually an ecosystem that experience there's pretty significant ice coverage which influences the actual ecosystem dynamics. So knowing how the species there are affected as well as the environment itself is very crucial to our understanding of how the Arctic systems will change in the future. So the way that this is all, there were a series of acoustic telemetry where we get presence versus absence data, which basically says, Hey, we're here at this time, at this location. That's all we get. Which has a sounds very simple, but it's actually very light depth on what we can do because it tells us a lot about when they're, when they're not. And then we can estimate Charles B, we can estimate what they could've been doing area and based on environmental factors like temperature, chlorophyll, and stuff like that. Then using this data, we then can estimate a total range of argc, which we then can usefully bycatch mitigation as well as international. Integration into policy didn't want. And then one of the biggest things that this will allow us to do is to basically develop these current utilization distributions, otherwise known as Katie's, which basically outline hotspots of proactivity usage, but a space where we can say, okay, this gay occupied and 95 percent of its detections that occupied, say, 30 square kilometers, but 50 percent it occupied, or 50 percent of its detections. Whereas in a like, say, 50 percent, 50 kilometer area. And then once we open up those between this case, we can say, okay, a majority of states are found. Is this smaller region maybe about ten kilometers. We recommend you don't fish there during these times of the year. So that way you don't unintentionally kill these gates while you're fishing for the Greenland. How that is also a big species. My area. And then through the KUB is we then will increase our general knowledge of Baffin Bay ecology, which is very crucial because a lot of marine mammals like narwhal, seals, whales, and other things like even like the Greenland shark up here in this area, which is very useful to understanding a complex ecosystem. And as I mentioned before, it this area is actually covered in ice for a good portion of a year. So knowing how something like escape, which represents kinda like it, species, how they're being affected by it will then in turn sell such a child. If they're being affected by this, like their presence is decreasing over the years. Is that because the production of what primary producers and their prey items are decreasing? Or is it that for some reason the predators of the artist gates are then increasing. So we can kind of see how the food web and dynamics are shifting a bit. That'll be very crucial to advising the actual Canadian government as well as the sort of ecological institutions in place, those who were very interested in this region for that exact purpose. That was basically funded. Clearly or do you want speaker closer to the microphone? We call these are yeah. Thanks. Good afternoon, everyone. So today we'll talk to you about the movement of the tiger tracks ventricle in Egypt and more recently around two ions that I called Maria and type in 1080. Yeah. So finish painting guys will get it. It basically the middle of the Pacific Ocean, in the mid south Pacific Ocean. And then you can find his tank traps, which is a very large truck species, one of the largest. And it's known to be a migratory species, so it moves a lot. So why is it important to study trucks movement? It's the case for several reasons. First, it as they move a lot and they have a specific goal in mind because they stand. So they regulate the lower tropical else because they are hitting on. And also connect the different ecosystems by moving from one to another. So their movement is very important. It's also very important to identify places where they can impact business, what would improve the management and stuff like that. So understanding the movement, the formula we are not able to follow Is, is there very important so that they are sharks. We don't experience refresh, bring it up into four is movement. We would sum with an acoustic telemetry. So we put transmitter in sharp, emits a signal regularly, and then it receives all around us. And the receivers will listen for the transmitter that are around. And so you're able to know that discharge was displaced. Is there is that that's very valuable data. And our results are really, really cool. And we find that the net use the islands evenly. So there are places where it go. Basically we don't go. And most typically we think due to very specific areas where the gold, so you can say, okay, this is the two sharps hotspots, hotspots around THE, for example, that when you look at it closer, if we give a closer look to what's going on, we see that they do not use these two places the same way. So when does it mean to not use narrators in way? Is non-degenerate conference and at the same time are the same habits there. There's one of the places where they come a day and at night, mostly at the middle, so I'm running time of the night. Did you let go every day so it might be there today, not tomorrow, maybe the next day. But the other station, which is not so far. This is why it's surprising. The shocks only going between them and four, five-year exclusively at this time. So try to know why they come here at a specific time and waste not the case for the other species. So this station where they come at specific time is characterized by a lot of sharp dragging activity. So basically, dining center, faith to attract the sharks and the tourists consider shocked when they die. And they do that. Of course, during the day. Ten AM and phobia. So this is the exact time when the shocks come. So we could wonder, sharks come there only because of that, which is probably the case studies. They can be addressed directly to the sprawling what we see. So what legal to go further and do new research on this being to address the specific question is specific, is visually now that sharp feeling is forbidden, so there's no fitting anymore. So it would be interesting to see if tanker trucks are still coming between ten AM and four PM when the feeding is not occurring anymore, which is probably not the case, but I can assure you that until we get some new session on me. Thank you. Are you ready? Yeah. Hello. My name is Emily and I want to talk to you about this beautiful picture of Love Creek in southern Delaware. This looks like a great day that I took this picture on the boat in June of 2021. But what is not being shown here is all the bad bacteria than water that reduced from things that we do, such as eating, drinking, agricultural waste and also just static waste. And when I say waste, I mean fecal bacteria and these bacteria, somebody from our guts, from other animal guts. The issue is that it's just destroying our quality of water, so our quality of life dimensions and the ways that we can look at this, practice this by looking at these communities compared to our own communities and our values. So what I do is use microbes from the pool of a lot of different sources for us and then the water to see what's in it. And then also instead of antisemitism, taking a natural parameters to get all the DNA to see what is there so that you didn't use it in source tractor to find out what's actually polluting our waters as title, whose pubis it anyway. So I've art Started, can show you right now from the small results is that we see that there's a lot of input from the human source and also sediment. And what this is doing is showing us that there's a natural flux of micro is being back introduced into the water bath dynamics, but then also by our waste, our human waste. And what we can do with this further in the future is use it to determine, are we gonna do about this? How are we going to take our waste and actually fix it up so that we're not polluting our water is more than we already are. And then we can also take into account all these other animals and see that they're not really polluting the waters as much as we think. So we're wasting a lot of money with things that have been done, such as trying to keep the goose away from the water because they prove when they come to hydrate bell for even trying to keep the pay the rabbit population slope when there's no reason for us to do that because we see that they're not even polluting the water as much as anything else. So if you want to know more about any of the results that I'd have, please come talk to me later this week and my Twitter is linked at the bottom. If B underscores which you have leftover money, That's it. That's all I got. Hey, you're making it even better results and work that I've done as, partly as a master student, hardly 0 once I graduated from my mass unless program of my university, Delaware, That's wanted to discuss is a paper we published in 2020. And it looks at the ebb and flow of protons in a coastal system as it were a part of vulnerability called the virtual estuary. And Buddhist said vacation is the long-term decrease in pH in coastal and open ocean systems. But the problem with acidification is pH is measured on a log scale. It's not really usable for looking at change between different systems and using it for modeling purposes. So what this work was really trying to do was student was to demonstrate and all application for suffocation in terms of proton concentration with both as additional discussion on using proton concentration the future for additional research. So at this research, we were trying to look at rates of exchange and direction to change the profile of the P2P systems. And then we have two end members here, as you can see in this, in this here. We have, then we have it. So it's a tidally force system. So over here as you see, we have Delaware Bay, it's high or low proton concentration, H plus over here, as I said, pH scale. So low pH equals high protons and vice versa for low pH equals high proton content. If so, we have Delaware Bay and then we have the estuary here that's run by a lot of mosque. So on the peptide or falling tied you have downstream flow from the estuary into the bay. And the way you measure pH here, the black cylinder is a kind of pH which we then calculate proton concentration from. And that on the flood tide of war. Incoming tide from the day to the estuary, you have water flowing from the Bay to the estuary into the mirror kill. And that also here we have the other end members have heard of cholesterol rate, which is 10, slightly low pH and high proton concentration. So the main issue I have with trying to walk at pH differences in how things affect, how it affects pH. One-on-one system affects the other is like say, peeps on a log scale so you know, something's affecting but how much you don't really know. So essentially if we did not use proton concentration, you would just monitor pH over here and pH over here. And you see this is really high. It doesn't vary a lot. That's really low and doesn't vary a lot. How does this, it goes on in the bay, affect the asteroid, has the estuary affect the bed? So what we did is we took our peak ligaments, medical sensors, and then we use a discharge measurement from the USGS that it's also right here with the sensor is being employed. And we essentially just multiply discharge sounds a flux, I mean discharge side of the concentration. It's very simple to get your flux. And then the problem, ill or problem we have is here it's entirely force system. So essentially you just have water going from a baby to the estuary, need flood time in the estuary into the bay on the peptides will just go cyclical like that. So in order to really get at what's going on with the phasing out, the shredding that and looking at subtotal controls things like windstorm events of stuff that is because changing histories of both pH and everything we're looking at. So once you do that, you're, you're left with something called the mean non-tonal flux or processes that are not total fluxes that are a lot less frequent, that are affecting homeless is either going on there or here. So essentially when you have a flux that's greater than 0, that's downstream flows, essentially you have protons coming from the estuary into the bed. And then if you have a less than 0 that's negative, that's upstream flow from the Bay into the estuary. So when you have downstream flow, the USSR acidified Bay and then when you have upstream flow, the story buffers the bay. And essentially mean flux for our work was always in the negative direction. So on long-term, there's a, there's a net flow of protons from the Bay. Okay. Okay. Good afternoon everyone out my reflection we into my topic, GitHub, Maginot, blue crabs, recreational fisheries and then Bay. And the reason why we're doing it, because they're narrowly kept positive, they pulled that detrimental impact to toy that economical. And I, to think they're not very good article and economical secretaries and I, they have been recently found to harvest and industry. So people are Shimon be conducting identify conducted we face to identify and remove about a thousand parts throughout the summer. And we will do this to the absense the impact of this on the tax rates and economic benefits of removing the pot to quantify what each habitat will provide for the harvest. This says that we believe our culture work because we will separate each site into separate habitat degradation areas. We will set cards on each area to conduct the research and our panel on this from the events. Virginia Marine Science who have actually conduct this and publish a research paper not too long bone the same topic, just in a different area. So we believe that our approach similar to the Earth, are we working out the reason why I research? We believe it will be stopped and beneficial. Again, it will be used to estimate species richness and diversity, as well as the impact that had been handed to them by the end of the ground under them as movement, what ties and stuff like that. We will look at. Another benefit of it will be like the economical benefit, toys harvesters, and the community itself in the area community, depending on what it is, I have recreational or so a lot of the areas overlooked in ISR around near parks said, Oh, the pensive their recreational areas or if they are public areas depending on over there for fishing. And we will do is to quantify the habitat benefit by creating indices of that species richness, total yields, economical yields. And that will give you much needed a bit of research. That's pretty much it. Actually, yeah, For the past and they seem to hinder. Another reason why it's important because that's deposit they seem to affect they kill, I'm out of bycatch, maybe I territory in diamond bags. And that's one of the main reasons why we are looking into the eye. So that's kind of that. How much are they not induce early 1970s crime against bycatch been in the part. That's where anyways, hopefully that's good to know. Speakers left. Yet. So harmful algal blooms are phenomena that are economically and ecologically devastating and they occur all over the world. It is not a localized problem. And in fact, if that actual harmful algal blooms worldwide are increasing in frequency and severity. It's like a mike over here is that ice will stand farther away from creating a frequency severity. And this is caused by anthropogenic impacts such as nutrient runoff and also by climate change and 70 percent of known toxic, harmful algal bloom calling species of algae belong to a taxonomic group called dinoflagellates. So dinoflagellates are actually especially predicted to benefit from increased CO2 concentrations in the ocean. So what are we gonna do about this as this problem will become Breyer time? So my research focuses on a bacterium pulse you and ELA species are IRR I want 60 that specifically poisons dinoflagellates. We know that it secretes a mixture of chemicals and we're interested my lap and how those chemicals affect the algae, but also what those chemicals on. So one of the first things that you would do intuitively to answer a question like this would just be to do an analysis to see what kind of chemicals are in there. And rather than being just one or two, or three, or even a dozen major components, we found that this poison is a mixture of hundreds, actually over thousands of chemicals. Said, narrowing that down to figure out which chemicals are actually important is having a daunting task. But we know from previous research and I love that amines are important and we chose three specific needs and interests future seeing cadaveric sperm again, because they are widely commercially available and sheep. And we are interested in quantifying the activities of those chemicals on the red tide dinoflagellates for any of rabbits. As I am using dose-response experiments to quantify the effects of those chemicals on peroneus brevis. They're basically looking at how much chemical is needed to invoke a particular response by the Alpha AGI, death or dying or morbidity. So the information that I get from doing these experiments will give us more insight into what types of chemicals are actually responsible for the effect that this bacterium has. And also whether or not using pure compound harmful womb, the Asian techniques that would be just using a compound instead of spreading bacteria. Whether or not that's a viable option for harmful algal bloom. So our speaker will be curly. Hello everybody, thank you for sticking around for the intercession. My name's Caroline and my research is about seeing how well we can use sharks as Ocean Observing craft forms. So what are ocean observing platforms? There's stuff that measures the features of the oceans that are important for Science and Management, like temperature or salinity, or what different current movements are doing. And historically we see this being done with at the equipment that's heavy and expensive and depends on the time of year to go. Think about a ship going into the Arctic to drop off some centers over the side. That's expensive. I can only go in the summer. Think about samplers like gliders. They're expensive and they occasionally break and are drifting emails, offers, speak. And so there's a lot of interest in bringing in animals, specifically chars, just because the tagging sensors that they need are cheap. And there's a lot of them and a lot of different habitats, which means everywhere they go or places we can get information. And so we start to think about this question of, well, what shark species are going to be good observer candidates are really looking for animals that are going to surface regularly and dive deep. Diving deep, because that means that they're going to go to the places we want to get information on servicing regularly. It has lot of these tags rely on satellite transmitters, which means that the tag has to get a connection at the surface to a satellite. And as we're gonna see, that's not always the case. So my work is done looking at satellite tag information or data for 14 species of pelagic sharks. And lots of breakdown here, folks in the top panel first, that's the maximum depth that each species has been recorded to achieve. The colors refers to the number of individuals that were tagged. And so say you're interested in studying a shallow-water phenomena. You're going to be interested in these guys on this side of the graph. Deeper automata as the other side. And so the bottom panel is telling us how well they're able to connect to the satellites. And that's determined by feature called location class. Sort of like a sliding scale for uncertainty of where the satellite, so the shark was going to be. All you need to know is that green is good, red is bad. So say you want to study species that dive to like a 150, 300 feet meters. I'm sorry, I was going to be your guys in the middle. And species that tend to have better location class distributions are more greens. Or a short film makers or salmon sharks are common to russia shirt and our blue sharks. And do applicable. So we know where they're going roughly. The other question is how reliably or the sampling. And so here we've got, on the y-axis is the total number of transmissions over the x-axis being our sins deployment for those top four species, or blues or crushers are salmons and RNA goes. And the red lines are sharks. The blue lines are just regular intervals. So say an animal a sampling once every six hours, you'd see a lining up with this blue line. And we actually see that are common dashes, shark, sam servicing more frequently than that. So why is this important? If your tag has a short battery life, you want to be able to program that to a realistic sampling interval and have the shark itself be servicing as often as you're willing to program your tags to be. So we also see that Bouchard, through sampling roughly between every six hours and every 12 hours. And our salmon sharks are first makers or surface sampling and a much less reliable, great amount of time. Ultimately, this comes down to what you want to study, the Keck. All right, very nice and very diverse presentation today, you can see that it is even more diverse than the 15-minute regular presentation. So I want to ask how many of you had experience about like lighting talk before, before this class. Have, oops, sorry. As we'll see. The light it's all going to experience was like very different. So it was a little shorter, a little weirder than this solves. So many minutes do have it was just too, too. Okay, are equivalent, we'll say equivalent. Okay. I see one hand up. The other is not ready? No. Anyone from the other campus? Yeah. Yeah. Okay. First of all, I already insert my evaluation. I'm look I'm looking forward to seeing yours. So first of all, I want to give an overall comment on today's liking taught. I think you'll all did a great job in highlighting your research for sure. So everyone, regardless of the length of your top, you'll highlight either your research. But one thing I want to remind you, you only have three minutes. Okay. You may just all the hallway walking with a program manager or the judge. So how to do that? You might want to reconsider that. Play up the importance of your research. There are about two or three students here did a farewell. Use more than 1 third of the time to highlight either researching, report it. Okay. Within any one time. Okay. Within the 30 minutes, it really hard to like to insert a science into other people's mind. Okay? Then if you can't do that, why don't you highlighted the importance of research, like some students here, even slow down mention of lies important to ecosystem. It's important to that of the ring system. Why is it important to the entire community? Because this is the overall question would have been waiting for addressing the answer. Okay. So overall plan for the three minutes. Talk wisely. It could be two minutes. So you want to spend 1 third of the time just to highlight the importance and major outcome if you are successful. So for example, if you're successful, you're going to change in the next-generation of observing platform. So we're May, maybe we're using more tradition, non-conventional way like this way. Now CCDs, just to give people or impression how big impact your research it will have. And also when you come into our master's, both of you very enthusiastic about the research results? Yellow. Okay? On the contrary, you can see that there are several students who did not really develop the research yet, but they did very well. They give you the logical ways to perform the research. Sometimes it's easier to follow than the details. Okay? Now I want to all of you step back. Even you have done the research already. You have you have done goes through that. Sorry, I 365 days to do that in the lab. Now you will have three minutes. You can speak with the details. Only highlight the most important parts of the result or the methods. Okay? That's almost like when you write a proposal, you want to highlight what is most important and what we're mostly saying, want to learn. And that's now may take half of the time. So then the rest of time you can highlight it impact. You can link your research to the other discipline or other community. Usually that's a way, sorry, minuss or spend. But again, could be totally different ways because you are going into a different program. You're going to different conference. There could be different ways to present. But for today, I think you have the first-time experience about showing your three minutes version of the research. You have done a great job and they're based on maybe some room for you went to improve. And we will leave that to the next a class for discussion. Okay? Alright, let's go back. Announcement. So we'll have Friday examiner this Friday, and it'll be our UDFs USGS at solitaire. So Dr. David, a lunch we'll be talking about the latest program in collaboration with New York City, dp on operating the drinking water quality in this area. And also something related to sea level change as well. And pre-shared data you can explore and evaluation of Latin talk due by the end of today. So you still have time to adjust your evaluation before submission. So after tonight, I'm going to pull this offline so there's no chance for you to modify anymore. Make sure you're typing everything by midnight. And also I want to and ask that. So we have an a great job for panel summary and all the fate of x. And now available. If you go to the homepage of Canvas, you can see they're starting at home here, showing you the link to the piano summary. Also, this link is e-mail authentication. Protect it, so it is confidential between you and me. Okay. And guidance for the next class. So next the class seems to our done all the presentation rehearsal and the lighting, the top. Then I want to reserve the next class for discussion. So we're going to discuss what's the difference between three minutes, 15 minutes, and 45 minutes presentations. I know now we don't have first-hand experience it for 45 minute presentation. Most of you have attended the seminar and special seminars in the past several months. So you may bring that as experience comparison to the other two categories. Okay? So what I would like you to do is submit one question for more questions. So using a Google Sheet I'm going to share later today to let me know. What's the most part you're curious about this topic. You'll, you'll may just be curious about how to do the slides because you can do 515, present 50 minutes presentation using 12 slides Was that has to go to 45 minutes. What other slides you can put again, okay? You may want to know more about before and after presentation, what you should do, like 50 mil position, usually out of the conference, everything is program. So well. While 45 minutes you were to occur during job talk and some not so alone work how Carol conversation, if you're curious about that part. So now your question, we're going to discuss together. So the Legal Eagle allows you to think on Friday, make sure you submit your question before midnight, Monday, next Monday, okay. So that I can have QCI Wednesday to particular materials and share with you. And also regarding your question, please do some research before you come to class. I know it's always good that you are curious. You ask a question, but I want you to do the research about the answer of your question. And then I will share some experience. Wrestle class and they share some experience as well. Okay. And to gain the participation during the discussion of next lecture, several classes she's up to okay. So if your quiet during the first half of lecture, make sure you can speak up in the second half, okay, everyone had to be part of the discussion. And also everything will be in Parser, Okay, Make sure you come to the classroom and we're going to do that discussion face-to-face. And after that next lecture, I'm going to showcase some examples for before and after, which we're going to do in the next couple next couple of weeks. So I'm not going to lobby. You'll give entire presentation again in front of class. You're going to record that and submit for me for my evaluation, okay. But you're going to have 10 minutes to showcase what supplies you want to improve. Or even with the same slide, how are we going to
