The obvious question is, “How?” We barely get by right now. We were forced to live off of our savings and house downpayment a long time ago. The first thought that came to my mind was a bake sale. Why not? Other people have done it. Eric was skeptical and laughed, thinking I was joking. I was dead serious. You don’t know if something will work until you try and regular channels aren’t working. We have to get creative to get what we want.

So I suggested my idea about CafePress again. He’s had an account set up there, but never did much with it. When I was brainstorming for ideas on how to make money to cover our bills if the PhD offer doesn’t come through, I thought of printing our leaf art onto T-shirts to sell. Eric read about other scientists who have turned to the online community for help and thought, “Well, maybe we CAN do it.” And so, Science Bake Sale was born.

Please go take a look and see if you like what we have so far. We have plans for more CafePress designs and some marine biology and ocean themed original artwork and dyed clothing that will go up on an Etsy Store as well. Our first goal is to buy a replacement scooter, so Eric is sure to be able to complete his research dives.

After working a bit from home, I got ready to bike in to campus and walked out the door at 10:40am for a 45 minute commute, taking the cyclocross route along the coast that I like best. I felt well rested and my legs were ticking over really well, but as I got down to Noank, which is about 5km in, I had a sinking feeling. Had I remembered my dive computer? A quick check of the panniers confirmed that I had not.

Longer, but more scenic commute to school

I decided I really wanted the computer, so I turned around and added an extra 15 minutes to the commute. Now I would, at best, be 10-15 minutes late. The rest of the commute was great, with a new personal best for the route, minus the false start. It was a bit late to see much wildlife on the route, but I did see several herons and one scrambling woodchuck.

Joe was waiting in the dive locker when I arrived 10 minutes late. The tanks were already filled, so as I verified the blend and fill of my tank, we talked about the amazing women’s world cup game from the day before. Before heading off to get some lunch, we went up to see our dive safety officer (DSO) who had just gotten back from vacation. While he was away we had several dives and on one of them I flooded one of the locker’s canister lights. I wanted to tell him in person and find out what needed to be done to get it fixed.

Unfortunately, it was not just any light. It was his favorite light from Salvo (now Light Monkey) with a custom made cable so it would fit his rebreather rig perfectly. Ouch.

WLIS MySound Data Buoy

After taking my ass-chewing for flooding the light, I called Light Monkey, who set up a repair for us. They told me they could turn the lights around in one day. No way we could get them back in time for the WLIS dive, but we should still have them back by the end of the week. I boxed up the flooded light and a second light with a shorter cable that also needed some routine attention. Dive lockers are notoriously hard on gear! After almost 3 hours we managed to get everything taken care of and the lights off to Florida with express service.

Finally, we could get back to the dive. Instead of our original noon start time, we crawled over the seawall by the dive locker (that’s a real joy in doubles, mind you!) and into the water at 3:04pm. It was a great dive too. Visibility in the cove was about 5′ and filamentous algae covered the bottom. But as soon as we got out of the shallows, vis opened up to maybe 10′ and the filamentous algae disappeared, revealing a thick carpet of macro algae and sea grasses. It seems to be an especially good year for the sea grasses and kelp, denser and much larger patches than I remember any year before.

Beach to beach swim - Dive Locker on right side, sail boat launch beach on left.

The fish count went great. We saw fluke (a.k.a. summer flounder) (Paralichthys dentatus), cunner (Tautogolabrus adspersus), grubby sculpin (Myoxocephalus aeneus) and tautog (Tautoga onitis), as well as blue crabs (Callinectes sapidus), spider crabs (Libinia emarginata), and three horseshoe crabs (Limulus polyphemus), including a very large male. There were many young of the year winter flounder (Pseudopleuronectes americanus), from a half an inch to 2 inches long.

As we were finishing our surface swim into the beach (too shallow to dive with the surge, too deep and rocky to walk), we noticed the DSO’s pickup truck parked right at the sea wall. As it was a bit late, we knew he was waiting for us. As we climbed up on the beach, he asked after the dive, what we saw etc., then casually asked who the lead diver was. Joe and I had never really settled who the lead diver was. He has ten times my experience, but I had suggested doing the dive, so I took the responsibility (knowing the other shoe was about to drop, most likely on my gluteus maximus). Sure enough, in all the confusion about the lights, I had forgotten to fill out the dive plan log on the marine operations bulletin board. We had fully briefed the DSO, but someone asked the marine operations manager if the divers off the Point were university divers. He didn’t know, but went down to the marine operations bulletin board to see. Ooops! Lesson learned and reinforced well.

Ass-chewings, by the way, do obey the laws of gravity, picking up momentum as they go downhill.

One of the things I have to keep coming back to is “What do I want to be when I grow up”

But that has never been a simple question. When I was young I wanted to be a scientist and an explorer. I was excited and my imagination ignited by archeology, marine biology and the space program. I devoured national geographic magazines, Wild Kingdom and Jaques Cousteau’s specials. I remember reading and re-reading the articles by Dr. Eugenie Scott on the amazing fish of the Red Sea and sharks in general. I remember reading about Dr. Sylvia Earle’s descent to 1250m in a hard suit and her Tektite mission. I know it may sound crazy, but one of the highlights of my brief science career so far was to dive on the Aquarius site as a science diver… the descendant of Tektite, it was, part way to an old dream come true – to live and work in an underwater habitat studying the seas for hours and hours at a time. One day I still hope to make that dream come true.

But my path took a strange turn and instead of going to Woods Hole or Scripts or Harbor Branch, I ended up in the Army working as an advanced communications specialist using, trouble shooting and fixing just about every type of communication technology in the Army, but specializing in satellite systems. It could be a challenging job, especially in remote combat deployments, but it really didn’t make me stretch. I spent my spare time reading and improving my animation skills as a form of entertainment. In Central America I learned to scuba dive and spent as much time on Roatan Island as I could, doing 3-4 dives a day. The more I dove, the more I needed to learn about the fish and invertebrates I was seeing. I subscribed to several diving magazines and bought every marine biology book my scuba instructor could get from the States. I invited my future wife to meet me in Roatan, unfortunately she declined.

After the army I worked in the computer industry in engineering and eventually web development until the bubble burst. When that happened I returned to school, studying computer systems and graphic design. Unfortunately returning to school also revealed that I had a memory issue. Tammy knew before, but I denied it of course. Unfortunately the tricks I had learned to use on the job, didn’t translate well to the academic environment. I struggled to find a new way of learning and studying, while my grades sank, eventually forcing me to admit defeat temporarily as I withdrew from school.

Fast forward to five years ago when I took advantage of an opportunity to again return to school. This time in Oceanography. I had since learned to deal with my memory issues with new strategies. I started slow, with only two classes, but soon took on a full course load completing the four year degree in three and a half years with a job, a family and still managed a 3.5 GPA. My old skills in electronics, optics, video production and web design all served me well working in labs and earning me opportunities to work with Remotely Operated Vehicles. At the end of undergraduate I knew I needed to take this further, I needed to revisit my old dream of being a scientist working in, on and under the ocean.

I was accepted to the graduate program and began learning more about sustainable fisheries and GIS than I thought was possible to learn (and yet I have still only learned a spall portion) . It has been a good run, but now it is almost over. I want to go on further, but I know I need a change in direction. My interests lay more with larval and juvenile marine organisms and their ecosystem roles (besides the stock answer I get from many: “as food” – too damn easy), or in the ecology of deep sea and mangroves and with invasive species in connection to any of the previous. I have at least a hundred questions banging around in my head, and I am loathe to even try to pick only one and say -> This is it.

One of my favorite fish of the mangroves is the juvenile sergeant major. Very cute, shy and nervous - darting constantly around the patch of mangrove they call home. Copyright E. Heupel

More than that there is the question of what good is a PhD, and is the cost too high to justify. I have put my family through a lot already. It has been financially very hard, and we have done without a lot. I have been fortunate that this program knows me, and knows the type of contribution I can make, and also understands that my family is the most important thing in my life. I will never be one of those scientists (or PhD students) so driven by the research that I sacrifice my family (which I have seem too much of in the past 5 years). Driven yes. If I had a spare $10,000 right now I would be on a plane to Belize to chase down one of my burning questions on invasive species and My Seascape of Fear (actually budgeted with no salary it a hair over 10,000). But I’m not going to throw my family under the bus to get there.

Which brings it once again back to what I want to do with the degree. I would like to be able to design and conduct my own research, which I would need a PhD for. I enjoy teaching small to medium size classes, as long as there is at least one or two kids turned on to learning. At a University or college a PhD is generally the ticket for admission to that. At community colleges, a PhD can be required, or a hinderance.

As for the most singlehandedly enjoyable thing I have done in the past 5 years – it would be the outreach efforts at Aquarius. Doing the science, putting on a live show, broadcasting it to kids in their classrooms and online – both doing science and helping to communicate it to a larger audience. That was for me a real rush. Many of the people involved in that team effort did not have PhD’s, but then again many did. I enjoyed the fact that we were communicating conservation, physics and biology directly and passionately to an audience eager to learn.

If I stopped right now, my ideal job, would be either as a freelance science communicator specializing in video and online production or it would be with one of the NURC centers or a similar scientific research organization or NGO where I can put my myriad skills to work – oceanography, diver, science outreach, video, animation, web, database, photography (normal and U/W) and ROV pilot (in training right now). But… likely I would not be able to do my own research, which is important to me.

If I were 23 and single, the answer for me would be easy – go for the PhD and study larval and juvenile ecology issues, especially in the mangroves and deep sea. But I’m not 23, or single. And I wouldn’t trade my family for anything, but it does mean I need to figure the 4-6 years of making (if I’m lucky) $30,000/yr while working very long hours into the equation.

One of the major concerns with climate change relates to habitat changes for the plants and animals. Will aspen survive anywhere in the United States? What trees will be able to survive in Connecticut in 2050? 2100? Where will elk be able to survive in 2100?

Of course these aren’t easy predictions to make since each species has distinct environmental requirements. Even more troubling though is that many have complex relationships with other organisms, both beneficial and detrimental. Then there are the often complex food webs that each species is a member. some webs are resilient to loss of several species but others collapse with the loss of only one.

While sea temperatures are generally more stable than air temps in terrestrial systems, many of the marine animals have even tighter requirements for temperature. Even a change in just a few °C can prevent reproduction, reduce lifespans, or even cause death. That is the case with the Icelandic Scallop. In some recent experiments it was found that the scallops had a significantly higher mortality in temperatures above 12°C. Average summer sea surface temperatures off Iceland’s southern coast have been in excess of 10°C in recent years and have been rising. A +2°C change over the previous decades has brought the average summer sea surface temperature very near the scallop’s maximum threshold. While the scallops are still able to survive, there has been a marked increase in adult mortality.

Increasing temperature may not directly be the primary cause of the recent increases in mortality of the scallops, though it has been strongly implicated. In recent years, a protozoan parasite has affected much of the stock of C. islandica around Iceland. As with the scallop itself, many protozoan parasites have been found to have temperature thresholds and ideal temperature ranges. For instance Perkinsus atlanticus populations under controlled experiments did not grow, in temperatures of 5°C, grew slowly at 16°C, and grew quickly at 20°C and 26°C. It also failed to grow and died out after 4 days at an experimental temperature of 37°C. Similarly, two other protozoan parasites of interest on the Atlantic Coast are also temperature controlled: Parkinsus marinus, the cause of the disease dermo in oysters, requires temperatures above 25°C to thrive, Haplosporidium nelsoni, which causes MSX in oysters (although it can survive and multiply at temperatures of 5°C-25°C) requires temperatures above 20°C to infect a new oyster. Temperature is likely also a controlling factor in the spread of the protozoan infecting C. islandica.

While the Iceland Scallop is what instigated this post, the topic of climate change and its effect on marine animals, particularly fish, is one I have been thinking of a lot lately. In much the same way that the scallops are temperature limited, fish have ideal and survivable temperature ranges, and temperature can play a significant role on growth and reproductive success. Complicating the issue is that many of the fish have very specific habitat preferences or needs as well.

Take for instance the Atlantic Wolffish (Anarhichas lupus) a species of increasing concern in the Gulf of Maine, if fact they are likely to be soon added to the Endangered Species Act. They are a wonderful (dare I say beautiful) fish with some great characteristics and a face only a mother, or a crazy marine biologist, could love! They feed mainly on molluscs, crustaceans and echinoderms using their huge canines. They are a large benthic fish, growing up to 5 feet and weighing up to 40 pounds.

They are also a slow growing and late maturing species. Growth and maturity varies with temperature fluctuations, but generally they are reproductively mature by 6 years or about 16 inches total length. Spawning pairs of male and female form in the spring with actual spawning period varying, possibly as a function of temperature. As with many species, reproductive success increases as females grow larger and older, producing both more eggs and more viable eggs (ranges from 5,000 to 12,000 eggs per season). The female lays her eggs in holes and around boulder reefs. The male then begins a fast, loses his teeth, and guards the eggs for four to nine months of egg incubation (again a function of temperature). Four to nine month fasting and guarding the eggs. Think about that one guys!

One of the cool things about wolffish is the presence of anti-freeze in their body, which allows them to survive, even thrive, in extremely cold waters. In the wild they have been caught in trawl surveys in waters from -1.9°C to 14°C. In the laboratory they survived temperatures as high as 17°C, but feeding was strongly negatively correlated with the higher temperatures.

So temperature is a major factor on the wolffish, but so is habitat. Wolffish are most often found in rocky reefs or seaweed beds on hard substrate from 80m to 180m depths, but range as deep as 650m and can, on occasion, be found in coastal shallows. My most memorable dive in New England remains being about 3 feet away from a 4 foot wolffish in the cove just off Avery Point in late November.

Young wolffish keep to the deeper, colder part of their range where temperatures remain -1°C to 4°C. Only mature fish are found in shallower ranges and higher temperatures with an upper temperature limit of 10°C.

My thoughts recently have related mainly to mapping the current and potential future ranges of some of these animals using habitat suitability modeling techniques in geographic information systems (GIS), including especially ecological niche factor analysis (ENFA). Using what we know of their habitat requirements (for the wolffish: -1°C-10°C, boulder reefs for spawning, 80m-200m depth, and abundance of lobster, crab, urchin or molluscs) we can map the current optimal and sub-optimal ranges. It doesn’t mean they’ll be there, but it is where the potential for finding them should be highest, based on our understanding of their requirements. By altering the temperature and depth components to match forecasts based on climate change models, we can look ahead to forecast the likely range of the animals, and even the decade by decade march or retreat of suitable habitat.

An example of using mulitple habitat factors with multipliers to determine ecological niche. From http://www2.unil.ch/biomapper/

For some animals the outlook is pretty bleak. The combination of habitat requirements and temperature requirements will drive them completely out of the Gulf of Maine and potentially out of the Western Atlantic entirely. There are many fish that are at their breeding temperature limits in the Gulf of Maine already, including many commercially important species. Some marine animals are existing in virtual islands of suitable habitat formed by complexities of depth, substrate type and complexity, currents and temperature, among many other factors.

The challenge is to identify, for each species or community, which of these factors are most important for both the organism’s survival and our modeling efforts. Unfortunately, especially in the marine realm, there is still so much we don’t know about the ecological requirements of may of the animals and communities. Even mapping the seafloor at resolutions comparable to our maps of terrestrial areas continues to be challenge. It often surprises many people I talk to when they find out that almost all our knowledge of marine animal populations and habitat characteristics comes from commercial fisheries and from sample trawls by the NMFS. Most species that are not targets of fisheries or considered commercially important have not been studied extensively, if at all.

In the marine environment it is very challenging to accurately predict how communities will respond to warming waters and how individual species ranges will change, simply from lack of direct observation. We are getting better at using the important data we do have, and have identified proxies for the data we simply do not have, but we need more time in the water with ROV’s and DSV’s for direct observations, especially of the continental shelf and deep sea ecosystems.

The Johnson Sea Link II being deployed from the R/V Seward Johnson for Life on the Edge 2005

Some people question the real need for manned submersibles, arguing that ROV‘s like Hercules, Jason and Kraken II can do anything a manned vehicle can do, only better and safer. It’s a valid question, and one that needs to be repeatedly asked, especially as more advanced ROV’s designed from the ground up for science come on line. But my answer today is that there is a need for both of them still. ROVs can not go everywhere an HOV can, and their mobility and responsiveness are limited, compared to HOVs, by the ever-present tether to the mother ship. An ROV also lacks the ability to provide 3D visual-spatial analysis and true in-situ contextual observations which only a scientist and pilot on the spot can provide, at least with todays technology. ROV’s while extremely capable are still a telepresence technology, and many of those that have used both HOVs and ROVs, such as Dr. Craig McClain at Deep Sea News, attest that something significant is lost in that translation.

These experiences combined to give me a first hand knowledge of an environment, that previously I had only studied remotely. I studied the deep sea for three years before my first deep dive and my understanding, although incomplete, of this environment has radically changed since those dives in the JSL.

Perhaps more important, these manned submersibles stir the imaginations of young minds, leading them, like me, to dream abut exploring the sea, maybe one day sitting in awe within a submersible 1 kilometer below the surface, surrounded by organisms we are still only beginning to comprehend fully.

Please help us let those in control of the JSLs fate aware of the JSLs importance to science and to our ability to understand the seas and stir the imaginations of the young explorers in our midst. Young explorers like Johann. Please GO SIGN A PETITION TO STOP THEIR LOSS.

So, a bit more on the new NOAA Cooperative Institute, since that also directly affects my future. NURC-NA&GL, along with all the other NURC centers, are NOAA supported, non-federal organizations under NOAA’s National Undersea Research Program (NURP). NURC-NA&GL’s mission is as a center for excellence in research related to the North Atlantic and Great Lakes region. They work with NOAA scientists on long term research goals including developing oceanographic research technologies (such as the Kraken II), fisheries and conservation research, historical site identification and documentation along with major outreach efforts. They are also tasked with Postdoc and graduate student training to provide the next generation of oceanographers. Unfortunately NURC-NA&GL may lose all NOAA funding with the establishment of the new center at HBOI, as it will replace the four existing East Coast NURC centers, including the one at UCONN. Personally I think cutting support for the existing centers is a mistake, even though the new Cooperative Institute sounds wonderful.

So my summer and the next two years are set, sort of. There are still some questions (second year funding, nailing down the thesis topic, now that we have health insurance, do we have another baby, etc., etc.), but at least the path forward is clear enough to begin charging down it! The summer will be hectic, split between two projects for NURC (video and GIS outreach products for high school teachers and students to use and possibly video highlights from a recent deep sea cruise), two projects for Prof. A. (both habitat related), a cruise for Prof. A, and then the remainder of my time will be dedicated to finishing up an outreach book and cards for grades K-12+ on molluscs. Whew!

*Johann pointed out that even Playmobil recognizes the JSLs and their full sphere compartments as the iconic submersible.

What is your iconic research submersible? Is it Human operated or remote?

Whatever it is, please do Sign the petition to keep the JSLs operating.

Last week I finished up the last exams, presentations and papers for my undergraduate career. I couldn’t relax and celebrate though, as I had two looming projects that were due on Thursday which had been thrown on the back burner during finals. Finally though, those projects are done and I can sit back and relax and reflect on graduating and whatever that means.

On the whole though I find graduation to be really rather anti-climatic. Maybe it is because I figured I would be headed to graduate school right away, maybe because I thought I would see a clear path forward for some reason. Whatever the case there is no real sense of accomplishment, victory or whatever. Not sure what exactly I thought I would feel, but whatever it was, this ain’t it.

Actually I feel a bit of a loss if anything. No more classes, no more twice a week seminars and no more access to so many journals.

As for graduate school, well, things haven’t worked out quite so well as I wanted there, at least not yet. It looks like I will be working as a tech at Avery Point on a couple of projects for the summer. Not full time work, but enough and most of it dealing with deep sea and ecology, and one week at sea, so very enjoyable.

After that things are rather undecided. There is a potential position for the fall working on a GIS project, and I’m sure something would come up for the spring. In the mean time in the fall I will reapply to work with the professors of interest and look at jumping straight into a PhD program. In the mean time I have been accepted at UCONN, though the project didn’t work out and there is no funding. But maybe I can get one class in each semester, since the state will pay the tuition fees (Combat Vet benefits). We’ll see.

The good thing is I have more free time now to dedicate to spending with my family and doing more photography and blogging again. I also plan to try and do some of the experiments I planned for my masters thesis at home with Tammy and Johann, just for the fun of it. We should be able to get the organisms and we can set up the experimental aquaria. We just won’t be able to do it on a larger scale for the replication needed to do the stats.

For me, today was that day.

Ah, the beauty of Avery Point and the Castle blanketed in a layer of calming white snow. Until the klaxon sounds and sirens wail.

Just to hit the high spots:
Very tired this morning after insomniatic night -> Roads not plowed -> three car pile up on the highway -> highway traffic diverted onto my commute route -> 15 minute commute (+15 for unplowed streets) now takes 57 minutes -> miss Chemistry lecture.

Trying to pack for Ft. Lauderdale trip interupted by two 20 minute fire alarms, both false alarms! Finally got the three crates full of the nav and video systems for the cruise, they are on the way. Hopefully they make it to Ft. Lauderdale and don’t end up in Ft. Leavenworth.

One of three hook and ladder trucks which responds to every Marine Science building alarm. I don’t mean that to imply that there are a lot of alarms.

Laptop died at ~8:40am -> three major projects, all due in next 1-3 weeks on dead laptiop, not to mention three almost complete web site redesigns I figured to complete while on the plane. Fortunately it’s only the video board -> after school Tammy and sick Johann accompany (very tired) me to Genius Bar where they verify, yes it’s the NVidea board. They have replacement mainboard in stock, 3-4 days to replace. Whew! Excellent Indian food from the food court(!!) as celebration.

I managed to get the projects off the laptop before we left for Providence by booting it blind as a firewire harddrive to the iMac. Slow process, but at least I’m safe there. 2 hours sleep in the past 48. This day.. you can have it back (though I’ll keep the vindaloo and nan in the food court, thank you!) Now to sleep perchance to dream, or if not just forget this day.

Dr. McClain over at Deep Sea News recently published a very readable open access paper at PLoS ONE about the potential connectedness of seamounts and nearby habitats. I love that the paper was highly accessible, both in the writing and the fact that anyone can download it from PLoS One and read it for free, especially since, in the case of Davidson Seamount and Monterey Canyon, there are significant implications on management policies, if the goal is to protect and preserve the diversity within the canyon.

A Little Closer to Home

Tim Shank and his lab have been doing a lot of work on connectivity, including genetic analysis, among and between the seamounts of the North Atlantic, especially the New England Seamounts and the Corner Rise Seamounts. Though I haven’t seen any papers yet (I believe Walter Cho is working on this for his Ph.D.) what I have been exposed to is that they are finding connectivity between seamounts and seamount areas, but it is a complex situation with very different connectivity from one species to the next, one depth to the next and one region to the next. Connectivity factors likely include reproduction and recruitment strategies, bathymetry, depth, habitat availability, and hydrodynamics (regional and local).

So Why Should We Care?

Ultimately understanding how these deep sea ecosystems are interconnected is critical for conservation and management of marine resources, including potentially many commercially important species (and the deep sea cephalopods who lay egg capsules on the deep corals, thank you very much!). It needs to be studied further to understand the extent of the connectivity. Connectivity studies have a significant number of challenges though, not the least of which is the seemingly simple task of identifying the interaction time and space scales of the relevant processes. In part these define the boundaries of populations. Identifying all the species using traditional morphological taxonomy and molecular techniques, can be a herculean task as well.

Unfortunately, the seamounts are also being impacted by deep sea fishing. Trawling across the mounts can remove entire communities of slow growing deep sea corals and the complex communities they support, potentially causing a significant effect on the deep sea coral community connectivity as well.

My Tiny Personal Connection

This last year I have been working part time with video captured on several deep sea cruises to the New England Seamount Chain and the Corner Rise Seamounts. Much of the work has been producing support video and a DVD for a variety of presentations, which I can’t present here. I can, however, finally show one piece of the package I put together, which was the last piece we did to give to the funding partners.

Your Seamounts on Fishing

The Future?

While I loved deep sea biology and invert communities before, spending many hours scouring HD video of these invert communities helped really hook me on the idea of studying them long term. As I watched the communities of inverts on the screen I had so many questions about their distribution, their physiological adaptations, limitations on growth and distribution, recruitment triggers, etc… etc… etc. I would love to be able to study these communities, the larval distribution, development and recruitment for the communities and individual species, and the ecological and anthropogenic pressures on these communities.

(Yes, I would still also love to study cephalopods and larval development and ecology within the mangroves, still lot’s of wake-me-up-in-the-middle-of-the-night questions there too!)

Notes

All footage in the piece was taken on the 2005 Deep Atlantic Stepping Stones mission, but not necessarily from the same dive or on the same seamount. The final sequence is the result of an otter door impacting and dragging across a part of the Kükenthal Seamount. An otter-door is a large metal rudder that holds the trawl nets wide open.

There is more impact footage from the mission, including trash and meters upon meters of clean parallel lines cut through communities of coral and sponges where the rollers on the bottom of the net rolled through. The otter door impact zone, however, was the starkest example of clearing the communities from the seamount in the video I surveyed, devastating damage.

10% cuts came already and now the painful ones are coming… not that the 10% cuts weren’t already painful. Hopefully I can find my way into grad school despite the cuts…

Applications are in to UConn, Rutgers and URI for masters programs. Feelers went to Duke and WHOI but both of those are very long shots since the deadlines for this year have already past and they are Ph.D. only programs.
