Where: Fort Lauderdale Beach, in the Conservation Village
What: The DEEPEND Booth will have deep-sea trivia, guessing games, and a photo booth this year! You can win glow in the dark anglerfish tattoos or a DEEPEND t-shirt! Come visit our booth while enjoying the sights and sounds of the festival!
As a nominee for ACM Festival of the Year, saving the oceans and shifting to more sustainable habits is something we all want to do, but where do we start? This question can be daunting when wanting to make lifestyle changes to help our oceans. It’s nice to have a little education on how you can make a difference! This is what Conservation Village at Rock The Ocean’s Tortuga Music Festival is all about – educating fans on conservation initiatives, lifestyle changes, and raising awareness for the protection of our oceans. We will be joining 30+ other leaders in ocean conservation to deliver simple, unique ways fans can help save our oceans.
Tortuga Music Festival has grown over the past seven years to become one of the largest music festivals in the world. With this growth, the conservation efforts have grown as well. A few of the on-site efforts this year will include:
- Minimizing Waste and Reducing Single Use Plastics:
- Festival Wide recycling
- Food vendors using only compostable serviceware
- Provide free water refill stations. Fans will be encouraged to bring and use their own refillable water bottles.
- No plastic water bottles. Fans can refill their water bottles at a water refill station or Open Water in aluminum cans will be available for purchase.
- No plastic straws. We have a straw by request only policy, substituting plastic straws with ocean friendly paper straws.
- Donation of all leftover food.
- New in 2019: Reduce single-use plastic by purchasing a limited Tortuga Music Festival Pint Cup! Purchase one with your first drink and use it all weekend long!
- Supporting Sustainable Food Systems:
- Tortuga is committed to only serving sustainable seafood. This means that any seafood item served at the festival must be caught or farmed in environmentally responsible ways. Vendors must source seafood that is listed as a “Best Choice” or “Good Alternative” by The Monterey Bay Aquarium Seafood Watch program.
- Additionally, we are committed to only serving meats raised without the use of antibiotics and produce that has been sourced from within 200 miles of the festival site. This is in order to support the local community and promote positive animal welfare practices.
- Encouraging Alternative Transportation:
- Fans will be encouraged to take advantage of alternative transportation options that reduce the emissions associated with fan travel to and from the festival. Alternatives include:
▪ Water Taxis

The Deep-Sea Biology Symposium is an international scientific gathering and I was privileged and honored to have been able to attend the 15th such symposium in Monterey, California, thanks to two travel awards. The first was sponsored by FAU’s Environmental Sciences Program for winning Best Student Poster at the annual retreat in 2018. The second was an award from the DEEPEND Consortium through funds donated to them by Rock the Ocean Foundation for participating in the Tortuga Music Festival’s Conservation Village. Of course, the session topics at this deep-sea conference were utterly fascinating. Even though I have been a graduate student with DEEPEND for three years now it really felt like I was being told about the deep ocean for the first time. It was simply a thrill to spend a week learning about the biology of hydrothermal vents, hadal zone fishes, bioluminescence, cold-water coral reefs, bizarre and intriguing invertebrates like giant larvaceans and tomopterid worms, and that the blackest color black imaginable is on the skin of a fish! Mind blown. But the science and the scientists really impressed me the most. The quality and caliber of science coming from these researchers, who hail from all over the world, is breath-taking. What's more: almost all of these folks knew each other as old friends! A global community of deep-sea researchers, pushing the boundaries of knowledge on what is truly one of the last frontiers of human exploration, are actually all old drinking buddies! As for myself, I quickly found a large and warm group of fellow grad students and post-doc researchers, themselves from all parts of the globe, with which to explore Monterey. Monterey is a gorgeous place and I truly believe the Bay, the Aquarium and the Research Institute there are national treasures. I made many new friends and traded business cards and kind words with fellow students and veteran researchers alike, sharing our love of ocean life with geek-like enthusiasm. However, we also learned a great deal just how much is at stake for our beloved oceans. Whether it be oil spills, deep-sea mining, plastic pollution, over-fishing, or global warming, there are innumerable perils humankind has wrought on the oceans. Between this call to arms, the beauty and awe of the science, and the comradery of the community, I have never been so inspired to remain in academia and contribute to a scientific field than I was by this symposium. With no small amount of effort, and a whole lot of luck, I hope to attend the next symposium in Japan to see my new friends again and to share in their discoveries while working to keep our oceans healthy and diverse well into the future.
We are in the home stretch for this DEEPEND cruise with only one trawl left to process on our last day out here at sea. This cruise has been just as productive as every other trip we have conducted with lots of hard work, long hours, and rewarding finds! Here are some fun facts from our six cruises out here in the Gulf of Mexico:
We have found great diversity of species for the major taxa: 61 cephalopod species, 120 crustacean species and 627 fish species! These are important numbers as in the past the midwater habitat was not considered a particularly diverse region.
Here are the winners for the most abundant animal in each category:
Most abundant fish: Cyclothone sp.
Most abundant crustacean: Euphausiids
Most abundant cephalopod: Pterygioteuthis sp. (P. gemmata and P.giardi)
With regards to operations, here’s what we know:
Number of miles traveled: ~6496 miles on the R/V Point Sur out here in the big blue!
Total number of MOC trawls successfully deployed and retrieved: 122
Total number of hours the MOC was in the water: 671 hours
We have 1764 hours of acoustics data collected.
We have ~40,000 species and team photos from Dante Fenolio’s efforts.

What have we found so far? We have found five cephalopod species and more than 20 species of fish that are new to science (descriptions are in the works) and we have approximately 180 fish species that are new records for the Gulf. We have found that each time out here, we have been surprised about how changeable the water conditions have been as we go down the water column- from moving across eddy features to observing and documenting the outward flow of the Mississippi River. We have found that hard work is exhausting but absolutely rewarding as we have so much science to share with all that we have found so far! We have been able to support more than 30 students, research technicians, and post docs through the DEEPEND program to date. This has been essential to maintaining our productivity for the last four years.
So, how has all of this amazing science been possible? We give a HUGE thank you to NOAA/NRDA and GoMRI for this opportunity to explore this unknown region of the Gulf. We now have eight years of continuous data in the same region, using the same methods which allows us to explore connections, gaps, and patterns that occur within and between these depth layers.
We also thank Captain Nic and the crew of the R/V Point Sur for their tireless work to keep our science moving each and every cruise. We wouldn’t have any science to share without you guys along the way! Thank you!
Each DEEPEND team member wants to thank their home institutions for their support for this effort over the last four years. These cruises have an extremely surprising and enlightening endeavor and we have lots more science to report on from these efforts. We expect to have research output and publications continuing for at least the next ten years. Where would we be without Matt Johnston, our data manger and land connection while on our cruises? Thanks to him for all his efforts! April Cook, our rockstar project manager has kept us all in line for the last four years and continues to do so, thank you! And, we can’t go without thanking our amazing director, Tracey Sutton- his work ethic combined with humor has allowed us all to grow as a team over the years, thanks, Tracey!!

Keep checking in on us for more news, publications, and highlights from the DEEPEND science team as we continue to “fish for answers”…. Until we sail again!
My name is Nina Pruzinsky. I am a graduate research assistant in Dr. Tracey Sutton’s Oceanic Ecology Lab at Nova Southeastern University. I defended my master’s thesis on the “Identification and spatiotemporal dynamics of tuna (Family: Scombridae; Tribe: Thunnini) early life stages in the oceanic Gulf of Mexico” in May and will continue working in Dr. Sutton’s lab post-graduation. In my thesis, I determined characteristics that differentiate juvenile tuna species, which have been previously poorly described, and then mapped the distributions of the most abundant species (little tunny, blackfin tuna, frigate tuna, and skipjack tuna) collected in the Gulf of Mexico from 2010-2011 and 2015-2017.

With that being said, this is my first DEEPEND cruise! I am ecstatic to be a part of the team that is out surveying the Gulf’s deep pelagic ecosystem. I have worked with these specimens in the lab for the past two and a half years, and it is incredible to see the specimens when they first come up in the nets! The different coloration patterns and photophores of these deep-sea fish are amazing to see! On this DEEPEND cruise, I am working as the database manager and work alongside Natalie Slayden. Our job is to back process the fish specimens identified by taxonomists Drs. Tracey Sutton and Jon Moore. Check out Natalie’s blog below to learn more about our jobs at sea.
In regards to my research, I am continuing to sample the larval and juvenile tuna in the Gulf of Mexico. Scombrid counts on this cruise exceed all other DEEPEND cruises thus far! On this cruise, we have collected various scombrid species and life stages. The majority of our catch has consisted of larval and juvenile little tunny. Due to the collaboration with C-Image III, we have also fished/caught adult tunas as well. As Heather mentioned, we are collected tissue samples of these adults for C-Image III and for stable isotope analyses conducted by Travis Richards.

We have collected larval and juvenile frigate and bullet tuna. At the juvenile stage, these two species cannot be differentiated; thus, we are running genetic analyses to determine which species this specimen is (see picture below). Additionally, we found a skipjack tuna in the stomach of one of the adult little tunny that Max Weber caught on the cruise! The MOCNESS also collected a larval skipjack as well. We also caught an adult bonito, and Gray Lawson, our MOCNESS operator, caught an adult yellowfin tuna. It is exciting to see the diversity of tuna species collected this trip!

As I spent the majority of my thesis surveying larval and juvenile tunas, this cruise was the first time I saw adult tunas. We had several schools circling the boat, which was very exciting!! Hoping for more tuna sightings and catches as the cruise continues! J
The DEEPEND program has provided the opportunities for collaboration in so many areas over the last four years! In the education and outreach arena, we have been working with the Oregon Coast Aquarium (http://aquarium.org/education/oceanscape-network/) who highlights DEEPEND work and created our DEEPEND Vertical Distribution poster. This collaboration was made possible by one of our EO team members, Ruth Musgrave, who oversees our K-6 education components. We have worked with middle and high school teachers from Florida to Texas through our Teacher-At-Sea program and have remained in contact with many of them years after their at-sea experiences. We have also collaborated through community efforts such as the St. Petersburg Science Festival where both DEEEPEND and C-Image consortia shared space to enlighten children and adults about our offshore projects through interactive games and question and answer sessions.

Throughout the four years, our research efforts have also expanded outside of our consortium and other GoMRI groups. For example, in my case, I have been collaborating with other cephalopod researchers around the world about things we are discovering here in the GoM. From new species descriptions to future publications, I have truly benefitted from the DEEPEND work we have conducted to date!
One exciting new collaboration is the alignment of DEEPEND and C-Image III (http://www.marine.usf.edu/c-image/) consortia to tackle an existing gap in the offshore datasets we’ve been collecting. If you look to the DEEPEND shiptracker on our website, you will see the stations we are visiting for our MOC10 sampling work. What is great is that on August 10th, the C-IMAGE III team will head out to the same stations we’ve visited to conduct their longlining project. A total of 36 pelagic longline sets will be made with two gear sets per station (one during daylight and a second at night). This add-on longline survey will evaluate the abundance, food habits, and population demography of the predators, to take tissue samples for toxicology studies, and to evaluate the stomach fullness, species composition and to obtain genetic samples of prey items.

Basically, C-IMAGE III will be collecting stomachs for a subsest of our consortia teams to examine to attempt to fill the gap of knowledge between our deep-sea organisms and their large pelagic fishes. What is the gap? Food web connections are difficult as there are many, many variables involved with who eats whom, when does everybody eat, at what depth are they eating, etc. If we can connect the DEEPEND organisms with these more shallow top predators, we will gain a better sense of the energy transfer that occurs between these two groups. We will be working with this new project when everyone is back on land and in the labs!
