DEEPEND and C-Image collaborate to examine trophic links in the northern Gulf of Mexico
DEEPEND and C-Image researchers (T. Sutton, S. Murawski, H. Judkins, I. Romero and others) met in December to process pelagic fishes that were collected during a C-Image longline cruise that occurred in August in order to examine the possible linkages between these fast, deep-diving fishes to the midwater organisms that are the focus of DEEPEND research. Over 45 fish stomachs (including Lancetfish, Swordfish, Silky Shark, and others) were examined and contents were identified to the species level when possible. The stomach contents were in surprisingly good condition with many species successfully identified. There were multiple midwater fishes and cephalopods that were discovered which shows a strong link between the two groups by way of predator/prey interactions.
DEEPEND Co-PI coordinated the triennial Cephalopod Conference in November
Heather Judkins was thrilled to coordinate the triennial CIAC Conference in St. Petersburg, FL in November. CIAC (Cephalopod International Advisory Council Conference) was formed in 1983 to promote the sharing of cephalopod research around the world. This CIAC conference drew 230 scientists to the region for two-day practical application workshops as well as the five-day conference with over 100 oral presentations, 18 Lightning talks, and 150 Poster presentations. There were 30 countries represented at the event and attendees enjoyed a welcome reception at The Florida Aquarium, field trips around the region, and a final CIAC Celebration banquet in Gulfport, FL. During the week, Dr. Judkins was also elected the next CIAC president until 2021 at the next conference which will be held in Portugal. Overall, it was a great success!

Oceanic Ecology Lab Featured on the History Channel
On August 3rd, 2018 Dr. Tracey Sutton's Oceanic Ecology lab at Nova Southeastern University was featured on the new series "In Search Of" on the History Channel with host Zachary Quinto. Check out this episode about the deep sea!! You will learn about a new snaggletooth species (Astronesthes) discovered through DEEPEND's research!
Grad Student Richards Uses Fish Muscle Tissue to Explore Deep-Sea Food Web Structure
The deep-pelagic habitat (200 m depth to just above the seabed) is the largest habitat in the Gulf of Mexico, yet we know very little about it compared to coastal and shallow-water habitats. Our limited understanding of this major marine habitat makes it extremely difficult to assess the effects of disturbances such as the Deepwater Horizon oil spill. Travis Richards seeks to better understand the structure of deep-pelagic food webs by tracing the energy flow from the food web base through higher trophic levels. His research will help expand our understanding of the deep-pelagic habitat and serve as a reference point for future studies and response efforts.
The GoMRI community embraces bright and dedicated students like Travis Richards and their important contributions. The GoMRI Scholars Program recognizes graduate students whose work focuses on GoMRI-funded projects and builds community for the next generation of ocean science professionals.
Travis's work is a feature story on the GoMRI website. Read about it here
Life Aboard a Research Ship
One of the DEEPEND team members, Dante Fenolio, our resident photographer, conducted a series of short videos during our recent cruise highlighting "Life Aboard a Research Ship" through his Facebook page. If you're interested about the many pieces it takes to make a research cruise successful, check out the 20 or so video clips! Many of the Point Sur crew and the DEEPEND science team discuss their roles while onboard. Enjoy!
First DEEPEND Synthesis Workshop
The DEEPEND Consortium held it's first Synthesis Workshop at NSU's Guy Harvey Oceanographic Center in Dania Beach Florida on May 14th-15th, 2018. The workshop was well-attended by 50 consortia members, students, and affiliated scientists, including the following external participants:
Stacy Calhoun (ULL; Deep-pelagic zooplankton)
Kait Frasier (SIO; Marine mammal collaboration)
Dean Grubbs (FSU; Deep-demersal predator collaboration)
Dan Hahn (NOAA Office of Response and Restoration)
Bill Hogarth (GoMRI Research Board Member)
John Quinlan (NOAA NMFS SEFSC – NRDA water column assessment)
Steve Murawski (USF; C-IMAGE I-III PI; epipelagic top predator collaboration)
Kelly Robinson (ULL; RFP VI co-PI – Deep-pelagic zooplankton)
Jim Ruzicka (OSU, RFP VI co-PI – ecosystem modeling)
Verena Wang (USM: – Deep-pelagic zooplankton, larval fish time-series)
Eric Weissberger (NOAA NMFS Monitoring and Adaptive Management)
Chuck Wilson (GoMRI Chief Science Officer)
We thank all participants who joined us in this synthesis effort. The meeting was recorded and will be transcribed for a report.
