DEEPEND scientist narrates a deep-pelagic NOAA Okeanos dive in the Gulf
Saturday, April 28th, DEEPEND team member, Heather Judkins, narrated the midwater transect portion of the NOAA Okeanos dive which is part of a cruise currently being conducted in the Gulf of Mexico which ends on May 3rd. Tracey Sutton was also part of the shore-based scientific team, identifying the various fish species that were seen. We had amazing sightings from siphonophores to fishes to even cephalopods!
The goal of the Okeanos cruises are to explore new areas of both benthic and midwater regions around the world. This year, the Okeanos team will be in the Gulf of Mexico and the western Atlantic Ocean. The public are invited to view the live feed of the explorations at this site: https://oceanexplorer.noaa.gov/okeanos/
DEEPEND Conference Presentations and Seminars
Nova Southeastern University kicked off the conference program for the year by hosting a two-day Graduate Student Symposium, which featured seven great talks from DEEPEND’s principle investigators and graduate students. Presentations included: genomic analysis of microbial symbionts found in deep-sea in anglerfish lures and in the water column of the Gulf of Mexico (Lopez et al.), the trophic ecology of a bathypelagic fish family (tubeshoulders, Novotny et al.), ingestion of microplastics by deep-pelagic animals (Bos et al.), the relationship between parasites and size, species, and behaviour of deep-pelagic fishes (Woodstock et al.), the distribution of larval tuna (Pruzinsky et al.) with respect to oceanographic features; the dramatic declines in pelagic fishes (Sutton et al.) and crustaceans (Nichols et al.) in the Gulf after Deepwater Horizon, and classifying pelagic habitat features in the Gulf of Mexico (Johnston et al.)
In February DEEPEND researchers from multiple institutions presented research findings at the Gulf of Mexico Oil Spill and Ecosystem Science Conference (GOMOSES) in New Orleans, LA, and at AGU/ASLO/TOS Ocean Sciences Meeting in Portland, OR.
The aim of the GOMOSES meeting is to bring together a diverse range of researchers from all disciplines who are working on understanding the biological, chemical and physical processes that operate in the Gulf of Mexico. DEEPEND was well-represented, with 11 presentations. Heather Bracken-Grissom and Laura Timm presented work on the genetic connectivity of crustaceans in the Gulf of Mexico with surrounding regions. Heather Judkins and Kris Clark presented their work describing the distributions and diversity of pelagic molluscs (squids and heteropods, respectively). Regarding fishes, presentations described dramatic declines in abundances of deep-pelagic fishes after Deepwater Horizon (Sutton et al.), biophysical coupling in a dominant mesopelagic fish family (lanternfishes; Milligan et al.), and pelagic habitat use by important coastal fishes (snappers/groupers; Velez et al.). Physical oceanographic presentations included work on frontal densities (Hu et al.), methods to track the Mississippi River plumes using satellite measurements (Hu & Le), and a newly developed method to classify pelagic habitat features in the GoM (Johnston et al.).
After the GOMOSES meeting, we were straight on a plane to Portland and the Ocean Sciences Meeting, where (despite an unfortunate outbreak of the flu), the DEEPEND team gave another eight presentations. These included talks describing the ecology of deep-living fishes (see above), and an assessment hydrocarbon contaminants (polycyclic aromatic hydrocarbons) in mesopelagic animals after Deepwater Horizon (Romero et al.). DEEPEND members presented posters describing how microbial communities in the Gulf of Mexico are influenced by diel vertical migrations (Easson et al.), how the assemblage of Oplophorid shrimps has changed since the oil spill (Nichols et al.), habitat classification (Johnston et al.), and the great successes of DEEPEND’s educational outreach program (Musgrave et al.).
To round out our program of talks, DEEPEND’s lead scientist, Tracey Sutton, and DEEPEND’s data manger, Matthew Johnston, gave invited lectures at NSU’s Distinguished Lecture Series. Tracey presented some of his recent work describing the global importance and structure of the deep-pelagic biome to faculty and students and Matt lectured on data visualization and interpretation.
Rock the Ocean’s Tortuga Musical Festival
From April 6-8, 2018, DEEPEND members will be attending Rock the Ocean’s Tortuga Musical Festival at Fort Lauderdale Beach Park in Fort Lauderdale, Florida. DEEPEND members will have a booth at the Conservation Village, which will be located in between the two stages. Our booth will have deep-sea trivia and prizes! Come win some glow-in-the-dark tattoos! A DEEPEND t-shirt raffle will be held each day as well. Stop by and talk to several graduate students and professors about our research during this three day event! We are excited to meet you all and talk about the deep sea!

The DEEPEND timeline, illustrating the diversity of life in the Gulf of Mexico
The DEEPEND timeline was conceived by world-class photographer Danté Fenolio as a platform through which the DEEPEND team could convey the biodiversity that they have encountered in the Gulf of Mexico to the general public. So much amazing biodiversity turned up in the trawling nets that we figured there had to be a way to show it all off. The timeline allowed for a progression through the different cruise trawls and it allowed for a photographic display that we don't think has been developed or matched by any other deep sea biological survey. There are images of some exceptionally rare deep water species and of some more common species. The net result is a celebration of the wildlife living in the water column of the incredibly diverse Gulf of Mexico.

DEEPEND display booth at their Sea Life Facility
Texas A&M University has created a DEEPEND display booth at their Sea Life Facility. This booth allows visitors to learn about deep-sea and epipelagic research through posters, interactive educational games, and educational information hand-outs. Hundreds of visitors (including grade school children, senior citizen groups, new students and parents, undergraduate and graduate students) get to view and interact with the DEEPEND booth each year.
Master's Monday Blog Series
DEEPEND Starts the Master’s Monday Blog Series
We are beginning a blog series which will feature DEEPEND Master’s students and their thesis’ projects. Every other Monday we will post a new blog from one of our graduate students describing their research and what they have found thus far. The blogs will have exciting images related to their work from the field or in the lab. Our very first Master’s student to post a blog was Kristine Clark, a Master’s student at the University of South Florida St. Petersburg, who works on heteropods. What is a heteropod? Find out here!
Today we are featuring our second Master’s student blog by Sebastian Velez, a student at Wilkes Honors College of Florida Atlantic University in Jupiter, FL. Sebastian studies juvenile snappers and groupers found way offshore! Read all about his work here.
