Marine Biologist to Explore Gulf's Uncharted Deep Sea


Jun 26, 2019 (24 days ago) |
ST. PETERSBURG, Fla: The deep sea and the marine life it contains is still largely mysterious. USFSP Marine Biology Professor Heather Judkins and a team of researchers will spend the next two and a half weeks aboard a NOAA Ocean Exploration research cruise to reveal a bit of that mystery and explore never-before-reached areas of the Gulf of Mexico.
We have only investigated five percent of the world's oceans. There is 95 percent that still needs exploring, said Judkins.

The 15-member science team will be out to sea June 7-23 conducting bioluminescence experiments and collecting rare and potentially new species from the deep ocean.

Bioluminescence is the light produced by living organisms using various mechanisms of chemical reactions. The team will examine if bioluminescence acts differently in organisms at depths of 2,000 meters when compared to their shallow-water relatives. The team will be investigating this phenomenon using crustaceans, fishes and cephalopods.

A variety of tools will be used to do so, including a remote operated vehicle that will travel to the sea floor to take images and record video, an illumination system with LED lights - dubbed Eye in the Sea - that will display different bioluminescent patterns to attract creatures towards it and a trawl net system that will collect live animals and bring them to the ship for onboard studies.

The research team, which was awarded a $565,000 NOAA Ocean Exploration Grant, will include scientists from Duke University, Nova Southeastern University and the Ocean Research and Conservation Association.

For Judkins, a cephalopod expert who will focus on identifying and understanding the bioluminescence properties of various octopus and squid, the research expedition will be her ninth time out to sea.

Some of her previous expeditions were part of the DEEPEND consortium funded by the Gulf of Mexico Research Initiative to study short- and long-term impacts of the 2010 Deepwater Horizon Oil Spill on marine life and ecosystems below 200 meters. This multi-year project collected data on contaminants from the spill and impacts on food webs to determine changes in the ecosystem and to marine life from the environmental disaster.
