Seventeen graduate students from the USF College of Marine Science shared their research through oral or poster presentations for the 40th annual Graduate Student Symposium (GSS) on Friday, February 2nd. The breadth of topics covered during GSS illustrates the impressive scope of science conducted at CMS.

“For forty years, the Graduate Student Symposium has given CMS students the opportunity to hone their science presentation and communication skills, and to engage colleagues in a professional setting,” said Tom Frazer, professor and dean of CMS. “I’m very proud of our students, who not only organized this year’s event but presented their research with clarity and composure, demonstrating the passion and scientific rigor that make CMS such an outstanding institution.

GSS kicked off with a presentation from Kara Doran, a CMS alum and oceanographer with the USGS St. Petersburg Coastal and Marine Science Center. Doran’s research focuses on identifying, quantifying, and modeling vulnerabilities of the US shores to coastal change hazards.

The thirteen student presentations that followed included research into biological, chemical, geological, and physical oceanography, from fish spawning to satellite monitoring.

We noted a few fascinating facts shared during the presentations

  • Fish eggs are a good proxy for studying fish spawning patterns.
  • A counterintuitive cooling in the bottom temperature of some regions of the West Florida Shelf may be caused by the loop current.
  • A bright orange anal cone distinguishes Diadema setosum from Diadema antillarum, two sea urchin species experiencing die-offs.
  • A deadly ciliate that kills sea urchins has now been found in the waters of Oman, possibly spread through international boats, diving equipment, or the aquarium trade.
  • Ocean floats can be used to update satellite-derived sea level data.
  • Fish eyes contain isotopes that researches use to understand fish feeding habits.
  • Newborn squid are so small they’re adapted for life in plankton communities.
  • Deep learning models can help scientists detect red tide blooms from space.
  • Mangroves occupy 16 percent of Florida’s coastline, but they’re at risk due to stressors such as sea level rise.
  • Stingrays love Publix shrimp (but please don’t feed wildlife)!
  • Decomposing Sargassum smells like rotten eggs and comes at a huge cost to coastal marine habitats and tourism industries.
