M.S. and Ph.D. candidates shine in 39th Graduate Student Symposium

°®¶ą´«Ă˝ College of Marine Science’s (CMS) 39th annual Graduate Student Symposium

39th Annual Graduate Student Symposium 

Written by Kristen Kusek, Former Communications Director for °®¶ą´«Ă˝ CMS

Fifteen CMS graduate students delivered oral or poster presentations summarizing their research projects as part of the °®¶ą´«Ă˝ College of Marine Science’s (CMS) 39th annual Graduate Student Symposium held on Friday, January 27th. A quick skim of the presentation titles, listed below, underscores the strongly interdisciplinary nature of the CMS research portfolio. The student presentations followed a helpful “lessons I’ve learned” kickoff keynote by CMS alum, Kara Radabaugh (Class of 2013), who manages habitat and oyster mapping and monitoring programs at the °®¶ą´«Ă˝ Fish and Wildlife Conservation Commission in St. Petersburg.

“It was an awesome day for the College,” said Tom Frazer, dean of the CMS. “The students did a phenomenal job organizing the event and delivering their presentations with clarity, passion, and professionalism – and it was a blast finally being able to enjoy the event in person.”

In case you missed it: read full abstracts of each presentation here, view the oral presentations below, and enjoy a scattershot of some of the random fun facts learned throughout the day:

  • Due to climate and coastal change, oyster reefs are transitioning to mangrove-dominated ecosystems in Tampa Bay
  • Iron limits primary production in at least 50% of the surface ocean and it’s challenging to study in part because it’s found in such small amounts in the ocean
  • A fish egg study on the West °®¶ą´«Ă˝ Shelf is a good example of marine research that uses both sophisticated technology (e.g., DNA barcoding) and low-tech tools (toothpicks!)
  • According to reams of data collected from moored buoys over 23 years, the West °®¶ą´«Ă˝ Shelf heats up between February through August and cools start from September through January.
  • In a mysterious mass mortality event in the 1980s, nearly 90% of the Caribbean’s long-spined sea urchin population died. A new mortality event that started in St. Thomas in 2022 benefited from the help of citizen scientists who helped collect valuable data still under investigation.
  • Eddies in the Southern Ocean can make your head spin because they contribute to both the uptake and outgassing of carbon dioxide
  • Jobos Bay, the only national research reserve in the Caribbean, is under threat from ocean acidification to sea level rise and pollution, requiring the development of rapid monitoring tools
  • Scientists are trying to understand why nickel, one of the least well studied trace metals, is found in persistent concentrations in the surface ocean
  • “Killing dots” is an actual scientific exercise associated with ocean map-making and research at sea sometimes offers new adventures beyond research: one lucky CMS student got to visit the gravesite of Sir Ernest Shackleton on South Georgia Island (oh, and see fur seals, elephant seals, and King penguins!)
