Rosenheim leads RPO Workshop at WHOI

ST. WOODS HOLE, MA - Brad Rosenheim teamed up with Dr. Ann McNichol, Dr. Valier Galy and others from Woods Hole Oceanographic Institution to offer the first Ramped PyrOx (RPO) workshop, sponsored by the National Science Foundation. The event lasted one and a half days, and was attended by USF College of Marine Science (CMS) graduate student Cristina Subt and USF CMS professor Eugene Domack. All three USF attendees chaired panel discussions about the technique, a tool central to several investigations by the Southern Oceans group at USF CMS. The workshop will produce an article to Eos, the news outlet of the American Geophysical Union, and a white paper to NSF.

USFCMS grad students receive two NSFGRFP Fellowships and one Honorable Mention

ST. PETERSBURG, FL - Three USF College of Marine Science graduate students have been recognized by the National Science Foundation's 2016 Graduate Research Fellowship Program. Kara Vadman, a geological oceanography graduate student in Amelia Shevenell's lab, and Jonathan Sharp, a chemical oceanography student in Dr. Bob Byrne's lab, received the prestigious 3-year NSF fellowships and Amanda Sosnowski, a biological oceanographer in Heather Judkins' and Mya Breitbart's labs earned an honorable mention.  The highly competitive NSF Graduate Research Fellowship Program recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering, and mathematics disciplines who are pursuing research-based graduate degrees.   


"What is your research topic on, Kara Vadman?"

"My research seeks to advance our understanding of Earth’s climate system by unraveling dynamic ice-ocean interactions that take place on the East Antarctic margin. I am conducting a paleoceanographic study of bottom water temperatures proximal to the marine terminating Totten Glacier-Moscow University Ice Shelf System using foraminifera geochemistry from a suite of marine sediment cores. The microfossils provide a record of oceanographic change over the past several thousand years. This project will enable us to determine the role that warm water masses have on ice sheet stability, which is immediately relevant to concerns that ongoing warming is destabilizing Antarctica’s ice sheets, resulting in global sea level rise."


"What is your research topic on, Jonathan Sharp?"

"I am a student in Robert Byrne's lab studying the marine carbonate system. I am investigating the influence of particulate organic matter on the titration alkalinity of seawater. I am also working on developing novel in situ sensors to measure carbonate system parameters. I'll be sailing on the 2016 West Coast Ocean Acidification Cruise in May to gather important water chemistry data and to broaden my scientific perspectives."


"What is your research topic on, Amanda Sosnowski?"

My Master’s research is focused on intraspecies variation and population connectivity in deep-sea cephalopods, as well as linking taxonomic diagnoses with DNA barcodes. My main research objectives include: determining genetic diversity in deep-sea cephalopods at the species level, determining genetic connectivity in deep-sea cephalopods at the regional level across different stations in the Gulf of Mexico (GoM), and determining genetic connectivity in deep-sea cephalopods at the population level across disjunct basins separated by the Florida Peninsula (GoM and Northwest Atlantic Ocean). By studying the genetic diversity and population connectivity in deep-sea cephalopods, my research will lend a fuller picture to the amount of gene flow amongst cephalopod species in the GoM and Northwest Atlantic Ocean. It is imperative to understand the gene pool and genetic exchange of deep-sea cephalopods to determine if demographic independence exists among populations, and subsequently, assess their vulnerability to impact and recovery after disturbance. 

Congratulations to Kara, Jonathan, and Amanda!

Dinorah Chacin awarded the National Science Foundation, GROW Fellowship

ST. PETERSBURG, FL - Dinorah Chacin was awarded the National Science Foundation, Graduate Research Opportunities Worldwide (GROW) fellowship to engage in international research collaboration with Stockholm University in Sweden. This six-month experience will allow Dinorah to work with Dr. Charlotte Berkström and conduct field studies in Mafia Island, Tanzania. Dinorah will be investigating the ecological roles of native algal beds in East Africa as well as those of introduced (through open-water farming) non-native algae. The study aims to 1) identify fish communities that utilize native and introduced algae as habitats, 2) identify herbivores that consume either algae, and 3) examine the connectivity of introduced and native algae to other shallow-water habitats. While conducting field research, local communities, especially fishermen and algae farmers, will be encouraged to participate and learn the importance of assessing the ecological influence of farmed algae through first-hand experience. The results of this study, along with the local’s ecological knowledge, will be used to design and implement an optimal management plan for algae farming in the area, focused on achieving a sustainable practice.

This experience will complement Dinorah’s ongoing doctoral research at the College of Marine Science, University of South Florida, which aims to understand how seascape heterogeneity influences ecological patterns and processes in coastal systems. Until now Dinorah’s dissertation has concentrated on work she has completed in the tropical/subtropical western Atlantic region. The GROW experience will therefore allow Dinorah to expand her research into international and highly understudied coastal systems such as those in African seascapes.
