Jennifer A Flannery

My research focuses on using massive coral species (Orbicella faveolata and Siderastraea siderea) to reconstruct paleo-climates and paleo-environments. Specifically, I analyze trace metal concentrations of three elements (Sr, Ca, and Mg) present in the calcium carbonate skeleton of these massive coral species.

Research Experience

Chemist, Department of Interior, United States Geological Survey, St. Petersburg, FL, 2008-present

  • Utilized corals from the Dry Tortugas to examine climate variability in the Gulf of Mexico over the past 200 years
  • Used x-ray image analysis to determine chronology and coral growth rates for three different massive coral species
  • Worked with Orbicella faveolata and prepared samples for sea surface temperature reconstruction using elemental ratios (Strontium/Calcium) and isotopic (d18O) analyses
  • Trained junior scientists and interns on laboratory techniques

Graduate Research Associate, University of South Florida, St. Petersburg, FL, 2005-2008

  • Applied inorganic and organic compositional, isotopic, and molecular analyses to understand ocean-continent interactions in response to abrupt climate change
  • Operated laboratory equipment including a CM5104 UIC Carbon Coulometer (combustion and acidification), Beckman LS Series Coulter, Hewlett-Packard 5890 Series II Plus Gas Chromatograph with a Flame Ionization Detector, Varian 320-MS TQ Mass Spectrometer coupled to a Varian CP-3800 Gas Chromatograph, Thermo-Finnigan Delta Plus XL Continuous Flow Mass Spectrometer interfaced with a Hewlett-Packard 5890 Series II Plus GC and Carlo Erba Elemental Auto Analyzer, and Dionex ASE® 200 Accelerated Solvent Extractor
  •  Developed and established new procedures of organic lipid extraction from marine sediments
  • Participated in a week long research cruise on the R/V Cape Hatteras in the Gulf of Mexico in October, 2005 to collect sediment cores and water samples as part of the USGS Gulf of Mexico Hypoxia Zone Project
  • Participated in a week long research cruise on the R/V Pelican in the Gulf of Mexico in April, 2007 to collect sediment cores and water samples as part of the USGS Gulf of Mexico Hypoxia Zone Project and the USF Late Holocene Climate Change Project
  • Acquired field experience with oceanographic research equipment (including CTD and niskin bottle deployment, box-coring, piston coring, and in-situ water filtration)
  • Attended and presented research at national and international conferences and composed scientific manuscripts for publication in peer-reviewed journals
  • Trained and supervised an Eckerd College undergraduate summer intern

Undergraduate Research Intern, University of South Florida, St. Petersburg, FL, 2004

  • Assisted current graduate students with laboratory work and research, including conducting experiments and operating laboratory instrumentation
  • Prepared a variety of samples for various analyses, and synthesized data and information into oral presentations
  • Researched certain topics of interest in peer-reviewed literature, textbooks, and on the internet
  • Transported samples to other laboratories to undergo further analyses
  • Ordered instrument parts and chemicals as needed to perform various procedures
