21 March 2019. We are happy to announce that Marine Environmental Research just published our most recent paper about long-term ecological change in eastern Long Island Sound based on data collected by Project Oceanology!For his Master’s thesis, Jacob Snyder painstakingly retrieved and digitized more than 40 years of environmental observations from Project Oceanology. This non-profit ocean literacy organization has educated middle and high school students on boat trips to nearby estuarine sites for decades. For the first time, his work allowed a quantitative evaluation of these data and glimpses into the abiotic and biotic changes in nearshore waters of Eastern Long Island Sound.

Highlights

  • Citizen-science observations revealed rapid warming, acidification, and dissolved oxygen loss over the past 40 years in eastern Long Island Sound
  • Otter trawl catches showed significant decreases in overall species diversity and richness
  • Cold-water adapted species (American lobster, winter flounder) decreased, but warm-water adapted species (spider crabs) increased since 1997

[Talk] Chris & Jake present at the Feng Graduate Research Colloquium


On 12 May 2016, the Department of Marine Science hosted it’s 11th Biennial Feng Graduate Research Colloquium, during which graduate students of the department traditionally present findings of their thesis research and/or give a preview of their future plans.

This year, Chris presented the results of last years study on long-term changes in growth distributions in Atlantic silversides exposed to high CO2 conditions, whereas Jake presented a poster outlining his thesis research on long-term environmental and biological data collected by Project Oceanology.

In addition, Jake took his poster ‘on the road’ already and presented it at the 16th Long Island Sound Research Conference (13 May, Bridgeport, CT), while Chris will give his talk again at the 40th Larval Fish Conference in June 2016 (17-23 June, Chesapeake Biological Laboratory, Solomons MD).
