[Publication] The Project Oceanology time-series has been published!

Posted on March 28, 2019November 5, 2019 by Hannes Baumann

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

Public outreach

NOAA announces funding for our research on sand lance

Posted on September 6, 2016October 29, 2018 by Hannes Baumann

NOAA and Sea Grant fund $800,000 in research to understand effects of ocean changes on iconic Northeast marine life

The Ocean & Atmospheric Research program (OAR) of NOAA and Sea Grant just announced the winners of its most recent round of research funding to better understand the consequences of ocean warming and acidification on key marine resources in U.S. Northeast coastal waters. We are happy and proud that our proposed work on the climate sensitivity of Northern sand lance (Ammodytes dubius) was one of the four projects selected for funding. This is particularly good news for Chris Murray, who for his PhD can now expand his experimental rearing expertise to this important species.
This work will be conducted collaboratively with colleagues from NOAA (David Wiley), USGS (Page Valentine), Boston University (Les Kaufman), and Woods Hole Oceanographic Institution (Scott Gallager).

You can read the official announcement as it appeared on 6 September 2016 on NOAA’s News site.

[Student video] Climate Change: A Future for Fish in a Changing Ocean

Posted on April 26, 2016July 7, 2017 by Hannes Baumann

A big shout-out to Megan, Rainer, and Liz who apart from their intrepid work as volunteers in our lab also excelled here in their video project for MARN3000. They interviewed Profs. Kelly Lombardo, Michael Finiguerra, and Hannes Baumann about aspects of Marine Climate Change and then cut their answers with researched video material from the web. Note the sartorial touch throughout the clip (6 min)!
Well done, all!
