New York, NY, July 2, 2019 - Covering nearly 1,300 square miles, from the East River in Manhattan to New England, Long Island Sound is one of the most important estuaries in the nation with coastal communities of more than four million people. Helping protect and improve the management of this precious body of water with an asset value exceeding $700 billion is the new assignment for oceanic and atmospheric scientist Maria Tzortziou of The City College of New York’s Division of Science.

Over the next two years, Tzortziou will lead this multidisciplinary ecological project funded by the Sea Grant programs of New York (NYSG), Connecticut (CTSG), and the U.S. Environmental Protection Agency (EPA) through the Long Island Sound Study (LISS) . 

Tzortziou and her collaborators, Dianne Greenfield (CUNY Advanced Science Research Center) and Joaquim Goes (Columbia University/Lamont Doherty Earth Observatory), along with their group of students and postdoctoral researchers, will address the challenge of gathering and interpreting data from satellite images of Long Island Sound.  Two early career CCNY postdoctoral research scientists, Brice Grunert and Guoqing Wang, and more than 10 undergraduate and graduate CUNY students will be involved in the project. The team will collect new optical, biogeochemical and ecological measurements in the Sound and will develop satellite algorithms and products for improved monitoring, assessment, and management of estuarine water quality, ecological processes, and ecosystem stressors. This includes development of algal blooms, eutrophication, and hypoxia.

Tzortziou said like many highly populated estuaries in the world, Long Island Sound (LIS) suffers from water quality problems, including high loadings of nutrients, hypoxia, and recurrent harmful algal blooms.

“Satellite observations give environmental monitors and water resource managers the ability to observe changes in water conditions across large areas not feasible with field-based monitoring alone. However, determining water composition and identifying which bloom-forming phytoplankton species are in LIS is from space has been a challenge,” she added. “This study proposes to develop new remote sensing products to improve our knowledge of LIS ecosystem parameters that are critical for management.”

Deb Szaro, acting EPA New England Regional Administrator, said the grant to the Tzortziou team and other researchers would advance ecological research that is critical to protecting and restoring Long Island Sound, one of the country’s most important estuaries.

New York Sea Grant (NYSG), a cooperative program of Cornell University and the State University of New York (SUNY), is one of 33 university-based programs under the National Oceanic and Atmospheric Administration’s National Sea Grant College Program.

Since 1971, NYSG has represented a statewide network of integrated research, education and extension services promoting coastal community economic vitality, environmental sustainability and citizen awareness and understanding about the State’s marine and Great Lakes resources.

Through NYSG’s efforts, the combined talents of university scientists and extension specialists help develop and transfer science-based information to many coastal user groups—businesses and industries, federal, state and local government decision-makers and agency managers, educators, the media and the interested public.

The program maintains Great Lakes offices at Cornell University, SUNY Buffalo, SUNY Oswego and the Wayne County Cooperative Extension office in Newark. In the State's marine waters, NYSG has offices at Stony Brook University in Long Island, Brooklyn College and Cornell Cooperative Extension in NYC and Kingston in the Hudson Valley.

For updates on Sea Grant activities: has RSS, Facebook, Twitter, and YouTube links. NYSG offers a free e-list sign up via for its flagship publication, NY Coastlines/Currents, which is published quarterly. Our program also produces an occasional e-newsletter,"NOAA Sea Grant's Social Media Review," via its blog,
