Climate Change and Sentinel Monitoring

Mission

The Climate Change and Sentinel Monitoring Program (formerly the Sentinel Monitoring for Climate Change in Long Island Sound Program) is a multidisciplinary scientific approach to provide early warning of climate change impacts to Long Island Sound ecosystems, species and processes to facilitate appropriate and timely management decisions and adaptation responses.  These warnings will be based on assessments of climate-related changes to a set of indicators/sentinels recommended by our technical advisory work groups.

Goals

The program was developed to quantify local changes in the environment brought about by climate change. These impacts include but are not limited to: loss or changes in ecosystem functions and processes; disruption in fisheries, aquaculture and other economic commodities; and changes in species population dynamics, including both the loss of and introduction of new species.

The goals of our program are:

  • To collect and synthesize data to identify climate-related changes in Long Island Sound.
  • Provide scientists and managers with the information necessary to prioritize climate change impacts in mitigation efforts and determine appropriate adaptation strategies to address these impacts on the Long Island Sound ecosystem.
Sentinel species: Fledgling saltmarsh sparrows must learn to fly before marsh grasses become inundated during the highest tides of the month. Sea level rise is increasing flooding of their nests earlier than high tides and is putting the species at risk for extinction. The birds’ survival are an early warning sign of the impacts of climate change and sea-level rise. Credit of image at Hammonasset Beach State Park (from video): Jack Silky.

A data citation clearinghouse of research projects for the northeast region, including Long Island Sound is available on the NERACOOS website. A link to the clearinghouse as well as a tutorial on using/adding to the clearinghouse can also be found on UConn’s Long Island Sound Resource Center website.

The Mean Higher High Water (MHHW) is the average of the higher of the two daily high tides. Learn more about maps that project the impacts of sea-level rise on the Sound’s coastline on the SLAMM web page.

Partners

The Bi-State Climate Change and Sentinel Monitoring Work Group is a partnership that includes the EPA Long Island Sound Office, New York State Department of Environmental Conservation, Connecticut Department of Energy and Environmental Protection, New York Sea Grant, Connecticut Sea Grant, and NEIWPCC.

Funding Sources

Funding for the development of the strategic plan was provided by the Long Island Sound Study.  The Long Island Sound Study was also awarded a Direct Technical Assistance grant from the EPA Climate Ready Estuaries program.
