Climate Change and Sentinel Monitoring−Mission and Goals

In February 2015 the Journal Ecological Indicators published an article on the development of the Climate Change and Sentinel Monitoring Program and strategy. An abstract and link to purchasing the article is available at the Science Direct website.

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.


The Climate Change and Sentinel Monitoring Program was developed to quantify local changes in the environment brought about by climate change.  The goals of our program are:

1) to collect and synthesize data that will indicate how Long Island Sound is changing

2) provide scientists and managers with the information necessary to prioritize climate change impacts and mitigate and determine appropriate adaptation strategies for these impacts to the LIS ecosystem.

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 Bi-State Sentinel Monitoring Work Group is a partnership that includes EPA Long Island Sound Office, National Oceanic and Atmospheric Administration, New York Department of Environmental Conservation, Connecticut Department of Energy and Environmental Protection, New York Sea Grant and Connecticut Sea Grant. There are formal cooperative agreements/contracts pertaining to funding between these agencies. The two state technical advisory groups include over 60 federal, state, NGO, and university partners who have contributed to all stages of the strategic plan development.

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.
