Climate Change Vulnerability Assessment for Long Island Sound via Sentinel Monitoring

Created: 3/30/2010 - Updated: 3/02/2020


The Long Island Sound Study (LISS) received a technical assistance award from the U.S. Environmental Protection Agency’s Climate Ready Estuaries Program to create a bi-state sentinel monitoring strategy with the Connecticut Department of Environmental Protection (DEP). The project team is identifying climate drivers, predicted indicators, and responses to create an adaptive monitoring strategy for Long Island Sound.


LISS is working with the Connecticut DEP to create a sentinel monitoring strategy that will help scientists and managers understand and respond to climate change in the region. Project leads are working to summarize some of the existing monitoring efforts in Long Island Sound in order to identify information gaps in terms of understanding climate-driven change. This project will help monitoring efforts to be more efficient by focusing on particular impacts and issues in specific areas of the Sound. The project aims to answer three questions:

  1. What monitoring efforts exist?
  2. What new monitoring is needed?
  3. What indicators/sentinels (and their prioritization) will create an overall effective strategy for Long Island Sound?


LISS received a technical assistance award from the Climate Ready Estuaries Program in 2009 to develop a bi-state sentinel monitoring strategy to monitor and predict climate change impacts in Long Island Sound. The project team, using current research and lessons learned from assessments of climate change monitoring in other estuarine and coastal areas, is identifying climate drivers, indicators, and responses to create an adaptive monitoring strategy.

Outcomes and Conclusions

The primary project output is a strategic monitoring plan, which will be the basis for a climate change monitoring program for the entire Long Island Sound.

Project Contact(s)

The Long Island Sound Study (LISS) works with federal, state, and local partners to restore and protect Long Island Sound. In 1994, the program’s goals were identified in LISS’s Comprehensive Conservation and Management Plan (the CCMP).

The DEEP achieves its mission through regulation, monitoring, inspection and enforcement, and licensing procedures that help control air, land and water pollution in order to protect health, safety, welfare and natural resources.

The Climate Ready Estuaries program works with the National Estuary Programs and other coastal managers to: 1) assess climate change vulnerabilities, 2) develop and implement adaptation strategies, 3) engage and educate stakeholders, and 4) share the lessons learned with other coastal managers.
