Connecticut

Connecticut, the southernmost state in the New England region of the United States is named after the Connecticut River, a major river that bisects the state. The Connecticut River cuts through the center of the state, flowing into Long Island Sound. Connecticut consists of temperate broadleaf and mixed forests. Northeastern coastal forests of oaks, hickories and maple cover much of the state.

The Response of Coastal Wetlands to Sea-level Rise: Understanding how Macroscale Drivers Influence Local Processes and Feedbacks

The purpose of this work is to advance our understanding of how coastal wetland responses to sea-level rise (SLR) within the conterminous United States are likely to vary as a function of local, regional, and macroscale drivers, including climate. Based on our interactions with managers and decision makers, as well as our knowledge of the current state of the science, we propose to: (a)...

Water Quality Sampling and Monitoring of the Pawcatuck River Watershed

The Pawcatuck River and the Pawcatuck River Estuary and Little Narragansett Bay form part of the boundary between the States of Connecticut and Rhode Island. Both states have identified water quality impairments within these waters related to nutrients (insufficient oxygen) and bacteria. Studies of the eutrophication potential of Long Island Sound embayments have identified that the Pawcatuck...
