Impervious Surfaces: Long Island Sound Regional Impervious Surface Study

In this study conducted for the Long Island Sound Study National Estuary Program, CLEAR researchers used innovative remote sensing techniques to quantify impervious surfaces in the Connecticut and lower New York region from 1985 to 2002. Impervious surfaces like asphalt, rooftops and concrete are a reliable indicator of the impact of development on water resources.

Connecticut Lake Water Clarity Estimation from Multi-temporal Satellite Imagery

Protecting lake water quality is a major concern for local, regional, and state agencies as well as citizens and non‐profit organizations. Comprehensive water quality data are essential for improved management and policy decisions. It is, however, prohibitively expensive to monitor water quality for a significant number of lakes and ponds using conventional methods.

Threats to Tidal Marshes of the Lower Connecticut River – Phragmites australis

NRCA’s Teacher Professional Learning provides a 3-day professional development workshop for upper middle school and high school science teachers who teach in the Earth Sciences (via integrated or stand-alone courses). Participants will be immersed in relevant local and regional water resource issues and online mapping tools to study these issues further. The workshop will also offer curricular and technological resources that participants will use to design 5-7 modules on a Water and Sustainability Science unit underpinning particular Next Generation Science Standards’ Earth and Space Science Performance Expectations.
