Fact Sheet 2011–3015
Recent U.S. Geological Survey (USGS) climate studies in the northeastern
United States have shown substantial evidence of climate-related changes during the
last 100 years, including earlier snowmelt runoff, decreasing occurrence of river ice,
and decreasing winter snowpack. These studies related to climate change are being
expanded to include investigation of coastal wetlands that might be at risk from sealevel
rise. Coastal wetlands, particularly salt marshes, are important ecosystems that
provide wildlife nursery and breeding habitat, migratory bird habitat, water quality
enhancement, and shoreline erosion control. The USGS is investigating salt marshes
