Estuarine bed-sediment-quality data collected in New Jersey and New York after Hurricane Sandy, 2013 Estuarine bed-sediment-quality data collected in New Jersey and New York after Hurricane Sandy, 2013

This report describes a reconnaissance study of estuarine bed-sediment quality conducted June–October 2013 in New Jersey and New York after Hurricane Sandy in October 2012 to assess the extent of contamination and the potential long-term human and ecological impacts of the storm. The study, funded through the Disaster Relief Appropriations Act of 2013 (PL 113-2), was conducted by the U.S...

Data to Assess Nitrogen Export from Forested Watersheds in and near the Long Island Sound Basin with Weighted Regressions on Time, Discharge, and Season (WRTDS) Data to Assess Nitrogen Export from Forested Watersheds in and near the Long Island Sound Basin with Weighted Regressions on Time, Discharge, and Season (WRTDS)

The U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency's Long Island Sound Study (https://longislandsoundstudy.net), characterized nitrogen export from forested watersheds and whether nitrogen loading has been increasing or decreasing to help inform Long Island Sound management strategies. The Weighted Regressions on Time, Discharge, and Season (WRTDS...

Location, sampling methods and field conditions of response-mode soil and sediment sampling stations sampled, Sediment-Bound Contaminant Resiliency and Response Strategy pilot study, northeastern United States, 2015 Location, sampling methods and field conditions of response-mode soil and sediment sampling stations sampled, Sediment-Bound Contaminant Resiliency and Response Strategy pilot study, northeastern United States, 2015

Coastal communities are uniquely vulnerable to sea-level rise (SLR) and severe storms such as hurricanes. These events enhance the dispersion and concentration of natural and anthropogenic chemicals and pathogenic microorganisms that could adversely affect the health and resilience of coastal communities and ecosystems in coming years. The U.S. Geological Survey has developed the...
