Characterizing freshwater and nutrient fluxes to West Falmouth Harbor, Massachusetts

These data present oceanographic and water-quality observations made at 4 locations in West Falmouth Harbor and 3 in Buzzards Bay, Massachusetts. While both Buzzards Bay and West Falmouth Harbor are estuarine embayments, the input of freshwater on the eastern margin of Buzzards Bay is largely due to groundwater. In West Falmouth Harbor, the groundwater that seeps into the harbor is characterized by relatively high levels of nitrate, originating from the Falmouth Wastewater Treatment Plant. This high nitrate ...

Summary of Oceanographic and Water-Quality Measurements near the Blackwater National Wildlife Refuge, 2011

Suspended-sediment transport is a critical element governing the geomorphology of tidal marshes. Marshes rely both on organic material and inorganic sediment deposition to maintain their elevation relative to sea-level. In wetlands near the Blackwater National Wildlife Refuge, MD, portions of the salt marsh have been subsiding relative to sea level since the early 20th century. Other portions of the marsh have been successful at maintaining elevation. The USGS undertook measurements of suspended-sediment ...

Static Oceanographic Observations made by the USGS Coastal and Marine Geology Program at Martha's Vineyard Coastal Observatory, September and October 2011

The U.S. Geological Survey (USGS) obtained oceanographic measurements as part of the Office of Naval Research (ONR) Optics Acoustics and Stress In Situ (OASIS) Project. The objective of this work is to relate optical and acoustic properties of suspended particles as a function of particle size, concentration, and vertical distribution near the sea floor. In order to accomplish this task, a specially modified tripod allows vertical profiling near the sea floor by moving instruments up and down within 2 ...

Suspended-sediment concentration (SSC) and loss-on-ignition (LOI) data from water samples collected in 2014-15 by the U.S. Geological Survey in Chincoteague Bay, Maryland and Virginia

U.S. Geological Survey scientists and technical support staff measured oceanographic, water quality, seabed elevation change, and meteorological parameters in Chincoteague Bay, Maryland and Virginia, during the period of August 13, 2014 to July 14, 2015 as part of the Estuarine Physical Response (EPR) to Storms project (GS2-2D) supported by the Department of the Interior Hurricane Sandy Recovery program. These measurements provide time series and supplemental data to quantify the response and understand the ...
