In 1999, the USGS, in partnership with the South Carolina Sea Grant Consortium, began a study to investigate processes affecting shoreline change along the northern coast of...

Cape Cod Bay, lying on the Massachusetts coast partly enclosed by Cape Cod, is in a glaciated region of low relief. Coarse sediments generally occur in areas exposed to wave and...

This data set shows the distribution of surficial sediments offshore of northern and eastern Cape Cod, Massachusetts. This interpretation is based on data collected with a...

The objective of this study is to quantify population, community, and ecosystem level changes as a result of salmon recolonization of the Cedar River, WA above Landsburg Dam....

The sediment data presented in this data layer were from a geochemical study sited in Great Bay Estuary, New Hampshire. The analog data were originally converted into digital...

This data set includes the locations, identifiers, grain-size data and(or) textural descriptions of surficial sediments collected at 89 stations on topographic and backscatter...

As part of the hydrodynamic and sediment transport investigations in San Pablo Bay and China Camp Marsh, California, particle size distributions of bed sediments were measured...

Data include burrowing behavior of juvenile freshwater mussels (Lampsilis siliquoidea); Villosa constricta; Megalonaias nervosa; Villosa iris; Lampsilis powellii; and Anodonta...

The U.S. Geological Survey (USGS), in cooperation with the Connecticut Department of Environmental Protection and National Oceanic and Atmospheric Administration (NOAA), is...

Geophysical and geological survey data were collected off Town Neck Beach in Sandwich, Massachusetts, in May and July 2016. Approximately 130 linear kilometers of subbottom...

The coastal dunes, beaches, and inner neritic zone of the Merrimack Embayment constitute a petrologic province. In addition to heavy mineral analyses, grain size statistics were...

Geochemical behavior of the upper 70 cm of permeable reef flat sediments on Checker Reef, Oahu, Hawaii was examined using spatial and temporal changes in pore water dissolved...

Accurate data and maps of sea-floor geology are important first steps toward protecting habitat, delineating marine resources, and assessing environmental changes due to natural...

This data release comprises three tables containing cosmogenic beryllium-10 and aluminum-26 concentrations and related data from samples collected at four sites along the...

As part of the hydrodynamic and sediment transport investigations in San Pablo Bay and China Camp Marsh, California, particle size distributions of bed sediments were measured...

This dataset consists of survey data from bank profiles surveyed June 12 and June 24-26, 2013 at the edge of the active braid plain of Exit Creek, a stream draining Exit Glacier...

A study was made of the composition, grain-size distribution, and organic content of grab samples collected from Boston Harbor. In general, the coarsest mean sizes occur in the...
