Surficial Geology Map of Nantucket and Marthas Vineyard, MA

Map showing the surficial geology from this study and Baldwin and others (2016) with equivalent onshore geology (adapted from Stone and DiGiacomo-Cohen, 2009). The areal extents over which offshore subsurface geologic units crop out at the sea floor were interpreted from seismic-reflection data.

Water Column and Seismic collage

3D Image of a multi-channel seismic (MCS) line showing gas (blue/green) migrating up through fractures in the subsurface, culminating in a 600 meter tall plume of methane gas in the water column that was captured using a Simrad EK60 split beam echo sounder.  Background bathymetry was downloaded from USGS Open-File Report 2012-1266 (

Sediment textures distribution from Nantucket and Marthas Vineyard, MA

The distribution of sediment textures within the study area. The bottom-type classification is from Barnhardt and others (1998) and is based on 16 sediment classes. The classification is based on four sediment units that include gravel (G), mud (M), rock (R), and sand (S). If the texture is greater than 90 percent, it is labeled with a single letter. If the composition of

Nantucket and Marthas Vineyard geologic illustrations

Geologic sections (C-C', D-D', and E-E') illustrating the general distributions and thicknesses of seismic stratigraphic units and major unconformities in the Martha’s Vineyard and Nantucket study areas. The geologic sections were produced from chirp seismic-reflection profile interpretations.The Uunconformity is a dashed line to denote that it is

Scientists collect data on Pelican Island, Alabama

In an effort spanning the Natural Hazards and Ecosystems Mission Areas, pilots from the Saint Petersburg and Woods Hole Coastal and Marine Science Centers collect imagery data using Unmanned Aerial System (UAS) while personnel from the Wetlands and Aquatic Research Center (WARC) conduct ground-based site surveys of Pelican Island, Alabama. These data are being combined to

Piping Plover Habitat, Cedar Island

The beach-dependent shorebirds project at the Woods Hole Coastal and Marine Science Center models current and future habitat availability for nesting shorebirds in an effort to map current and likely future habitat availability on a range of sites along the U.S. Atlantic coast. Sites include beaches with minimal human-presence, such Cedar Island shown here off of the
