Researchers deploying a corer in Lake Enriquillo.

Jessica Rodysill (Reston) and Hunter Wilcox (SPCMSC) deploying a corer in Lake Enriquillo. The scientists will use the cores to construct precipitation changes in Dominican Republic over the late Holocene (~5000 years ago to present) time period.

Coring in Lake Enriquillo, Dominican Republic

This is one of three 4–5 meter long sediment cores recovered from the deepest part of Lago Enriquillo (95 feet water depth). This sediment core most likely represents the late Holocene (~5000 years ago to present), and the scientists will use it to construct precipitation changes in Dominican Republic over that time period.

SPMSC scientist Lauren Toth conducts a photographic survey of the reef

SPMSC scientist Lauren Toth conducts a photographic survey of Porter Patch reef off Key Largo, one of the sites that has been surveyed as part of FWRI’s Coral Reef Ecosystem Monitoring project since 1996. The modern reef surveys will be compared to historic surveys to determine how much structural complexity the reefs of the Florida Keys have lost over the past two decades

Giving a Tour of USGS Science Center

On March 25th, 2019, ocean engineer Rob Wyland of the Pacific Coastal and Marine Science Center gave a tour and demonstration to roughly a dozen students from the engineering class he teaches at Cabrillo College, a local community college. Wyland showed students many of the tools and materials he uses on the

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.

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

Data visualization with scaled options applied

Data visualization with (A) fixed and (B) scaled options applied. Examples of NSM and SCE are also displayed (C and D respectively). The data itself has not changed – only the scaling and statistic selected through the DSAS Data Visualization tool.

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
