Meet USGS' newest laboratory!

Proven under Pressure: USGS Advances Capabilities for High-Pressure Seafloor Samples Containing Gas Hydrate

The pressure cores will be analyzed in the newly-inaugurated USGS Hydrate Pressure Core Analysis Laboratory (HyPrCAL)at the Woods Hole Coastal and Marine Science Center. This facility is the first in the U.S. to be designed for and dedicated to the analysis of pressure cores. USGS scientists will use HyPrCAL to conduct geotechnical, electrical, and hydraulic measurements on hydrate-bearing pressure cores and to complete benchtop testing of methane production from gas hydrates.

The USGS Gas Hydrates Project is a leading international gas hydrates research program focused on energy resource, environmental, and geohazard issues.

USGS releases 2016 lidar-derived topobathymetric data for Assateague Island, Maryland and Virginia

The USGS has released 2016 lidar-derived topobathymetric data for Assateague Island, Maryland and Virginia. The survey, flown in September 2016, post-Hurricane Hermine (USGS field activity number [FAN] 16CNT03: https://coastal.er.usgs.gov/data-release/doi-F7NP22NH/), was a repeat effort of the survey flown post-Hurricane Joaquin in November 2015 (FAN 2015-344-FA: https://coastal.er.usgs.gov/data-release/doi-F70P0X4G/). The CMGP's National Assessment of Coastal Change Hazards project uses lidar-derived data to quantify the vulnerability of shorelines to coastal change hazards, such as severe storms, sea-level rise, and shoreline erosion and retreat.
