In February of 2021, scientists from the USGS Woods Hole Coastal and Marine Science Center and Woods Hole Oceanographic Institution (WHOI) conducted near-shore bathymetric surveys on Cape Cod National Seashore. 

In February of 2021, scientists from the USGS Woods Hole Coastal and Marine Science Center and Woods Hole Oceanographic Institution (WHOI) conducted near-shore bathymetric surveys on Cape Cod National Seashore. Bathymetry is the study of underwater depth of ocean floors or lake floors.

WHOI/MIT PhD. Student, Sheron Luk, analyses sediment carbon on an Elemental Analyzer at Woods Hole Coastal and Marine Science Center.

Composite results from the Alaska marine margin monograph chapter, modified from the figure by C. Ruppel and P. Hart. Red, yellow, and green lines indicate locations of seismic data lacking gas hydrate features, possibly having bottom simulating reflections (BSRs) indicative of gas hydrates, and definitely hosting BSRs, respectively.

Lab Manager, Adrian Mann, analyzes pore water samples on an Ion Chromatograph.

USGS samples water within wetlands to understand which environmental drivers impact carbon cycle and sediment accretion. Here USGS staff (Jennifer O'Keefe Suttles) pumps water from at Phragmites wetland, Mashpee, MA, to analyze at the Woods Hole Coastal and Marine Science Center Environmental Geochemistry lab.

A glass micromodel (upper left) allows fluid flow through gaps between solid cylinders (gap size of 100 micrometers is shown in the upper-right image). Injecting fine-grained materials allows us to characterize the conditions in which clogs occur, as they have done in the upper- and lower-right pictures.

The USGS Gas Hydrates Project manages the standalone Hydrate Pressure Core Analysis Laboratory (HyPrCAL) at the Woods Hole Coastal and Marine Science Center (WHCMSC) to study hydrate-bearing sediments in support of energy resources a

Hurricane Sandy (2012) modeling: Modeling can reveal the contributions from underlying processes individually. These images show contribution from offshore surge (change in water level) and offshore waves to maximum water levels (in meters) within a bay during a coastal storm.

The USGS Gas Hydrates Project develops and tests new tools to address the critical knowledge gaps identified as scientists analyze hydrate-bearing pressure cores recovered during field programs.

The USGS will be using an autonomous surf vehicle, built by Peter Traykovski of WHOI, to map the bathymetry of the Pea Island DUNEX Experiment Site. 

The autonomous surf vehicle, built and controlled remotely  by Peter Traykovski of WHOI, is used to map the bathymetry of the Pea Island DUNEX Experiment Site.

Robert Scharping, a post-doctoral fellow jointly appointed by the USGS and the Woods Hole Oceanographic Institution (WHOI) measures water chemistry 40’ underwater and underground in Double Keyhole Cave near the coastline of Tampa Bay Florida.

The study used 12-foot-tall static chambers to enclose Phragmites vegetation and assess how much methane and carbon dioxide move in and out of the ecosystem across the salinity gradient.
