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.

A WHCMSC and WHOI team recovered six intermediate period ocean bottom seismographs from the continental slope offshore New England in Georges Bank. The instruments had been deployed for about ten months to record background, ambient seismic noise.

Gas hydrate (orange material) and gas bubbles near the seafloor in the northern Gulf of Mexico. As the methane bubbles are emitted, a rind of gas hydrate immediately forms around some of them. If more bubbles continue to feed from below, gas hydrate forms.

Coastal wetland ecosystems in Jamaica Bay, New York, provide important ecosystem services along the highly urbanized Atlantic coast.

This model shows what Dauphin Island, Alabama, may look like under moderate storms but with increasing rates of sea level rise (Passeri and others, 2018).

Storm and sea level rise scenario models, like the one shown here, can be used to explore the future. This model shows what Dauphin Island may look like 10 years from now if storms become stronger and more frequent (Passeri and others, 2018).

The Herring River in Wellfleet, MA is a tidally-restricted estuary system. Management options including potential restoration of unrestricted tidal flows require an understanding of pre-restoration sediment conditions

 Major ions such as Sulfate and Chloride are measured with an Ion Chromatograph

A well sensor continuously monitors salinity, temperature, and water level in a salt marsh, Cape Cod, MA

Meagan Gonneea checks on instruments at a tidal creek in Great Pond, Falmouth, MA. Daily tides drive exchange between coastal wetlands and adjacent estuaries. Here we have instrumented a tidal channel to measure those fluxes over a tidal cycle. When the marsh floods, material is imported from the estuary.

Gamma well detectors are used to determine the ages of sediments based on activities of natural and anthropogenic radionuclides

Dissolved inorganic carbon (DIC) in water samples is measured with a UIC, Inc. Coulometer
