Bedrock outcrop in New Hampshire

The Concept of Geologic Carbon Sequestration
The use of carbon dioxide (CO2) injection for enhanced oil recovery (EOR) can prolong the productivity of many oil reservoirs and increase the U.S. hydrocarbon recoverable resource volume.

Acoustic backscatter and bathymetry maps
Map showing Holocene (modern) sediment thickness
Map showing Holocene (modern) sediment thickness in meters overlain on bathymetry. Regional bathymetric contours are in meters. Note the shoreface-attached sand ridges west of Watch Hill.

Numerical model grids
Numerical model grids showing downscaling from larger regional grid (far right) to more refined coastal grid (left). Colors are bathymetry (m).

Deployment period storm analysis.
Deployment period storm analysis. (A) significant wave height (red line) and wind speed and direction (arrows). Shading represents storm type (blue = cold front, red = warm front, yellow = low-pressure). (B) Vertical profiles of suspended-sediment concentration. (C) Cumulative along-shore and cross-shore sediment flux.

Example of a rip current experiment.
Example of a rip current experiment. Colors show bathymetry and arrows show velocity vectors after 1 h of model simulation. Similar to results in Kumar and others, 2012.

Worldwide distribution of observed and inferred gas hydrates
Worldwide distribution of observed and inferred gas hydrates in marine and permafrost-associated settings that have been the subject of drilling programs. The color coding refers to the primary sediment type in each location and therefore designates the likely type of gas hydrate reservoir at each site.
