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.

Oblique aerial photographs of Ocracoke Island, NC, from May 6, 2008 (top, pre-storm) and August 30, 2011 (bottom, post-storm, acquired three days after landfall of Hurricane Irene). The yellow arrow in each image points to the same feature. Overwash deposits of sand extend over the road after the storm.

Bird's-eye view map of a section of the seafloor off southern California, made with depth data. The map shows a channel wall that has been cut by the San Diego Trough fault and moved about 20 meters. This feature is about 1,000 meters below sea level.

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.

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.
