Photomosaic of Crab Basin vent cluster at Mothra (2003)
Wed, 04/15/2009 - 14:47 — mgds
Mosaic of a diffusely venting, cockscomb array at Crab Basin. In 1998, the top 1.5 m of Gwenen (far left) was removed during the Edifice Rex expedition. By 2003, when this composite image was collected, a small bush of tubeworms had grown above the cut surface. Subhorizontal fractures within the chimney are lined with white bacterial mat. Twenty images from ROPOS Dive 725 were used in this mosaic, created by Mitchell Elend, University of Washington.

Mt. Fuji (2008)
Fri, 07/11/2008 - 11:51 — mgds
Mt. Fuji, the famous volcano and icon of Japan, is seen in the center of this image. Its last eruption was in 1708. The perfect symmetry it shows today hides a complex geologic history.

Sedimentological processes and prediction in deltas (2009)
Tue, 05/25/2010 - 13:43 — mgds
Application of scientific understanding of balances between sedimentation, production of accommodation space, and process transitions to the prediction of future changes expected for large, heavily populated, low-lying deltas. This schematized prediction of the lower Mississippi River below New Orleans shows the predicted new land (delta surface) that could be built over the next 100 years depending on sediment flux, sea level rise, and subsidence rate [from Kim, et al., 2009a based on Kim, et al., 2009b].
