sea ice (2006)

sea ice (2006)

Sea ice forms when the ocean freezes in the winter. Depending on wind conditions and how fast the ice forms the newly generated ice has different shapes. Under moderate wind conditions the new ice is created by forming these circular shapes, which is called pancake ice. If enough pancake ice is formed, wind can blow the ice together into dense fields.

Amundsen Sea Ice (2006)

Amundsen Sea Ice (2006)

Sea ice forms when the ocean freezes in the winter. Under calm wind conditions the water freezes in sheets (Nilas). These sheets can move over and into each. Sometimes like here in the Amundsen Sea, new snow covers the sea ice.

Illustration of Godzilla hydrothermal edifice (1993)

Illustration of Godzilla hydrothermal edifice (1993)

Typical actively-venting sulfide mineral edifice in the High-Rise vent field of the Juan de Fuca Ridge. The 45 m-high edifice, named Godzilla, was discovered and mapped in 1991. For scale the submersible Alvin, shown to the left of the edifice, is 6 m long. Courtesy of V. Robigou, Ocean et Terra Studio.

Sedimentological processes and prediction in deltas (2009)

Sedimentological processes and prediction in deltas (2009)

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., 2009].
