Explaining Cold and Fresh Southern Polar Ocean Surface Waters
Global climate models do not reproduce observed trends of the Southern polar ocean surface, but an increase in wind-transported sea ice that melts and inhibits mixing may account for the disparity.

Arctic Coast Erosion Linked to Large-Scale Climate Variability
Changes in rates of Arctic coastal erosion detected from multi-decadal measurements are attributed to the shorter duration in the winter sea ice coverage and large-scale changes in the wind patterns.
