Winds driving increase in Antarctic sea ice

Caption: Trends in Antarctic sea ice motion over the 19-year study period are shown by the arrows, in meters per second per year. The background colors show the change in northward ice speed, with reds being fastest and blues slowest. The image highlights the tremendous variability in wind-driven ice drift around the Antarctic continent.

Sea ice volume: Multi-year arctic sea ice reducing dramatically

A new study has noted a substantial decadal decline in the Arctic Multiyear ice cover. While ice extent has been shrinking, much of this is seasonal ice that reforms each winter and can grow with variable weather factors such as changes in temperature, wind, weather and ocean currents. A reduction in the thicker multiyear ice indicates a much greater impact and collapse of sea ice is evident.
