Arctic Regional Ocean Observing System (Arctic ROOS)

The Arctic Regional Ocean Observing System (Arctic ROOS) web site presents daily updated maps and plots of the arctic sea ice from satellite observations and ice forecasts from ice-ocean modeling. The presentations are prepared by Nansen Environmental and Remote Sensing Center and other members of the Arctic ROOS. Arctic ROOS will promote, develop and maintain operational monitoring and forecasting of ocean circulation, water masses, ocean surface conditions, sea ice and biological/chemical constituents.

The annual minimum of arctic sea ice occurs in September, and present data shows that the sea ice minimum in 2008 will be very close to the 2007 minimum, which set a record for the lowest ice area since satellite observations began in 1979. The daily images are available at
