// EXPLANATION FOR MISSING ICE DRIFT DURING SUMMER PERIOD ?>
The ice drift product will not be updated between May and September (both month inclusive), due to dubious quality during ice surface melt.

Monitoring of sea ice motion in the Arctic is an important research and development task, both from
climate and human activities perspectives. As part of the EUMETSAT OSI SAF (
www.osi-saf.org), we have been
developing an operational sea ice drift observing system, based on sequence of satellite images.
The examples displayed on the right are 48 hours motion fields. Each arrow in the map corresponds to
the magnitude and direction of the displacement of sea ice during 48 hours. Extreme weather systems
as well as ocean eddies are causing most of the rotation patterns. The displacement vectors are
automatically processed every day from pairs of images acquired by the Advanced Microwave Scanning
Radiometer (AMSR-E), a satellite sensor operated by NASA.
This product is operational since December 2009. Further information can be found here: http://osisaf.met.no
