AWI team reaches the North Pole
16 August 2018
It may come as a surprise, but due to this year’s ice conditions, the Swedish icebreaker Oden had serious difficulties penetrating to the North Pole. The Oden first hit the edge of the ice at 82 °N. “We’re very curious to see how the dense ice in the region has affected the ice thickness and the algae livening in the ice,” reports Christian Katlein from on board the icebreaker.

The days are getting longer, the seasonal sea-ice extent is still on the rise – the status quo of Antarctic sea ice
7 August 2018
The maximum sea-ice extent around the Antarctic continent has by no means already been reached. Nevertheless, over the past few months the area of sea ice has grown by an average of 0.1 million km2 per day, a higher rate than has been observed in the past several years.

Winter 2017/18 sea ice thickness analysis with observations from CryoSat-2
21 June 2018
CryoSat-2, a radar altimeter satellite of the European Space Agency (ESA), had its eighth birthday on April 8, 2018. Observations from CryoSat-2 add vital information on sea ice thickness to other satellite observations, such as sea ice concentration, drift and extent. Read more here about latest results from the these measurements.
Data portal expands its services for sea-ice drift
15 March 2018
‘The sea-ice drift data offers researchers the chance to more accurately investigate the loss of sea ice in the Arctic by allowing them to view not only the ice concentration and thickness, but also horizontal ice transport,’ explains Dr Hiroshi Sumata, a sea-ice physicist at the AWI and head of the project for calculating sea-ice drift uncertainties.

Sea-ice concentration in the Antarctic reaches its minimum
12. März 2018
While record high temperatures for winter were being measured in the Arctic and the maximum winter sea-ice extent was reached, the sea-ice extent in the Antarctic reached its summer minimum for this year. The especially low amount of Antarctic sea-ice cover this summer meant extremely favourable conditions for the research icebreaker RV Polarstern, whose route took her to the southern Weddell Sea this year.
Sea ice extent on record low: In the Arctic it is too warm and too wet
2 March 2018
Usually, at the North Pole the sun doesn’t rise before 20th March and it is the coldest time of the year. But this year, February was extraordinarily warm. Analyses of satellite and station data indicate that very warm air has been advected towards the Arctic, which allowed temperatures to rise until the freezing point. Read more here...
