Data products and information around sea ice during the MOSAiC expedition.

It could be the largest-scale Arctic research expedition of all time: in September 2019 the German research icebreaker Polarstern will depart from Tromsø, Norway and, once it has reached its destination, will spend the next year drifting through the Arctic Ocean, trapped in the ice. A total of 600 people from 19 countries, who will be supplied by other icebreakers and aircraft, will participate in the expedition – and several times that number of researchers will subsequently use the data gathered to take climate and ecosystem research to the next level. The mission will be spearheaded by the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI). More information about the expedtion here.


 
 

Sea-ice extents recalculated, starting from 2018!

12 September 2020
Once the errors in our processing routine for calculating the sea-ice extent had been identified and corrected, all time series since 1 May 2018 were recalculated, double-checked and then posted on the website again, from 11 September. Older time series are unaffected by the correction. Comparing the results of different algorithms and questioning the accuracy of their results is part of the scientific process, and of quality control. This news informs you, how satellite algorithms work, why they have to be updated from time to time and why we have to update our data. The updated data and graphs are now online. Read more here…

DriftStories from the 2019/2020 MOSAiC expedition through the Central Arctic

With the DriftStories, once a month we’ll introduce a member of the ICE Team and share insights into the background of their research area. Together with the weekly Sea Ice Ticker, these stories will present the sea-ice-related work being done on site in more detail, and help readers understand the role of sea-ice research within the context of the MOSAiC expedition as a whole. We hope you enjoy reading them!

Sea Ice Ticker

Dear sea ice fans!

Since beginning of 2020 the meereisportal.de reports in its regular Sea Ice Ticker from the MOSAiC expedition. The Sea Ice Ticker will continue to chiefly focus on sea-ice-related activities, but will also address other topics when there are exciting events or findings to report from the MOSAiC drift experiment. The Ticker will be released on a weekly basis. We hope you enjoy reading the new posts and the exclusive updates on the expedition’s progress!

Sea Ice Ticker No. 55, 25 September 2020: Data for MOSAiC’s second year

Arctic sea-ice extent on an extremely low course

17 September 2020
After the summer months June and July 2020 had yielded minimum values in the 42-year time series of sea-ice extent, the trend continued in September, underscoring the importance of Arctic warming as an early-warning system for global climate change. The all-time lowest mean September extent, at 3.49 million km², was reached in 2012, followed by the years 2019 and 2007. The mean value in August was 5.03 million km², making it the third-lowest extent (after 2012 and 2019) since 1979. he Pan-Arctic August Outlook median forecast value for September 2020 sea-ice extent is 4.30 million square kilometers, with quartile values of 4.1 and 4.5 million square kilometers.
