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 meereisportal.de we accompanied the MOSAiC expedition with sea-ice-related information and detailed ice maps, and reported on the initial findings. In the course of ten DriftStories, once a month we showcased experts from the expedition’s ICE Team and explored the backgrounds of their research areas. You can continue to find all DriftStories, which offer a closer look at the sea-ice-related work done on site and the relevance of their research for the MOSAIC expedition as a whole, here.

And now, we hope you’ll enjoy reading the tenth and final DriftStory, entitled "A reunion at the outlet of the Arctic".

Sea Ice Ticker

Dear sea ice fans!

Since August 2019, meereisportal.de has provided regular coverage of the MOSAiC expedition in the form of the Sea Ice Ticker. Though the main focus of the Ticker texts was on fieldwork conducted on all aspects of sea ice, we also explored other topics, especially with regard to new developments, milestones and findings in the context of the MOSAiC drift experiment. The Sea Ice Ticker texts were released once a week, and this will be the last instalment before the MOSAiC expedition comes to an end on Monday, 12 October. We hope you enjoyed reading the texts and found all the information you needed on this unprecedented expedition – and we hope you’ll continued to visit meereisportal.de for all the latest news on sea ice!!

Bert and Pipa – the new social media mascots on meereisportal.de

9 October 2020
In 2016 we began a collaboration with the degree programme in Media and Communication Studies at the FU Berlin. One example selected for the collaboration: the information and data platform meereisportal.de. Ever since, students have worked on the social media channels of meereisportal.de in connection with courses at the FU Berlin. Another idea that soon emerged: using a polar bear and penguin as representatives of the two polar regions. The two mascots’ look was iteratively refined by the students, and adapted for their future use online. Read on...

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.
