MOSAiC - Multidisciplinary drifting Observatory for the Study of Arctic Climate

Further map and data products around sea ice during the MOSAiC expedition can be found here.


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 Ticker

Dear sea ice fans!

Now that 2020 has begun, the meereisportal.de will be resuming its regular Sea Ice Ticker reports from the MOSAiC expedition, and we would like to begin by wishing all our readers a very happy new year! 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!

After two-and-a-half years, the adopt-a-buoy project draws to a close

13 January 2020
The ‘last survivor’ from the adopt-a-buoy project was the ice mass balance buoy (2018M11), which continued transmitting until 27 November 2019, when it, too, was lost in the marginal ice zone. In the course of 1 year, 9 months and 9 days, the buoy had traversed the Weddell Sea and covered a distance of more than 8200 km. To give the children a better idea of what this distance means, in the buoy biographies the sea-ice physicist described it as “the distance from Berlin to the North Pole – and back!”.

Live stream from on board: The latest radar images of the ship’s surroundings

15 December 2019
Ship navigation at sea and especially in ice -covered oceans is facilitated by radar systems. In this regard, RV Polarstern is equipped with several marine radar systems, which are used to identify other ships and obstacles. When moving through pack ice, these systems offer information on the presence of channels or massively deformed pack ice. On seaiceportal.de we now show daily updated video sequences of the RV Polarstern ship radar images. Read more here...

GIS

29 November 2019
When it comes to the use and interpretation of climate data, combining products is an important step, because doing so allows us to establish visual connections between diverse parameters or observational scales. And the WebGIS app recently added to the data portal at meereisportal.de makes that possible. “The new WebGIS application allows us to share the diverse range of data at meeresportal.de with users in an easily accessible format, and to present the wealth of information in a different way,” explains Dr Annekathrin Jäkel, the data expert responsible for the app at meereisportal.de.
