More than 500 participants from over 16 nations have spent a year in the Arctic ice collecting important data on the Arctic climate system. From September 2019 through October 2020, the icebreaker RV Polarstern drifted across the central Arctic near the North Pole frozen in sea ice during one of the most extensive Arctic research expeditions ever conducted. You can learn more about the MOSAiC (Multidisciplinary drifting Observatory for the Study of Arctic Climate) research expedition at! Bring MOSAiC into your classroom with Data Puzzles, 360-degree virtual experiences, the Polar Planetarium field trip, classroom curriculumand more learning resources. Experience MOSAiC all around you with two planetarium films featuring footage captured by videographers on the Polarstern now showing at Fiske Planetarium in Boulder (also available to view in 2D).

MOSAiC Digital Resources

An international group of educators, photographers, cinematographers, and scientists have teamed together to bring the MOSAiC expedition to everyone and anyone fascinated by the Arctic, including K-16 students across the globe. Bookmark this site and check in regularly for curricula, videos, and other updates from the ship.

MOSAiC MOOC: Frozen in Ice

“Frozen in the Ice: Exploring the Arctic” MOOC, which is about the extraordinary MOSAiC Arctic research mission that has frozen an icebreaker into the Arctic Ocean, where it will drift for 13 months (

In this course, you’ll hear directly from more than three dozen MOSAiC scientists and Arctic experts as they summarize the core of their research, what types of data they collect during MOSAiC on the ice, under the sea, and in the air, and describe why this expedition is so key for increasing our understanding of the Arctic and global climate systems.

“Frozen in the Ice: Exploring the Arctic” is also offered through Coursera
