  • German icebreaker RV Polarstern, a hulking ship will set out for the Arctic packed with supplies and scientific equipment for a year-long mission to explore the planet’s frigid far north.
  • The icebreaker will be the base for scientists from 17 nations studying the impact of climate change on the Arctic and how it could affect the rest of the world.

  • Scientists plan to sail the ship into the Arctic Ocean, anchor it to a large piece of sea ice and allow the water to freeze around them, effectively trapping themselves in the vast sheet of white that forms over the North Pole each winter.
    • The organizers say that the project is unprecedented in scale and ambition.
  • The MOSAiC mission, which stands for Multidisciplinary drifting Observatory for the Study of Arctic Climate, comes about 125 years after Norwegian explorer Fridtjof Nansen first managed to seal his wooden expedition ship, Fram, into the ice during a three-year expedition to the North Pole.
  • As temperatures drop and the days get shorter, they’ll race against time to build temporary winter research camps on the ice, allowing them to perform tests that wouldn’t be possible at other times of the year or by satellite sensing.
  • Scientists from United States, China, Russia and other countries will be rotating every two months as other icebreakers bring fresh supplies
  • The mission has received funding from U.S. institutions such as the National Science Foundation, the Department of Energy, the National Oceanic and Atmospheric Administration, and NASA.

Significance

  • By combining measurements on the ice with data collected from satellites, scientists hope to improve the increasingly sophisticated computer models for weather and climate predictions.
    • Scientists now believe the cold cap that forms each year is key to regulating weather patterns and temperatures across the Northern Hemisphere. Anything that disrupts the Arctic will be felt further south
