MOSAiC is the world’s largest and most comprehensive expedition to the central Arctic Ocean. Five UAF researchers will take part, embarking on multiple legs of a year-long journey onboard icebreaker RV Polarstern locked in the frozen sea ice and set to drift past the north pole.
The unprecedented Multidisciplinary Drifting Observatory for the Study of Arctic Climate will capture the closest look ever at the Arctic to understand why it is warming faster than any other region on the planet. Hundreds of scientists from around the world will gather data related to the ocean, sea ice, snow and atmosphere from a chemical, physical and biological point of view.
UAF’s team will write a weekly blog, providing a rare glimpse into life as a scientist conducting research in one of the most extreme and unique environments on earth. An environment whose changes, although poorly understood, are already impacting sea level rise, storminess, ocean and atmospheric warming at lower latitudes.
The UAF MOSAiC team is focused on gaining a more complete picture of what’s happening in the Arctic Ocean where the ocean, sea ice and atmosphere meet.
In the Arctic, this interface is important because it is where gases and nutrients are transferred between the ocean and ice, and the ice and the atmosphere. Macronutrients like nitrate and phosphate are used by phytoplankton and sea ice algae to grow and ultimately feed the rest of the food web. Micronutrients, like iron and other metals, are also essential elements required by the ocean.
MOSAiC leaves Tromso, Norway September 20, 2019. IARC's Rob Rember and Marc Oggier will be on leg one of the expedition (September 2019 to January 2020), they'll send dispatches from aboard ship—we'll display the posts on this page.
