Explanation:

The Arctic is a key area of global climate change, with warming rates exceeding twice the global average.
Many processes in the Arctic climate system are poorly represented in climate models because they are not sufficiently understood.
Understanding of Arctic climate processes is limited by a lack of year round observations in the central Arctic.

The Multidisciplinary drifting Observatory for the study of Arctic climate (MOSAiC) will be the first year-round expedition into the central Arctic exploring the Arctic climate system.
The project with a total budget exceeding 60 Million € has been designed by an international consortium of leading polar research institutions under the umbrella of the International Arctic Science Committee (IASC).
The results of MOSAiC will contribute to enhance understanding of the regional and global consequences of Arctic climate change and sea-ice loss and improve weather and climate predictions.
As such it will support safer maritime and offshore operations, contribute to an improved scientific basis for future fishery and traffic along northern sea routes, increase coastal- community resilience, and support science-informed decision-making and policy development.
