Abstract
Oceanographic observations from the Eurasian Basin north of Svalbard collected between
January and June 2015 from the N‐ICE2015 drifting expedition are presented. The unique
winter observations are a key contribution to existing climatologies of the Arctic
Ocean, and show a ∼100 m deep winter mixed layer likely due to high sea ice growth
rates in local leads. Current observations for the upper ∼200 m show mostly a barotropic
flow, enhanced over the shallow Yermak Plateau. The two branches of inflowing Atlantic
Water are partly captured, confirming that the outer Yermak Branch follows the perimeter
of the plateau, and the inner Svalbard Branch the coast. Atlantic Water observed to
be warmer and shallower than in the climatology, is found directly below the mixed
layer down to 800 m depth, and is warmest along the slope, while its properties inside
the basin are quite homogeneous. From late May onwards, the drift was continually
close to the ice edge and a thinner surface mixed layer and shallower Atlantic Water
coincided with significant sea ice melt being observed.
