Surface sediment samples collected from the United States Coast Guard Cutter Healy (HLY1801), Northern Bering Sea to Chukchi Sea (2018)

The Pacific sector of the Arctic Ocean is experiencing major reductions in seasonal sea ice extent and increases in sea surface temperatures. One of the key uncertainties in this region is how the marine ecosystem will respond to seasonal shifts in the timing of spring sea ice retreat and/or delays...
