As
part of the Bering Strait project funded by
NSF-AON (Arctic Observing Network), in
September 2020, the research vessel Norseman
II, of Support Vessels of Alaska, Inc.,
undertook an 11 day cruise in the Bering
Strait and southern Chukchi Sea region.
Due to the Covid pandemic, no scientists
joined the cruise, but instead the science
work of the cruise was directed from land
using high speed internet links (including
live video) for communications.
The primary goals of the expedition were:
1) deployment of 4 moorings carrying
physical oceanographic (Woodgate and
Peralta-Ferrriz) and whale acoustic (Stafford,
Berchok) instrumentation. The funding for the
physical oceanographic components of these
moorings comes from NSF-AON. The Berchok
mooring is funded by NOAA.
2) deployment of 1 glider
(Statscewich, Danielson, Baumgartner)
3) an underway survey (measuring
surface water properties, ADCP, meteorological
data) of the Bering Strait and southern
Chukchi Sea region.
The cruise onloaded in Homer (1st Sept 2020),
passed Nome (8th Sept 2020), and ended in Nome
(18th September 2020), with equipment offload
scheduled for Homer in Oct/November 2020.
