BERING
STRAIT 2013 CRUISE MAP |
As
part of the joint US-Russian RUSALCA (Russian
US Long-term Census of the Arctic Ocean)
Program and the Bering Strait AON (Arctic
Observing Network) and a related ONR effort
for measuring the Bering Strait throughflow, a
team of US scientists undertook a 7 day cruise
in the Bering Strait and southern Chukchi Sea
region in July 2013 on the US vessel Norseman
II, operated by Norseman Maritime Charters,
and loading and off-loading in Nome, Alaska.
The major objective of the cruise was mooring work in the Bering Strait region, i.e., the recovery and redeployment of moorings (5 recoveries, 3 deployments), a joint project by the University of Washington (UW), and the University of Alaska, Fairbanks (UAF). The mooring recoveries are supported by an NSF-OPP AON grant(PIs: Woodgate, Weingartner, Whitledge and Lindsay), and the mooring deployments are supported by an ONR grant (PI: Woodgate). The moorings measure water velocity,temperature, salinity, ice motion, ice thickness (crudely) and some bio-optics and whale acoustics. Figure:
