As
part of the Bering Strait project funded by
NSF-AON (Arctic Observing Network), in
September 2019 a team of five US scientists
undertook a ~ 11 day cruise in the Bering
Strait and southern Chukchi Sea region on the
US vessel Norseman II, operated by Norseman
Maritime Charters.
The primary goals of the expedition were:
1) recovery of 3 moorings carrying physical
oceanographic (Woodgate and Peralta-Ferrriz)
and whale acoustic (Stafford) instrumentation.
These moorings were deployed in the Bering
Strait region in 2018 from the Norseman II.
The funding for the physical oceanographic
components of these moorings comes from
NSF-AON.
2) deployment of 3 moorings in the Bering
Strait region, carrying physical oceanographic
(Woodgate and Peralta-Ferriz) and whale
acoustic (Stafford) instrumentation. The
funding for the physical oceanographic
components of these moorings comes from
NSF-AON.
3) accompanying CTD sections (without water
sampling).
4) collection of accompanying ship's underway
data (surface water properties, ADCP,
meteorological data).
The cruise loaded and offloaded in Nome,
Alaska.
Key Statistics: 3 moorings recovered, 3
moorings deployed, 438 CTD casts on 22 CTD
lines
