STRAIT 2018 MOORING CRUISE OVERVIEW
BERING STRAIT 2018 CRUISE MAP
As part of the Bering Strait project funded by NSF-AON (Arctic Observing Network), in August 2018 a team of US scientists undertook a ~ 10 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-NSF) and whale acoustic (Stafford) instrumentation. These moorings were deployed in the Bering Strait region in 2017 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 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.
Due to a fortunate weather window in an otherwise very storm cruise, all moorings were safely recovered and redeployed early in the cruise. Storms greatly limited our ability to run CTD lines, however, a total of 142 CTD casts (on 7 lines) were eventually accomplished. For full details, and preliminary results, see:
