STRAIT 2017 MOORING CRUISE OVERVIEW
BERING STRAIT 2017 CRUISE MAP
As part of the Bering Strait project funded by NSF-AON (Arctic Observing Network), in July 2017 a team of US scientists undertook a ~ 8 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 2016 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).
5) deployment of an autonomous glider in the southern Chukchi Sea (Statscewich).
6) deployment of two IABP (International Arctic Buoy Program) drifters (Rigor).
Due to mostly reasonably calm, clear weather, all moorings were safely recovered and redeployed, and a total of 342 CTD casts (on 19 lines) were taken. For full details, and preliminary results, see:

Arrows indicate direction of travel (on inset below, blue during mooring operations before CTD survey, green during CTD survey). Depth contours every 10m from the International Bathymetric Chart of the Arctic Ocean (IBCAO) [Jakobsson et al., 2000]. Lower panels give detail of strait region at the start (left) and end (right) of the cruise. See cruise report for daily detail.
PRELIMINARY INTERANNUAL RESULTS (as pdf)
Post-cruise calibrations and subsequent further data quality control are still to be performed, however, preliminary data suggest some remarkable changes in the strait in the last year, viz:
