STRAIT 2022 MOORING CRUISE OVERVIEW
BERING STRAIT 2022 CRUISE MAP
As part of the Bering Strait project funded by NSF-AON (Arctic Observing Network), in September 2022 a team of US scientists undertook a ~ 11 day cruise in the Bering Strait and southern Chukchi Sea region on the US vessel Norseman II, operated by Support Vessels of Alaska, Inc..
The primary goals of the expedition were:
1) recovery of 3 moorings carrying physical oceanographic (Woodgate & Peralta Ferriz) and whale acoustic (Stafford) instrumentation. These moorings were deployed in the Bering Strait region in 2021 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 and biogeochemical oceanographic (Woodgate & Peralta-Ferriz) and whale acoustic (Stafford) instrumentation. The funding for the physical and biogeochemical oceanographic components of these moorings comes from NSF-AON.
3) a set of CTD sections studying water properties in the region, with some sampling for nutrients and salinities (Woodgate & Peralta-Ferriz),
4) collection of trace metal/nutrient water samples using a pumped system at selected CTD casts (Jensen)
5) collection of accompanying ship’s underway data, viz. surface water temperature and salinity, ADCP velocity data and meteorological data (Woodgate & Peralta-Ferriz),
6) underway marine mammal survey (Stafford & Laidre).
The cruise loaded and offloaded gear and people in Nome, Alaska.
- 2 moorings recovered,
- 3 moorings deployed,
- 111 CTD casts on 4 CTD lines, with 169 nutrient samples and 20 salinity samples - trace metal/nutrient water samples taken on 35 stations
