This dataset contains water temperature, salinity, oxygen, fluorescence, and turbidity taken by CTD from the research vessel Norseman II in Bering Strait during the 2021 Bering Strait mooring cruise. The cruise was funded by the NSF-Arctic Observing Network grant: - PLR-1758565 (PIs: Woodgate and Peralta-Ferriz). The data are from a ~ 10 day cruise - on the US vessel Norseman II - from 7th-17th July 2021 - sailing from and to Nome, Alaska, USA - to the Bering Strait and southern Chukchi Sea. The cruise was also to service oceanographic moorings in the strait and those data are archived separately. A total of 276 casts were taken and are included in this archive. Water samples were taken for trace metals during this cruise using a separate pumping system (lead: Laramie Jensen). Stations were taken in US waters near mooring locations and on sections in the Bering Strait and southern Chukchi Sea. See cruise report for map, station locations, calibration, and processing details. The data are taken using an SBE911p system, recording - pressure - temperature (dual system) - conductivity (dual system) - oxygen (dual system) - fluorescence - turbidity.
