Abstract:
Ocean data from two ocean moorings, M1 and M2. Both were Nansen Legacy gateway moorings deployed in the northern Barents Sea at potential “gateways” of ocean exchange with the north and east. The moorings were equipped with ADCPs measuring ocean currents, and temperature and conductivity-temperature-pressure sensors at various points along the mooring line:
- Conductivity, temperature, and pressure from RBR Concerto and SBE16plus v2 instruments.
- Temperature from RBR Solo instruments.
- Near-surface ocean currents from upward-looking Nortek Signature 500 kHz ADCP instruments.
- Water column currents from upward-looking RDI 150 kHz ADCP instruments.
The current version of the dataset (V1) contains data from three deployments of M1 and M2, covering the period from October 2018 to November 2021. At the M1 mooring, there is a gap between the end of the second deployment (21.09.2020) and the start of the third one (20.02.2021).
The document M1_M2_data_processing_details_2018_2020.pdf contains details about the data and processing, as well as important information for users of the data. The follow-up document mooring_processing_m1_m2_2020_2021.pdf contains additional data from the third deployment

Version history
V1 (27-07-2022): Created dataset, uploaded raw and processed data for M1 and M2 (2018-2020) with documentation.
- 24-05-2024: Added processed CTD data from M1-3 (2021 deployment).
- 07-06-2024: Added processed CTD data from M2-3 (2020-2021 deployment).
Files
Processed data are organized per mooring and deployment. E.g., m1_2.zip contain processed data from deployment 2 (2019-2020) of the M1 mooring, etc. All raw data are collected in raw_m1m2_2018_2020.zip and raw_m1m2_2020_2021.zip.
For the third deployment (2020-2021), there are separate files for CTD and current data from each mooring.
Quality
Data are available both in raw form and as netCDF files with processed data.
The document M1_M2_data_processing_details_2018_2020.pdf and the follow up mooring_processing_m1_m2_2020_2021.pdf contain further details about the data and processing, as well as important information for users. This includes important caveats about a.a. sensor position in the water column, current headings, and ad hoc drift corrections applied to salinity data.
