AREX 2017 selected hydrographic profiles: CTD and oxygen concentration in the south-west Spitsbergen area

Data from AREX 2017 cruise aboard rv Oceania collected in July 2017 on the south-western Svalbard shelf in the MathWorks Matlab table and Microsoft Excel formats.

This data selection was used and described in Vivier et al., 2024: Dense water production in Storfjorden, Svalbard, from a one-year time series of observations and a simple 3 model: Are polynyas in a warming Arctic exporting heat to the deep ocean? (for publication in JGR Oceans).

The sampling took place during the Arctic Experiments AREX carried out by the Institute of Oceanology, Polish Academy of Sciences (IO PAN), Sopot, Poland since 1987 until present.

During the AREX 2017 cruise CTD (conductivity, temperature, depth) vertical profiles were taken from surface to bottom with Sea-Bird Electronics, Inc. SBE 911plus CTD system (composed of duplicate SBE 3plus Temperature sensors, SBE 4C Conductivity sensors, and a Digiquartz® Pressure sensor, all calibrated by the manufacturer before each cruise). In addition to standard sensors, the system was equipped with the SBE43 dissolved oxygen sensor. Raw data were then filtered and processed with the SBE Data Processing Software (averaged to 1 dbar intervals) and further analysed and visualised in the MATLAB and exported to Excel (variables were rounded, blank values kept). Raw data are available from the IO PAN, Sopot, Poland (https://www.iopan.pl/).
