This netcdf file contains the post-processed vessel mounted acoustic Doppler current profiler (VM-ADCP) related to the paper “Atlantic Water pathways around Svalbard mapped using vessel-mounted current profilers” submitted to the Journal of Geophysical Research Oceans. The data from 10 surveys spans the summer month of 2014 – 2017 and is sorted into a structure array along depth and time. The VM-ADCP data were processed with the CODAS processing software package (Hummon, 2016), using 5 min temporal bins and 5 m depth bins. Misalignment of current vectors was removed and acoustic interference with sea floor, CTD cable, nets, and due to ringing were semi-automatically removed from the dataset using the VM-ADCP editing program gautoedit. To ensure consistency between the surveys, all VM-ADCP profiles were binned vertically in 10 m bins between 10 and 700 m (the first bin centered around 15 m). Missing or rejected values are flagged with NaN. Matlab serial date number with the reference date at 00:00 the 01.01.0000. U and V denote the northward and westward current component. The current data marked as “detided” were de-tided by subtracting the AOTIM-5 modelled tidal current from the post-processed VM-ADCP measurements. Along and Across slope components were calculated by rotating each vector according to the local slope aspect as given by the IBCAO bathymetry dataset.
