| Summary: | These data were created to analyse the Atlantic Water (AW) temperature maximum (i.e. the AW core) across the Arctic from many observational programs between 1977 - 2018, with the aim to give a picture of the spatial and temporal variation in the AW core. The AW core temperature, salinity and pressure (depth) are included. The data are in netCDF format, and can be interpreted by a range of software e.g. Python (xarray module), Matlab, cdo, nco, etc. The AW core of a given vertical profile is defined here as the warmest part of the profile with salinity greater than 34.7 psu. To promote accurate AW core identification, only profiles that started above 100 m depth and sampled more than 500 m of the water column are included in this dataset. Furthermore, before locating the AW core, profiles were smoothed over a vertical distance of 80 m by taking the mean of the profile data within 40 m of each data point. This removed spikes due to thermohaline intrusions and eddies, whilst preserving the general shape and magnitude of the temperature profile. Please note that in the original paper which used this data (Richards et al. 2022), monthly mean profiles were used for mooring data, whereas this dataset includes all mooring profiles. This gives the user maximum flexibility. |
