Bottom layer characteristics from HIROMB model: •Current velocity, cm/s: maximum, average, standard deviation

•Water salinity, “psu”: minimum, maximum, average, standard deviation

•Water temperature, ºC: minimum, maximum, average, standard deviation – for December-April and June-October periods

Nodes of HIROMB model, data from which have been used for analysis of bottom layer temperature, salinity and currents in the Polish EEZ. Data of the period 18.12.2001 – 26.04.2008
