The dataset consists of 112 connectivity matrices produced by the oceanographic model Arctic4, and 14 connectivity matrices produced by the oceanographic model TOPAZ. The connectivity matrices are found in two .zip archives: ‘PAME Arctic4 CM.zip’ and ‘PAME TOPAZ CM.zip’. The Arctic4 matrices are means for the period 2007 to 2016, and the TOPAZ matrices for the period 1991 to 2015. Both sets are divided into one set for the warm season (March to October) and one set for the cold season (November to February). The Arctic4 matrices cover dispersal at the depths: 0, 10, 15, 30, 50, 70, 100, and 150 m, and for the Pelagic Larval Duration (PLD) of: 5, 10, 15, 30, 45, 60 and 90 days. The TOPAZ matrices are only available for the surface (0 m) and for the PLDs: 5, 10, 15, 30, 45, 60 and 90 days. Complete lists of all connectivity matrices are found in the file ‘Matrix file list.xlsx’.

The connectivity matrices describe the dispersal probability (0 to 1) between all 40893 model grid cells within the selected Arctic Ocean domain (depth ≤500 m). The elements in the connectivity matrix are read as the probability of dispersal from the grid cell specified by the column number to the grid cell specified by the row number, i.e. “from column to row”. The geographic coordinates of row and column numbers are found in the file ‘Matrix file list.xlsx’, given as longitude and latitude in decimal degrees (grid cell centers).

All matrices are stored as Matlab binary files (.mat).
