| Summary: | The data is divided three: SpatialData.rda : The Rdata file contains indices of density of several marine fish species across the Barents Sea, which were derived from data collected by the Norwegian Institute for Marine Research and the Polar Research Institute of Marine Fisheries and Oceanography from January to March, every year from 1985 to 2016. The data is structured as following: "Data" is divided into each of the species .In order: North East Atlantic (NEA) cod ( Gadus morhua) , NEA haddock ( Melanogramus aeglefinus) , NEA saithe ( Pollachius virens) , beaked redfish ( Sebastes mentella) , golden redfish ( Sebastes marinus) , blue whiting ( Micromesistius poutassou) , Barents Sea capelin ( Mallotus villosus) and Norwegian spring-spawning herring ( Clupea harengus ). "Data[[<>]]" is further divided into the ten resolution the density indices were grouped by. The resolution (i.e. size in km2 of each of the hexagonal cell of the grid used to spatially divide the Barents Sea), are given by the name of the sublist, namely 2500, 4900, 9100, 12100, 16900, 22500, 28900, 36100, 44100, 52900. Data[[<>]][[<>]] is divided into:"dmatrix" --> a matrix with the densities of the given species of each cell and year."LLmat" --> a matrix with coordinates of the centres of each of the cells.

The methodology used to calculate these variables can be found in Bjørkvoll et al. 2012 ______________________________________________ Scaling_LifeHist.N.boot.r & Scaling_LifeHist.r.boot.r : R scripts used to test the relationship between life history and spatial synchrony |
