| Summary: | Progress Code: completed Statement: Cell resolution was set up at 0.1 degree with R 3.3.0 software. These data needed to be corrected for precise depth accuracy. It was performed using ArcGIS and following the protocol proposed by Guillaumot et al. 2016. A seafloor temperature layer was generated based on available modelled temperatures for multiple depth layers of the water column. Due to missing data, some values were interpolated using the nearest neighbour method with Arctoolbox. Purpose This dataset can be used for biogeographic and macroecology studies at the Southern Ocean scale and constitutes a useful tool for species distribution modelling. These environmental parameters are relevant for echinoid ecology. Environmental descriptors that are available for the study area (-180 degrees W/+180 degrees E; -45 degrees/-78 degrees S) and for the following periods: 1955-1964, 1965-1974, 1975-1984, 1985-1994, 1995-2012. They were compiled from different sources and transformed to the same grid resolution of 0.1 degree pixel. We also provide future projections for environmental descriptors established based on the Bio-Orable database (Tyberghein et al. 2012). They come from IPCC scenarii (B1, AIB, A2) for years 2100 and 2200 (IPCC, 4th report).
