Brief description

This dataset contains environmental layers used to model the predicted distribution of demersal fish bioregions for the paper: Hill et al. (2020) Determining Marine Bioregions: A comparison of quantitative approaches, Methods in Ecology and Evolution.
It contains climatological variables from satellite and modelled data that represent sea floor and sea surface conditions likely to affect the distribution of demersal fish including: depth, slope, seafloor temperatures, seafloor current, seafloor nitrate, sea surface temperature, chlorophyll-a standard deviation and sea surface height standard deviation. Layers are presented at 0.1 degree resolution.
"prediction_space" is a Rda file for R that consists of two objects:
env_raster: a raster stack of the environmental layers
pred_sp: a data.frame version of the env_raster where some variables have been transformed for statistical analysis and bioregion prediction.
"Env_data_sources.xlsx" contains a description of each environmental variable and it's source.

Notes

Purpose
This dataset was used as an example dataset in the paper: Hill et al. (2020) Determining Marine Bioregions: A comparison of quantitative approaches, Methods in Ecology and Evolution. Different analytical approaches to determining bioregions were compared using this data and associated demersal fish data contained in: AAS_4142_RSTS_DemersalFish_Extract
