### Data description
    Occurrence probability of Seals in the wider Weddell Sea region. Values 0-1
    
### Processing steps:

    1.  Download Seal_abundance_Modelled_prediction_values.shp from https://doi.org/10.1594/PANGAEA.899619
	
    2.  Reproject to EPSG:3031
        ogr2ogr -t_srs EPSG:3031 Seal_occurrence_probability_3031.shp Seal_abundance_Modelled_prediction_values.shp
    
    3.  Rasterize (burn-in value = 'lg_10_sc'), set explicit NoData and suitable gridsize, convert to Cloud-Optimised Geotiff (COG)
