    Teschke, Katharina; Pehlke, Hendrik; Brey, Thomas (2019): Spatial distribution of zooplankton (Antarctic krill, ice krill) in the wider Weddell Sea (Antarctica) with links to ArcGIS map packages [dataset]. PANGAEA, https://doi.org/10.1594/PANGAEA.899667

### Processing steps:

    1.  Download Data_shapefile_raster_zooplankton.zip from https://doi.org/10.1594/PANGAEA.899667, unzip and file in cwd/input

    2.  Run 02_process_krilldata.py
        * Read krill datasets from input/
        * Process larval Antarctic krill:
            - Reproject vector data to EPSG:3031
            - Rasterize abundance attribute at 1 km resolution
            - Set NoData to -3.4e38
        * Process adult Antarctic krill:
            - Calculate maximum valid habitat suitability value and rescale to 0-1
            - Set cells with a value of 0 to NoData
            - Reproject to EPSG:3031 (bilinear resampling)
        * Process ice krill:
            - Convert density from log10(individuals/m³) to individuals/m³
            - Reproject to EPSG:3031 (bilinear resampling)
        * Save all outputs as DEFLATE-compressed Cloud Optimised GeoTIFFs in output/
