Species Threshold File (Optional)

The receptor file serves as an additional input to each module, which can either be in .csv or .tif format.

Receptor File

Contains values indicating thresholds, grid scaling, and variable selections.

  • File Type: Supports only .csv file format.

    • Species: Optional; can be used for output.

    • ParAcousti Variable: Variables and weightings may vary depending on species.

    • Threshold (db re 1 uPa): Threshold above which negative impacts are expected. Units should match Paracousti Variable.

    • Depth Averaging (Default: DepthMax):

      • DepthMax: Use the maximum value for each vertical column.

      • DepthAverage: Use the average value for each vertical column.

      • Top: Use the top/surface bin for each vertical column.

      • Bottom: Use the bottom/bed bin for each vertical column.

    • Species File Averaged Area (km²): Represents cumulative area for each cell regarding species percent and density; used for scaling to each ParAcousti grid cell. Leave blank or set to 0 to prevent scaling.
