abundance

echopype.metrics.abundance(ds: Dataset, range_label='echo_range') → DataArray

Calculates the area-backscattering strength (Sa) [unit: dB re 1 m^2 m^-2].

This quantity is the integral of volumetric backscatter over range (echo_range).

Parameters

dsxr.Dataset

range_labelstr

Name of an xarray DataArray in ds containing echo_range information.

Returns

xr.DataArray
