This function averages SumNASCData
horizontally to the acoustic PSU resolution, weighted by the log distance. Optionally, NASCData
can be used as input, in which case SumNASC
is run first.

The NASCData
data.
The SumNASCData
data.
The method to use for defining the Layers, one of FunctionParameter
to define the Layers on the fly in this function, FunctionInput
to import Layer process data generated using the function DefineAcousticLayer
, or PreDefined
whihc requires SumNASCData
as input.
See the argument DefinitionMethod
in DefineBioticLayer
.
Numeric: A single numeric giving the thickness of the layers.
A table of Layer name, MinLayerDepth in meters and MaxLayerDepth in meters, defining the Layers.
The AcousticLayer
process data.
The method to use for defining the Survey, one of FunctionParameter
to define the Survey on the fly in this function, or FunctionInput
to import Survey process data from a previously run process by the input Survey
.
See DefineSurvey
A table of the two columns Stratum and Survey.
The Survey
process data.
The method to use for defining the PSUs, one of FunctionParameter
to define the PSUs on the fly in this function, or FunctionInput
to import PSU process data from a previously run process by AcousticPSU
.
Character: A string naming the automatic PSU definition method to use. Currently only the option "EDSUToPSU" is supported, which sets each EDSU as a PSU. See DefineAcousticPSU
for details.
The StratumPolygon
process data.
The AcousticPSU
process data.
