R/schoolRelativeDimension.R
schoolRelativeDimension.Rd
This function calculates the relative school dimension of Diner (2001)
schoolRelativeDimension(Sv, L, P, Th, theta)
Sv | Observed mean volume backscattering strength (Sv) of a school |
---|---|
L | Observed (uncorrected) school length, m |
P | Mean depth of school |
Th | Minimum Sv data threshold used to detect schools using the SHAPES algorithm |
theta | Transducer 3 dB beam width, degrees |
