rLakeAnalyzer (version 1.11.4.1)

center.buoyancy: Calculates the center of buoyancy.

Description

Calculate the center of buoyancy using buoyancy frequency with a center of mass analysis. Brunt-Vaisala frequency is used for a temperature profile. Negative values for N2 are set to 0 (as they represent transient instabilities or sensor calibration issues) for this calculation.

Usage

center.buoyancy(wtr, depths)

Arguments

wtr

a numeric vector of water temperature in degrees C

depths

a numeric vector corresponding to the depths (in m) of the wtr measurements

Value

Returns a value for the center of buoyancy.
