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.

Examples

# A vector of water temperatures
	wtr = c(22.51, 22.42, 22.4, 22.4, 22.4, 22.36, 22.3, 22.21, 22.11, 21.23, 16.42, 
		15.15, 14.24, 13.35, 10.94, 10.43, 10.36, 9.94, 9.45, 9.1, 8.91, 8.58, 8.43)

	#A vector defining the depths
	depths = c(0, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 
		17, 18, 19, 20)
	
	c.b = center.buoyancy(wtr, depths)
