# center.buoyancy: Calculates the center of buoyancy. In rLakeAnalyzer: Lake Physics Tools

## 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

 `1` ```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.

`buoyancy.freq`, `ts.buoyancy.freq`, `center.buoyancy`

## Examples

 ```1 2 3 4 5 6 7 8 9``` ``` # 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) ```
