RSKderivebuoyancy.m

Arguments

Input

 -Required- 

  • RSK - Structure containing the logger metadata and data

 -Optional-

  • latitude: latitude in decimal degrees north. If latitude is not provided, a default gravitational acceleration 9.7963 m/s^2 will be used.
  • seawaterLibrary: specify which library to use, should be either 'TEOS-10' or 'seawater', default is TEOS-10.

Output

  • RSK - Updated structure containing buoyancy frequency and stability.


This function derives buoyancy frequency and stability using the TEOS-10 GSW toolbox or seawater library.  The new variables are stored in new columns in the data table.  

Example:

rsk = RSKderivebuoyancy(rsk,'latitude',50)

The Absolute Salinity anomaly is taken to be zero to simplify the calculation.
