ctdfjorder.CTD.CTD.add_dynamic_height(self, p_ref: float | ndarray = 0) → None

Calculates and adds dynamic height anomaly to the CTD data using the TEOS-10 formula.

This method computes the dynamic height anomaly, which represents the geostrophic streamfunction that indicates the difference in horizontal velocity between the pressure at the measurement point (p) and a reference pressure (p_ref).

Raises:

NoSamplesError – When the function is called on a CTD object with no data.

Parameters:

p_ref (Union[float, np.ndarray], optional) – Reference pressure, in dbar. The default is 0 dbar, corresponding to the sea surface.

Notes

The gsw.geo_strf_dyn_height function from the Gibbs SeaWater (GSW) Oceanographic Toolbox is utilized for this calculation. More information about this function can be found at the TEOS-10 website.

Examples

ctd_data = CTD('example.csv')
ctd_data.add_dynamic_height()
# This will add a new column with dynamic height values to the dataset, calculated using the TEOS-10 formula.
