Calculate the CO2 solubility coefficient — calc

Calculates the Weiss (1974) CO2 solubility coefficient, K0, for water at the supplied temperature, salinity, atmospheric pressure, and water depth. The depth and atmospheric pressure terms apply a pressure correction for the total pressure at the sensor.

Usage

calc_K0(temp_water, waterDepth_m = 0, atmo_press = 1, salinity = 0)

Arguments

temp_water: Numeric vector. Water temperature in degrees Celsius.
waterDepth_m: Numeric vector. Water depth in meters. Defaults to 0.
atmo_press: Numeric vector. Atmospheric pressure in atm. Defaults to standard atmosphere (1).
salinity: Numeric vector. Salinity in practical salinity units. Defaults to freshwater (0).

Value

Numeric vector of K0 values in mol/(kg atm).
