po2: Pressure of dissolved oxygen in air or water

In denis-chabot/fishMO2: Calculate and Plot SMR, O2crit and SDA, and convert between oxygen units

Description

Calculate oxygen partial pressure as a function of temperature and salinity. Oxygen is a constant fraction (o2frac) of total gas pressure after removing water vapor pressure.

Usage

po2(t, s = 0, p = 101.325)

Arguments

t	A vector of temperature values in degrees Celsius
s	A vector of salinity values (parts per thousand)
p	Total gas pressure (in kPa), typically atmospheric pressure above the body of water

Details

See Warnings.

Value

Partial pressure of oxygen in kPa

Warnings

It is assumed that vectors t and s have the same length, or that one of the two is a constant value. This is not checked in the present version, the user must make sure it is the case.
