Estimate oxygen saturation concentration

Usage

o2_at_sat(
  temp,
  depth,
  baro,
  altitude = 0,
  salinity = rep(0, length(temp)),
  model = "garcia_benson"
)

Arguments

temp: water temperature (°C)
baro: barometric pressure (mb)
altitude: altitude (m). Only used if `baro` is missing.
salinity: salinity (ppt).
model: character, solubility model to use. Options are "garcia", "garcia_benson", "weiss", or "benson".

Value

numeric vector of oxygen saturation concentrations (mg/L)
