carbulate: Calculate Carbonate Speciation using DIC, pH, and Temperature

In paukes/carbulate: carbulate: Calculate Carbonate Speciation using DIC, pH, and Temperature

Description

This function calculates the speciation of dissolved inorganic carbon given the measured pH, DIC concentration, and water temperature. It will add on the concentrations of each carbonate species (CO2(aq), HCO3-, CO3–) to your dataframe 'dat'.

Usage

carbulate(dat, DIC_col_mg.L, pH_col, temp_col_C, pressure_col_kPa)

Arguments

dat	Your dataframe with parameters of interest
DIC_col_mg.L	Name of column that contains your measured dissolved inorganic carbon concentration (mgC/L)
pH_col	Name of column with your measured pH
temp_col_C	Name of column with your measured water temperature (in Celsius)
pressure_col_kPa	Name of column with the field atmospheric pressure (in kPa)

Examples

water.dat <- data.frame(sample = c('Lake A', 'Lake B', 'Lake C'),
Baro_kPa = c(99.9,98.8,98.9),
DIC_mgC.L = c(1.2,8.5,15),
pH = c(6.8, 7.2, 5.5),
Temp_C = c(12,15,18))

water.dat <- carbulate(water.dat, 'DIC_mgC.L', 'pH', 'Temp_C', 'Baro_kPa')
