Benson and Krause Equations for the Solubility of Oxygen in Water

For comparison I have given control of 3 lines that follow the Benson and Krause equations outlined in the reference below. Oxygen solubility is displayed in mg/L, salinity is controlled in parts per thousand (ppt), atmospheric pressure is controlled in atmospheres, and temperature is in C.
