The rates at which concentrations of oxygen and carbon dioxide in Stuart Channel changed due to biological production and to exchange with the atmosphere were determined from measurements of the simultaneous changes in oxygen, pH, and titration alkalinity over a 15‐day period in July 1976. Carbon dioxide was consumed by plankton at a rate of 10.8 µ mol CO 2 ·liter −1 ·d −1 .CO 2 entered the surface layer by atmospheric exchange at a rate of 0.49 µ mol CO 2 ·liter −1 ·d −1 . The piston velocity was calculated to be 2.2 × 10 −3 cm·s 1 . Oxygen was produced at a rate of 14.1 µ mol O 2 ·liter 1 ·d −1 , due to photosynthetic activity. The rate of oxygen loss to the atmosphere was 9.8 µ mol O 2 ·liter −1 ·d −1 . The piston velocity was 1.6 × 10 −3 cm·s −1 .
