Future hypoxia in British Columbia

Hypoxia, a state of low oxygen concentration, is present in some British Columbia (BC) sub-surface waters. Two regions, the Gulf of Alaska and the US continental slope from California to northern BC, are sources of hypoxic water, but their relative contributions to this situation are unknown. This project will provide graphs of oxygen concentration and use historical data to assess the relative contributions of the two regions to predict future oxygen concentration trends in BC.
