Year in Review

At the Cape Elizabeth OCNMS mooring in 42 m of water (~47 N), the forecasts predicted the onset of hypoxic conditions (<2 mg oxygen / L) very closely to what was observed. The April forecast predicted a brief period of hypoxia from May 24-30 and returning to hypoxic conditions again on June 27, while the January forecast predicted hypoxia beginning on June 23. This location observed hypoxia beginning on June 22. The forecast predicted the location would remain hypoxic and develop anoxia in late July through mid-October. The observations show that while this location remained hypoxic but likely never went anoxic.
