At the Cape Elizabeth OCNMS mooring in 42 meters of water (~47°N), the forecasts predicted the onset of hypoxic conditions (<2 mg oxygen / L) very closely to what was observed. The forecasts predicted hypoxia for more than 8 consecutive days beginning on Jun 27 (January and April forecasts); this location observed hypoxia beginning on June 20. The forecast predicted the location would remain hypoxic and develop anoxia in late August through mid-October.
