At the Ćháʔba buoy (~48°N in 90 m of water), on the northern end of the Washington shelf, the forecast predicted that the location would not develop hypoxia over the 2013 upwelling season. Except for two short events (about five-six days each) the location did not go hypoxic. At the Cape Elizabeth OCNMS mooring in 42 m of water (~47°N), the forecast predicted the onset of hypoxic conditions (<2 mg oxygen / L) on 27th of June (April forecast), the 4th of July (Feb forecast) or August 1st (March forecast). This location observed hypoxia on 11th of July. The forecast predicted the location would remain hypoxic and develop anoxia in September. The observations show that while this location remained hypoxic until the 5th of September, the location never went anoxic.
