Description: |
Variability of dissolved oxygen below the mixed layer is examined in data from Ocean Weather Station P (145°W, 50°N) in the eastern subarctic Pacific. At depths of 150 to 400 m, O2 variability on isopycnals and heaving of the climatological oxycline both contribute importantly to variability on interannual to decadal time scales. O2 anomalies adjusted for isopycnal variations are shown to be well correlated with results from a stochastic climate model driven by local Ekman pumping over the 54 year period, 1956-2010.
