Extreme mortality and reproductive failure of common murres resulting from the northeast Pacific marine heatwave of 2014-2016
Fig 1
Average monthly time series (Jan 1870 to Dec 2018) of sea surface temperature anomalies (SSTa) in the (a) Gulf of Alaska (GOA); and in (c) northern (nCCS); (e) central (cCCS); and (g) southern (sCCS) waters of the California Current System (CCS). Solid black lines are 24-month running averages. Also presented are 5-year running averages of annual SST differences, an index of SST change rate, for the (b) GOA, and (d) nCCS, (f) cCCS and (h) sCCS. Average long-term SST values for each region are: GOA 8.1° C, nCCS 12.5° C, cCCS 13.9° C, sCCS 16.2° C.
