ME44E:
Pacific Ocean Anomalies of 2014–2015: Consequences for Marine Ecosystems II Posters


Session ID#: 9540

Session Description:
Unusual atmospheric and ocean conditions existed across much of the North Pacific in 2014 and early 2015, especially in middle to high latitudes.  Sea surface temperature anomalies reached >2.5º C in the central Gulf of Alaska (colloquially referred to as ‘The Blob’); it has been suggested that these conditions are related to an unusually strong and persistent pattern of elevated atmospheric pressure in the region, the ‘Ridiculously Resilient Ridge’.  In parts of the California Current System (CCS), temperature anomalies exceeded 5º C.  It is not clear whether the warming off the west coast of North America is directly related to the high latitude anomalies, or is part of a separate regional warming near the southern end of the CCS.  Numerous biological perturbations have been associated with the NE Pacific ocean/atmosphere anomalies, including depressed Chl-a, geographic shifts of zooplankton and other taxa, reduced biomass of some small pelagic fishes, increased pinniped strandings, altered breeding success and survivorship of some seabirds, etc.  This session invites contributions pertaining to physical oceanographic and atmospheric conditions during 2014-2015, or evidence for biological or biogeochemical responses.  We encourage both observational evidence and models representing the dynamical basis of the anomalous conditions and ecosystem responses.
