• Description:
  Climate change has exacerbated the occurrence of large-scale sea surface temperature anomalies, or marine heatwaves (MHWs) —extreme phenomena often associated with mass mortality events of marine organisms. Using a combination of citizen science and federal data sets, we investigated thecausal mechanisms of the 2014/2015 die-off of Cassin ’s Auklets ( Ptychoramphus aleuticus ), a small zooplanktivorous seabird, during the NE Paci fic MHW of 2013 –2015. Carcass deposition followed an effective reduction in the energy content of mesozooplankton, coincident with the loss of cold-water foraging habitatcaused by the intrusion of the NE Paci fic MHW into the nearshore environment. Models examining interannual variability in effort-controlled carcass abundance (2001 –2014) identi fied the biomass of lipid-poor zooplankton as the dominant predictor of increased carcass abundance. In 2014, Cassin ’s Auklets
