Marine heatwaves are defined as prolonged periods of abnormally high sea surface temperature relative to historical averages.
Between 2015 and 2016, an intense marine heatwave affected large portions of the northeast Pacific. Elevated sea surface temperatures altered plankton communities and reduced krill density in some feeding areas. Blue whales that typically forage off California exhibited distribution changes during this period. NOAA research linked abnormal ocean conditions to broader ecosystem impacts. Reduced prey concentration forced whales to adjust foraging behavior and location. The event illustrated sensitivity of feeding patterns to short-term climate anomalies. Satellite data and field surveys documented biological response to thermal extremes. Heatwaves translate directly into food web variability. Temperature anomalies reshaped migration timing.

Marine heatwaves are projected to increase in frequency under climate change scenarios. Fisheries managers and conservation agencies monitor such events to anticipate ecological disruption. Shifts in whale distribution can increase overlap with shipping lanes or fishing gear. Adaptive management requires real-time environmental data integration. The 2015–2016 event became a case study in climate-driven habitat variability. Policymakers consider resilience strategies for future anomalies. Ocean warming converts climate statistics into ecological movement.
For coastal communities accustomed to predictable whale seasons, altered distribution created uncertainty. Whale-watching operations reported variable sightings linked to ocean conditions. The irony is climatic: a few degrees of temperature change can influence the movements of the largest animal alive. Blue whales respond to prey density, not calendar tradition. Environmental instability complicates conservation planning. Heatwaves ripple upward through trophic levels. Giants follow gradients.
