“…Along the eastern Pacific of North America, warm-temperate and subtropical species move poleward during short-term warm water anomalies, such as an El Niño Southern Oscillation (ENSO) event (Lonhart and Tupen 2001;Lonhart 2009). Counter-currents develop and flow poleward for several months during an ENSO event, dispersing low-latitude larvae and adults beyond their normal geographic range (Zacherl et al 2003;Cavole et al 2016;Feeney and Lea 2016;Goddard et al 2016). Like ENSO events, particularly long MHWs can increase poleward flow of coastal currents and sustain abnormally high temperatures, both of which contribute to movement of coastal marine species from low to high latitudes (Sanford et al 2019).…”

Background: Ongoing global ocean warming and a recent increase in the frequency and duration of marine heatwaves have demonstrably impacted marine ecosystems. Growing evidence points to both short-and longterm biological changes, across several levels of organization. While range shifts are among the predicted responses, few studies are focused solely on documenting such changes. Here we report ecological changes in response to marine heatwaves across multiple taxa in the eastern Pacific from central California to Baja California. Methods: Sea surface temperature data from two estuaries and one coastal site were analyzed to define the number, duration, and intensity of marine heatwaves occurring in central and southern California from 2013 to 2018. Long-term monitoring programs and short-term research projects in coastal and estuarine ecosystems serendipitously collected specimens or photographs of extralimital species from central California to the Baja California Peninsula. Spatial and temporal sampling protocols and the targeted species for six unrelated programs varied greatly, from annual to monthly at both fixed and variable locations. In addition, anomalous occurrences were reported to staff at local and regional marine and estuarine protected areas and noted in local news and social media outlets. Anomalous range detections were categorized as range expansions and extensions, reappearances, abundance increases, shifts into new habitats, and range contractions. Results: Multiple marine heatwaves occurred from 2014 to 2018, peaking in 2015. Marine heatwaves were more intense and longer in the estuaries, with a maximum duration of 109 days in 2015. We observed 29 species that had responded to the warm water anomalies of 2014-2018 along the eastern Pacific Ocean between central California and the Baja California Peninsula: 7 expansions, 2 extensions, 10 reappearances, 7 increases, 2 shifts into new habitats, and 1 apparent contraction. These shifts included algae, invertebrates and fishes. Twenty species were observed by professional biologists involved both in long-term monitoring programs and short-term studies, 6 by amateur naturalists as part of community-based science programs in the field, and 3 through a combination of all three.

“…In 2015 that dramatically increased to five strandings. Califor¬ nia experienced a strong El Nino event starting in 2015, lasting into 2016, with warm wa¬ ter, and the appearance of tropical fishes such as Blue Marlin, Wahoo, Yellowtail Jack and Bigeye Scad (Feeney and Lea 2016;Love et al 2015). No California sightings of oarfish occurred in 2016 or as yet in 2017.…”

“…These included dorado ( Coryphaena hippurus ), wahoo ( Acanthocybium solandri ), blue marlin (Makaira nigricans ), and hammerhead sharks ( Sphyrna spp) (Cavole et al., ). Other species, such as Pacific bluefin tuna ( Thunnus orientalis : PBF), were seen in unusually large numbers, and earlier in the year than is typical (Feeney & Lea, ; Leising et al., ). These unusual biological occurrences appear to be associated with the “Blob” marine heatwave (Bond, Cronin, Freeland, & Mantua, ; Zaba & Rudnick, ), and subsequent 2015–2016 El Niño.…”

We investigate the impact of oceanographic variability on Pacific bluefin tuna (Thunnus orientalis: PBF) distributions in the California Current system using remotely sensed environmental data, and fishery‐dependent data from multiple fisheries in a habitat‐modeling framework. We examined the effects of local oceanic conditions (sea surface temperature, surface chlorophyll, sea surface height, eddy kinetic energy), as well as large‐scale oceanographic phenomena, such as El Niño, on PBF availability to commercial and recreational fishing fleets. Results from generalized additive models showed that warmer temperatures of around 17–21°C with low surface chlorophyll concentrations (<0.5 mg/m3) increased probability of occurrence of PBF in the Commercial Passenger Fishing Vessel and purse seine fisheries. These associations were particularly evident during a recent marine heatwave (the “Blob”). In contrast, PBF were most likely to be encountered on drift gillnet gear in somewhat cooler waters (13–18°C), with moderate chlorophyll concentrations (0.5–1.0 mg/m3). This discrepancy was likely a result of differing spatiotemporal distribution of fishing effort among fleets, as well as the different vertical depths fished by each gear, demonstrating the importance of understanding selectivity when building correlative habitat models. In the future, monitoring and understanding environmentally driven changes in the availability of PBF to commercial and recreational fisheries can contribute to the implementation of ecosystem approaches to fishery management.
