Fig. 2: Exposure of 43 economic units to historical marine heatwaves between 1982 and 2021.
From: Past and future impacts of marine heatwaves on small-scale fisheries in Baja California, Mexico
Panel a shows a discrete Hovmöler diagram with time along the x-axis (years) and anonimized unique economic unit identifiers along the y-axis [latitudinally organized, north (top) to south (bottom)]. The color scale indicates the annual cumulative marine heatwave intensity (°C days) experienced by each economic unit; a value of cumulative marine heatwave intensity of 0 indicates no marine heatwave for that year and TURF. For economic units with more than one TURF, we show the area-weighted mean. Panel b shows boxplots for annual cumulative marine heatwave intensity during each El Niño event (points inside boxplots show the mean cumulative intensity), and years not categorized as El Niño events. Panels c–f show boxplots for the number of marine heatwaves per year, days under marine heatwave per year, mean marine heatwave intensity per year and cumulative intensity (°C days) per year, before (1982–2013) and during (2014–2016) the marine heatwave regime.
