Climate model projections also reveal that, under 2°C of global warming, 98% of the ocean volume down to 2000 meters is expected to experience some form of extreme event every single day.

(But only when extremes are defined relative to a fixed preindustrial baseline.)

We find that subsurface compound events are closely tied to vertical shifts in water masses.

We assess their present-day distribution using climate model outputs, which we compare to recent observation-based data

🌊🔥 Marine heatwaves often do not occur in isolation—they frequently coincide with extreme conditions in ocean acidity and oxygen levels.

In our new paper, we assess the distribution and projected changes of these compound ocean extremes within the top 2000 meters of the ocean.
Surface and Subsurface Compound Marine Heatwave and Biogeochemical Extremes Under Climate Change
Extreme conditions in temperature, acidity and oxygen frequently coincide at the sea surface and in large parts of the subsurface ocean Subsurface compound events are often linked to vertical wat...
