Sea level riseRelated: It tracks the heat uptake that drives much of seawater’s expansion.
Marine heatwaveRelated: Changes in stored heat can sustain unusually warm surface conditions.
StratificationRelated: Stratification affects how heat is distributed and stored below the surface.
ArgoRelated: Argo observations reveal how much heat the upper ocean absorbs and stores.
