Editing Ocean heat uptake rate (regional) (section)

== Boundary Conditions ==
Boundary inclusions encompass all ocean waters within the defined regional geographic limits, including surface and subsurface layers where heat exchange and storage occur. The signal includes heat absorbed by mode waters and intermediate waters that contribute to regional heat accumulation.

Boundary exclusions comprise terrestrial environments, atmospheric heat content, and ocean regions outside the specified regional boundaries. Heat fluxes associated with sea ice melting or formation are excluded unless explicitly within the ocean heat content calculation framework. The signal does not include heat stored below the monitored depth range or in sediments.
