Editing Ocean heat content (section)

== Boundary Conditions ==
Boundary inclusions for ocean heat content encompass the entire water column of the global ocean, typically from the surface down to depths of 2000 meters or more, where data availability permits. It includes all ocean basins and coastal regions where measurements are feasible. Boundary exclusions involve areas where ocean water is absent, such as land masses and inland water bodies, and regions with insufficient observational coverage or data quality. The signal excludes heat content changes attributable to non-thermal factors such as salinity variations or chemical composition changes unless they indirectly affect temperature.
