Editing Ocean heat content (0–700m) (section)

== Observational Status ==
Continuous monitoring of ocean heat content (0–700m) has improved substantially since the deployment of the Argo program in the early 2000s, providing near-global coverage and high-quality temperature profiles. Historical data from earlier decades are less comprehensive but have been reanalyzed to extend the observational record. Current datasets support ongoing assessments of ocean warming trends and contribute to climate model validation. Future SIGNAL releases may incorporate enhanced spatial resolution, deeper ocean layers, and integration with biogeochemical parameters to provide a more comprehensive view of ocean state changes.
