Editing Sea ice area extent (regional) (section)

== Aggregation Semantics ==
Geographic aggregation involves summing sea ice area within predefined regional units, such as the Arctic Ocean basin or the Antarctic coastal zones, to provide regional extent values. Temporal aggregation is frequent, often daily or weekly, to capture dynamic changes in ice coverage. Cross-signal aggregation may involve integrating sea ice extent data with related environmental signals such as [https://en.wikipedia.org/wiki/Sea_surface_temperature sea surface temperature] or atmospheric temperature to analyze coupled system interactions. Aggregation methods account for spatial heterogeneity and temporal variability to support comprehensive environmental assessments.
