Ocean indicators are necessary because they translate complex ocean data into simple, practical measures of the ocean’s state and climate, which, when combined with science-based knowledge, can inform policymakers and other stakeholders and ultimately support decision-making for a sustainable future, benefiting both society and the economy.

One of the challenges in ObsSea4Clim is to define the proposed ocean indicators for the Essential Ocean Variables (EOVs) such as sea surface temperature (SST), subsurface temperature, sea surface height, and sea ice and to regionalise the indicators. Regionalised ocean indicators help understand which regions exhibit unique oceanic and climatic patterns, the factors driving these patterns, and how they relate to global trends.

This report presents our proposed ocean indicators, the approach to their regionalization, as well as extreme ocean indicators.
