A minimum set of key ocean variables, agreed internationally, that are critical to understanding and track ocean change, guiding policy, and can be observed feasibly and cost-effectively across platforms.
Data that are Findable, Accessible, Interoperable, Reusable.
Indicators are scientifically validated metrics translating complex ocean changes (e.g., biogeochemical ones) into measurable, policy-relevant information.
Measurements taken directly in the ocean (e.g., floats, ships, moorings).
Marine Spatial Planning
Integrated network of platforms, sensors, and data streams used to monitor ocean conditions.
A phenomenon in the ocean-indicator context is a distinct and meaningful process, state, or change in the ocean system (physical / biogeochemical / ecosystem) that is observable (or measurable) and for which indicators can be developed to monitor its status, trend or variability.
Ocean observations made via satellites or airborne sensors.
How often measurements are taken.
Geographic extent of observations.
Ability to detect short- vs long-term changes.
Quantified confidence or error associated with measurements or indicators.
