Examples of Sea Regions “North Sea” (i.e. any common-usage named sea or ocean) oA water body with an identified boundaries based on land and/or common circulation patterns around the sea • “Sediment Cell” A water body where the net sediment budget is (close to) zero, typically used for coastal erosion management. • “Circulation Cell” A water body which is the fate for all pollutants entering the water body, typically used for coastal water quality management for example in the Water Framework Directive • “Seabed Area” o Any area of sea characterised by common seabed coverage or depth (e.g. Dogger Bank). • “Exclusive EconomicZone” (UNCLOS) An administrative area recognised by the United Nations, based on the offshore extent from a low tidal boundary

Examples of Ocean Features An Oceanographic Geographic Feature (“Ocean Feature” or “OF”) describes the physical and chemical phenomena of a sea region (known as 'SeaArea' in the Inspire Sea Regions model). Some examples of Ocean Features are: Time series of measurements of water level from a tide guage A gridded field of ocean colour A one off sea surface temperature measurement made by hand with a themometer An ocean climate model predicting future changes of salinity over time on a model grid. In each of these cases some estimation of the value of a property (water level, ocean colour, temperature, salinity) is made using some procedure. For the OF theme we directly build upon the ISO 19156 Observations & Measurements specification which already describes these relationships between the observation (or simulation) event, the observed property, the procedure used and the feature of interest.
