• Sea Regions (INSPIRE, 2007) Physical conditions of seas and saline water bodies divided into regions and sub-regions with common characteristics.
• Ocean Geographic Features (INSPIRE, 2007) Physical conditions of oceans (currents, salinity, wave heights, etc.).
• Need clear strong distinction between SR + OF– Support organisations involved with Inspire compliance
• Inspire specifications needs to be positioned to maximise value to both consumers and producers– Aligned with community practice on how data is generated and managed will help!
– Sea Region is a defined marine area of common physical and/or chemical characteristics.
– A Sea Region will contain Ocean Geographical Features (Annex III) that represents the precise physical or chemical properties of the Sea Region.
– A Sea Region may have other properties that are not an Ocean Geographical Feature, for example bathymetry (Elevation theme - Annex II) and shipping lanes (transport theme – Annex I).
– A Sea Region will be a vector dataset and not be represented as a ‘coverage’ (ISO 19126) where as an Ocean Geographical Feature will.
– An Ocean Geographical Feature is the result of an observation or measurement process, not the process itself (which is described by an Environmental Monitoring Facility - Annex III)
• “North Sea” (i.e. any common-usage named sea or ocean) A 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” 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
• 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.
