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.

SR Issues to Consider

• Code Lists
• Especially for SeaArea names
• Further specialisation of MarineCirculationZone?
• Attribution of MarineAdiminisatrativeZone

OF Issues to Consider

• Code Lists
• Portrayal of coverages
• Link to EMF
• Scope of phenomena
• Suggest those mandated in legislation not all
• Vocabularies for phenomena
• CF_Names, SeaDataNet
• Binary encodings and linking to GML AS
