The data specifications of Sea regions are described in the following tables: Coastline Feature Type Constraint OCL Natural language coastline is special case of shoreline at Mean High Coastline is a special case of shoreline at Mean High Water Level. Coastline is the Level boundary between land and sea to be used for viewing, discovery and general purpose applications where a land/marine boundary is required. Where there is not significant variation in water level, MSL can be used as a substitute for MHW. InterTidalArea Feature Type Attribute Description Value type Multiplicity voidable highWaterLevel The high water level which was used to define the upper limit of the Intertidal WaterLevelValue 1 Area, e.g. 'meanHighWater'. owWaterLevel The low water level which was used to define the lower limit of the Intertidal WaterLevelValue 1 Area, e.g. 'meanLowWater'. MarineCirculationZone Feature Type Attribute Description Value type Multiplicity zoneType The type of the Marine Circulation Zone, e.g. sedimentCell. ZoneTypeValue 1 extent The extent of the Marine Circulation Zone at a particular tidal state Extent of MarineExtent 1 the Marine Circulation Zone.
