Theme Sea Regions


Defined Application schemas for Sea Regions theme:

Physical conditions of seas and saline water bodies divided into regions and sub regions with common characteristics 2007 2 EC

A historical version of the theme definition is found in the INSPIRE IMS paper
Seas and saline water bodies divided into regions and sub regions Each region with common characteristics concerning water flow circulation adjacent river catchments bio chemical or temperature of water based on scientific criteria Detailed information at regional level exist INSPIRE IMS 2003

Both Oceanographic geographical features and Sea regions are concerned with physical conditions of marine water masses This is a similar overlap to that which exists for themes 7 13 Atmospheric Conditions and 7 14 Meteorological geographical features To resolve the ambiguity we consider the multi level approach to data needs assessment applied in ETC Data at local or regional level are often needed for management and policy implementation while lower resolution smaller scale data are often required for reporting and policy development evaluation The latter includes summaries and integrated data products

We regard the Sea regions theme as focussing on the local regional level coastal zone

Whereas 7 15 Oceanographic geographical features focuses on physical conditions and general circulation of offshore oceanic waters the Sea regions theme is concerned with marine features of the coastal zone regions defined as transitional waters and coastal waters in the Water Framework Directive
transitional waters bodies of surface water in the vicinity of river mouths which are partly saline in character as a result of their proximity to coastal waters but which are substantially influenced by freshwater flows
coastal waters surface water on the landward side of a line every point of which is at a distance of one nautical mile on the seaward side from the nearest point of the baseline from which the breadth of territorial waters is measured extending where appropriate up to the outer limit of transitional waters

The World Meteorological Organisation also has a geometry based sea region classification dividing the ocean into Marsden Squares
Both biotic and physical parameters and indicators are important in the classification and delineation of sea regions Physical data requirements for important indicators defined in the WFD and the Integrated Coastal Zone Management policy are outlined in the ETC paper These include
nutrients nitrate phosphate and nitrogen phosphorus ratio by regional sea and water body type
concentrations of hazardous substances and pollutants incl heavy metals persistent organic pollutants
productivity indicators incl surface cholorophyll a
biological classification of waters
water masses layers characterised by bulk temperature and salinity properties
polar area features incl pack ice
wind climatological and meteorolog
benthic parameters sediment benthic communities habitats
sea level
chemical species and concentrations
physical characteristics incl temperature salinity
currents including surface currents
tidal zones
