2. Introduction Objectives and how we got here
Common Understanding of Terms
water bodies
types
categories
The Task

3. Objectives
To establish a common framework for typology of transitional and coastal waters across the North East Atlantic Ecoregion Complex (Annex XI)
Atlantic Ocean
Norwegian Sea
Barents Sea
North Sea

4. Objectives (continued)
To identify the key option factors in Annex II to define a physical typology system that is ecologically relevant.
To inform the ecoregion workshops for the Baltic and the Mediterranean Workshops in December.
To enable typology guidance to be finalised by January 2002.

5. Compare like with like Typology
Physiological types that are ecologically relevant
Ecological quality:-
Compare like with like

6. How did we get here? Conclusions Brussels Workshop, September, 2001
System B (with the exception of MSs with very simplex coastline)
Biggest factor to differentiate ecoregion types is salinity and tidal regime (simplex/complex)
Baltic
North East Atlantic
Mediterranean
To develop guidance further - ecoregion level

7. Principles agreed….
As simple a typology as is practicable and ecologically relevant
Number of types NE Atlantic? (10-20)
10 too few
50-60 too complex
It is recognised that a simple typology will need to be countered with ranges in reference conditions

8. Reference Conditions
EuroTypes A B C E D
The European Sea

9. Need for Common Understanding:
Water bodies
Water body categories (transitional & coastal)
Water body types
Scale??

10. Surface Water Bodies
Body of surface water means a discrete and significant element of surface water such as a lake, a reservoir, a stream, river or canal, part of a stream, river or canal, a transitional water or a stretch of coastal water.
Classification/management unit of the Directive
Smallest unit of Directive

11. Surface Water Categories:
Surface water bodies within the RBD shall be identified as falling within either one of the following surface water categories - rivers, lakes, transitional and coastal water - or as artificial surface water bodies or heavily modified surface water bodies
Surface water categories - transitional or coastal water bodies

13. Surface Water Types
For each surface water category, the relevant surface water bodies within the river basin district shall be differentiated according to type. These types are those defined using either system A or system B identified in section 1.2.
Types -
Annex II
system A or system B

14. Category: Transitional Water
Type: N-E Atlantic Muddy Estuary
Category: River
Type: Lowland Calcareous
Category: Coastal Water
Type: Exposed, shallow
Gravel / Sand

15. Surface Water Bodies
Body of surface water means a discreet and significant element of surface water such as a lake, a reservoir, a stream, river or canal, part of a stream, river or canal, a transitional water or a stretch of coastal water.
Classification/water management unit of the Directive

16. Industry
Category: Transitional Water
Type: N-E Atlantic Muddy Estuary

17. Industry
Category: Transitional Water
Type: N-E Atlantic Muddy Estuary

19. Brussels Question?
Why not identify this as two separate physical types
inner NE Atlantic muddy estuary
outer NE Atlantic muddy estuary
Do we need lots and lots of types to meet the objectives of the Directive?

20. i.e. Good Status Spirit of the Directive is to concentrate effort
on water bodies that are not meeting ecological objectives
i.e. Good Status

21. Brussels Question? Can a water body be bigger than a type?No
Because the reference conditions are specific to each type
Classification/management unit of the Directive
Smallest unit of Directive

22. The Task To develop a common framework for typology
Presentations on progress to date
Presentations on other possible approaches
Identification of the key optional factors
How should key optional factors be used
