1. CW-TW Intercalibration work progress
Fuensanta Salas Herrero, CW-TW IC Coordinator
Warsaw, March 2016

2. CW-TW IC draft results
2. Remaining issues

3. FROM THE LAST ECOSTAT MEETING, 7 WORKING GROUPS HAVE ALMOST COMPLETED THE INTERCALIBRATION
BALTIC GIG PHYTOPLANKTON (Common types BC4,BC9)
BALTIC BENTHIC INVERTEBRATES (Common type BC5)
NEA GIG SEGRASSES (Common type NEA 1/26)
NEA GIG CW PHYTOPLANKTON (NEA 1/26, NEA 7, NEA 3/4

4. BALTIC SEA GIG PHYTOPLANKTON
BC4 (EE,LV)
Harmonisation on Clh a boundaries completed.
Clh a data
Pressures data (TN and TP)
EE: 44 Samples (June-Sept)
LV: 92 samples (June-Sept)

COMPARABILITY ANALYSES
National boundaries exceeding a biass of 0.25 class equivalents should be adjusted to fall inside this permitted level of deviation. The boundary biass analysis showed that boundaries adjustments are not neccesary

Draft Report provided
Once the final report is completed will be sent to review panel (may be it is not necessary)

9. BALTIC SEA GIG PHYTOPLANKTON
BC9 (EE,FI,SE)

13. Comparison of data set for common period (July-August)

15. Along the SE coast, the northern stations have lower salinities as a result of influence from south-ward current from the Bothnian Sea.
Along the FI coast, the eastern stations have the lowest salinities, reflecting influence from the Gulf of Finland. Thus, the different freshwater sources can explain these very different gradients.
Importantly, it can be assumed that the influence from the Gulf of Finland has a stronger anthropogenic component than the influence from the Bothnian Sea. However, part of the influence from the Gulf of Finland may also be natural.

Justifications provided for not changing reference conditions and boundaries
To be reviewed by the review panel

17. BALTIC SEA GIG BENTHIC INVERTEBRATES
BC5(LV,LT, PL)
Poland has not participated (only one station/three samples)
LT-LV: Same method (BQI), but different boundaries

19. Physico- chemical data
Data set overview MS
Biological data
Physico- chemical data

83 data LV
119 data

20. BC5
Benchmark standarisation: Alternative benchmark sites (>15).
The national assessments only differ at (relatively) undisturbed conditions but converge at the more disturbed end, so, each national EQR value was divided by the median of the EQR at benchmark sites of the subtype from which the data originate.

21. Comparability analyses: IC Option 3
National boundaries exceeding a bias of 0.25 class equivalents should be adjusted to fall inside this permitted level of deviation.
No adjustments are necessary

22. NEA GIG CW-TW SEAGRASSES

25. Continuos benchmarking

26. Comparability analyses: IC Option 3

27. Boundaries adjustments proposed, but it is neccesary to check again the results
It is neccesary to introduce corrections in the technical report
All MSs shoul fill in the information requested in the technical report

28. NEA GIG CW harmonization Clh a

29. BALTIC GIG
CW Phytoplankton (Common types BC1, BC6)
BC6:Work completed, they have to provide the technical report
BC1: work in progress/end May
CW Benthic invertebrates (BC7): work in progress/end May
TW Phytoplankton (BT1): Work completed, they have to provide the report
TW Fish: Methods developed and validated but it is necessary more data (Ic in the future)

30. BALTIC GIG
TW Macrophytes: Justifications for not intercalibrating
TW Benthic invertebrates: Working for the development of methods

31. NEA GIG
1.TW Phytoplankton harmonization of Clh a boundaries
2. CW-TW Seagrasses: draft report provided but results have to be checked
3. CW Benthic Invertebrates (Common type 3/4): Work completed but it is still necessary the MSs agreement
4- TW Benthic invertebrates: Difficulties with standardisation-Continuos benchmarking- no common pressure parameter.
5- Saltmarshes: Expected results end May

32. MED GIG
1.MED GIG Type IIIE: Report provided but results have to be checked.
2. MED GIG TW Fish (IT-GR):
Italy has developed a WFD compliance method, and already validated
GR method is still under development (deadline for providing the method-30 April)
