The two-year project on
‘Making HELCOM Eutrophication assessments operational (HELCOM EUTRO-OPER)’ was
finalized in 2015. During this time, the project developed an operationalized
work flow for updating the eutrophication indicators and assessment. Four out of the five
existing HELCOM CORE indicators of eutrophication were included into the
process algorithms. The complex oxygen debt indicator, developed by the TARGREV
project, could not be included without additional expertise and funding within
the EUTRO-OPER timeframe. This indicator, however, has been seen useful to be
updated for HOLAS II.
EUTRO-OPER developed six PRECORE
or candidate indicators of eutrophication. Of these, the cyanobacterial bloom
and the shallow water oxygen indicators could be updated to CORE status with
reasonable expenses striving to be in time for them to be included to the HOLAS
II. The cyanobacterial bloom indicator requires testing and developing for
combining it with the existing environment fact sheet on cyanobacteria biomass.
The shallow water oxygen indicator approach should be determined through
testing existing procedures and boundaries.
HELCOM HOD 49-2015 welcomed
the outcome of the EUTRO-OPER project and took note that the pre-core (candidate)
indicators investigated and developed by EUTRO-OPER will not be finalized by
end of the project and that in order to finalize them Lead Countries are needed
to ensure their continued development as well as resources for modelling to
develop GES-boundaries for three of the indicators. The Meeting noted the view
of Finland, Germany and Sweden to continue the project in 2016 with support of
a part-time project manager. The Meeting agreed to continue the project for a
limited period and welcomed the offer by Germany to contribute to the work
The project activities will
contribute to the work of the International Network on Eutrophication according
to the agreed Terms of Reference and the work plan.
3. To make HEAT 3.0 ready for the use for HOLAS II
4. Management and coordination to support the tasks above and to support the commencing of IN-Eutrophication regarding the tasks in the work plan Expected results The project will include the oxygen debt CORE indicator into the eutrophication assessment work flow. The indicator procedure developed by the TARGREV project (Århus University) will be translated from SAS-language into R-based algorithms that work in connection with the ICES database, as the other new eutrophication assessment algorithms. As a result, the project will deliver an updated work flow with the core indicators fully operational, to be used in the HOLAS II project for updating the eutrophication assessment in 2017.The project will finalize the eutrophication PRE-CORE indicator on cyanobacterial blooms and the candidate indicator on shallow water oxygen. For the former, the present approach will be developed further to include the cyanobacteria biomass indicator, applying data already provided by the PEG group. The existing methodologies for determining shallow water oxygen status will be tested and developed further in order to determine a common approach, using data from testing sites provided by ICES and the Contracting Parties.
The 'Project on making HELCOM eutrophication assessments operational (EUTRO-OPER)' aimed toward a regularly updated high-quality thematic assessment of eutrophication status, produced through an operational and streamlined process. It was a continuation to the CORE EUTRO process, stemming from the EUTRO-, EUTRO PRO- and TARGREV projects, which have since 2005 developed the HELCOM core set of eutrophication indicators, with boundaries of good environmental status and assessment methodology, ending up in the latest update of eutrophication status in the Baltic Sea in 2007-2011.
The EUTRO-OPER project piloted the production of assessment products through efficient data flow processes. During the project, the entire assessment process, from monitoring and data aggregation to assessment calculation, was defined and documented, together with the protocols as well as responsibilities of QA/QC guidance and review. The project continued to improve the quality of the existing eutrophication status core indicators through enabling use of remote sensing and ship-of-opportunity data. Gaps in the present set of core indicator were investicated and new indicators were proposed. In addition, steps toward coordination of harmonizing the coastal and open sea eutrophication assessment were taken.
1. Fully operational eutrophication assessment work flow with documented review process.
2. Four new pre-core and two new candidate indicators of eutrophication.
3. Proposal for approach for including new data types with high spatial or temporal resolution into the update of core indicators, with implementation on the update of chlorophyll-a using both in-situ and satellite data.
4. Proposal for including satellite based earth observation data (EO-data) in the update of the chlorophyll-a indicator.
5. Proposal for improved harmonization of coastal and open-sea assessments, through testing and implementing HEAT 3.0 for coastal assessment units and including coastal indicators into the assessment work flow.
6. Proposal for visualizing distance to target in the eutrophication assessment and eutrophication indicators.
7. Core indicator web-reports, updated for the 2007-2011 assessment.
8. Input to the HELCOM Monitoring Manual, through filling information on eutrophication-related monitoring parameters.
