Eutrophication assessment data workspace 2018 version

Project Summary

This workspace and dataview​ will be used by experts for verifying the reported data to COMBINE database which will be used for HELCOM HOLAS II Eutrophication assessment.

If there is any questions related to the review or the workspace, contact HELCOM Secretariat (joni.kaitaranta@helcom.fi)


Eutrophication assessment proc​ess

Eutrophication is assessed by HELCOM using regularly monitored data provided by the contracting parties to produce an indicator-based quantitative assessment. The Contracting Parties to HELCOM are responsible for producing the assessment, with ICES acting in the role of data host for COMBINE database.


Expert review of data and assessment products​​

To ensure a high quality of the data and the assessment of the eutrophication indicators a checking procedure has been agreed and will be followed by experts in the HELCOM Eutrophication Network. Each country is responsible for checking their datasets and the assessment of their coastal waters and coordinate nationally the review process. Detailed instructions on the checking procedure can be found in Annex 2A of the Eutrophication Assessment Manual.

The review is done in this workspace, under national pages, where experts have been provided with rights to relevant pages. The assessment data can be viewed at the 'Dataview​' -page, under separate sheets for Accessions, Stations, Indicators and Assessment. For checking purposes, data may also be downloaded from the dataview, to permit viewing in any selected programme.
