By default, the integrated ecological status assessment is made using all available modelled indicator parameters.
It is also possible to exclude individual indicators or groups of indicators from the aggregation process to investigate how this affects theintegrated status.
Do this by changing the selection of indicators in the table below.

aggregration between seasons the average EQR values are first calculated for summer and winter eutrophication indicators. The EQR for eutrophication is taken as the average of summer and winter values. Finally, the worst EQR value of eutrophication and organic determines the overall result for the Physical-Chemical quality element.
no aggregration between seasons the average EQR values are calculated for summer and winter eutrophication indicators. The overall Physical-Chemical EQR is given by the worst (lowest) of (i) organic, , (ii) summer and (iii) winter EQR values.
one-out all-out the EQR value for the Physical-Chemical quality element is given by the worst (lowest) individual EQR value from all supporting indicators. the aggregated Biological EQR value is given by the worst (lowest) individual EQR value from all biological indicators, without any averaging within quality elements
About this app
The work to develop this app was part of the MARTINI project ('MARTINI - Understanding and predicting water quality for ecosystem-based management of Norwegian fjords, coastal waters and seas'), funded by the Norwegian Research Council (Forskningsrådet) under the MARINFORSK program (Marine Resources and Environent).

This app is written in the R statistical programming language, using the 'Shiny' package. Results from the MARTINI biogeochemical model results (MARTINI800 Hindcast Archive 2017-2019) are used, showing spatial variation of ecologically relevant indicator parameters, representing both biological quality elements (phytoplankton, macroalgae and and benthic fauna) and supporting physico-chemical indicators (Secchi depth, bottom oxygen and nutrients).
Following the Water Framework Directive principles, the app aggregates estimated values of individual indicators to arrive at an overall ecological status in a selected waterbody. The user can investigate the the spatial variation of the indicator parameters as well as the resulting ecological status in coastal water bodies, expressed as an ecological quality ratio (EQR) determined by comparing simulated values of indicator parameters with official threshold values used to classify status of water bodies.
Coming developments of the application will include results of simulations under different scenarios such as nutrient load reductions. This will allow users to examine resulting changes in estimated indicator parameters under these scenarios and in the predicted ecological status.
