This challenge handled the ability to compute annual water discharges for each river bordering the sea basin, inputs of fresh water, sediment loading, total nitrogen and phosphates (time series), to assess whether the available marine data sets that had been available and appropriate to the use case, as well as to indicate gaps in the EU data collection framework.
The River Inputs challenge attempted to estimate, for each river bordering the sea basin, the time series of annual inputs:
- Mass of fresh water discharged and temperature
- Sediment load
- Fluxes of total nitrogen and phosphates
- Biota to sea as eels and salmon (both inwards and outwards, recruitment and escapement).
Nine different products were considered in order to provide an estimate of the amount of monitored rivers regarding the total number of rivers. (A river was defined by either by its river outlet (geographic position) or by the basin district, a region or a whole country).

Access to challenge products
Nine products are made available by ACRI-HE and AZTI for the River Inputs challenge as the result of the assessment exercise carried out for the EU Atlantic checkpoint project (DG MARE contract, 2015-2018). The products are listed and accessible from the table given below. All products are representative of Jjune 2017 status. There is no vertical dimension.
The challenge partners ("the producers") were commissioned to perform a number of tests to evaluate marine data according to set user requirements. The table below enables:
- to discover :
- the Data Product Specifications (DPS) which describe data products in terms of user requirements according to ISO19131 principles and provide the basis for the quantitative assessment of the Products (Quality measures and scope of application) and of the Upstream Data sets supplied to- and used by- the challenges to create them.
- the Results (TDP) which describe the Data Product created together with the quantitative assessments (Quality measures and indicators) and the expert opinion. - to download the products (shapefile, excel, pdf) on an "as is" basis. All downloads suppose acceptance of the use limitations described in the “Expert opinion” and the “Legal constraints” accessible using the link to the Results.
to view the spatial data products (Maps) using a webGIS.
Data product were scored by experts from 1 to 5, resp. inadequate to excellent. The score is mentioned in the last column. “Good” means the Product was achieved to at least 50% of the requirements. “Inadequate” means “Impossible to produce or fails to meet all the objectives (not usable)”.
