  • Nutrient monitoring activities in the Leningrad and Kaliningrad regions have been implemented within BASE Project. BASE supports the implementation of the Baltic Sea Action Plan (BSAP) in Russia. The monitoring pilot project is focused on the assessment of the nutrient loads coming to the Baltic Sea from Russian part of the catchment. The main activities within the pilot project include nutrient sampling and flow measurements in the river Neva catchment (downstream outlet from Lake Ladoga) and in the water objects of Kaliningrad region (Pregolya and its tributaries, other rivers of Vistula and Curonian Lagoon etc.). More information about results can be found from the BASE Project final report from the HELCOM website.

  • Eutrophication, caused by excess inputs of nutrients, is one of the main threats affecting the Baltic Sea marine environment. Nutrients enter the Baltic Sea as waterborne (riverine inputs from the catchment area and direct discharges from point and diffuse sources in coastal areas) and airborne (atmospheric deposition) inputs. In 2007 HELCOM adopted a nutrient reduction scheme which is based on maximum allowable nutrient inputs (MAI) to reach "good environmental status" and country-wise nutrient reduction targets (CART) to share the burden of reducing nutrient pollution to the sea (HELCOM Baltic Sea Action Plan). Monitoring of nutrient inputs to the sea is important for assessing progress of countries towards their CART and to evaluate the effectiveness of measures to reduce pollution. This dataset displays total normalized annual average phosphorus loading as produced for href="http://www.helcom.fi/baltic-sea-trends/indicators/inputs-of-nutrients-to-the-subbasins" target="_blank"> HELCOM Core indicator: Inputs of nutrients to the subbasins based on HELCOM PLC data. Green colour of PLC subbasin indicates that inputs during 2016 were lower than MAI, red colour when they were higher, while yellow indicates that when taking into account the statistical uncertainty of input data it is not possible to determine whether MAI was fulfilled. The dataset contains following attributes: Basin: Name of PLC Subbasin Maximum allowable nutrient input: Maximum allowable phosphorus input for the subbasin (tons/year) P input including statistical uncertainty 2016: the average normalized phosphorus input during 2016 (tonnes/year) including statistical uncertainty for the subbasin Input 2016 including stat. uncertainty in % of MAI: proportion of average normalized phosphorus input during 2016 compared to MAI Classification of achieving MAI: Classification of achieving MAI is given in colours: green=MAI fulfilled, yellow= fulfilment is not determined due to statistical uncertainty, and red=MAI not fulfilled.

  • This dataset consists of information and status of the main pollution sources within the Baltic Sea catchment area (the Pollution Hot Spots). The HELCOM pollution Hot Spots were idenitified in 1992 by the HELCOM Joint Comprehensive Action Programme (more information is available on www.helcom.fi). The current status of active and cleaned hot spots is available https://helcom.fi/action-areas/industrial-municipal-releases/helcom-hot-spots/.
