  • This dataset contains all heavy metal monitoring station locations where sediment is samples are analyzed as reported to HELCOM secretariat by HELCOM Contracting Parties by 2016.

  • The amount of collected mussels with dredging. Data is presented from the Danish mussel areas within the HELCOM marine areas. The data was made available by HELCOM Contracting Parties in response to data request. The data was received from Denmark. The activity was declared as not relevant in Estonia, Finland, Latvia, Lithuania, Poland, Russia and Sweden. Germany indicated that data is not available. Attribute specification and units: Nr: Identification number of the mussel area Name: Name of the mussel area BluMusl05 – BluMusl15: Amount of Blue mussel (kg) collected per year ComCockl05 – ComCockl15: Amount of Common Cockle (kg) collected per year Sum_BMus: Total amount of collected Blue mussel in 2005 to 2015 (kg) AVG_BMus: A calculated average of the collected blue mussels in 2005 – 2015 (kg/year) AVG_2_BM: A calculated average of the collected blue mussels in HOLAS2 period 2011 – 2015 (kg/year) Sum_ComC: Total amount of the collected common cockles in 2005 – 2015 (kg) AVG_ComC: a calculated average of the collected common cockles in 2005 – 2015 (kg/year) AVG_2_ComC: A calculated average of the collected common cockles in HOLAS2 period 2011 – 2015 (kg/year) Area: The mussel area within the dredging occurs (km2)

  • The shipping density map highlights the intensity of all IMO registered ships operating in the Baltic Sea. It is based on the HELCOM AIS (Automatic Identification System) data. The HELCOM AIS dataset contains all the AIS signals received by the Baltic Sea States since 2005. The data was pre-processed by the HELCOM Secretariat (under the Baltic SCOPE project) in order to have a dataset that could be used to generate products such as density maps and traffic statistics.

  • Data for Furcellaria harvesting presenting the amount of dredged tonnes per unit area per year. The data was made available by HELCOM Contracting Parties in response to data request. The data was received from Estonia. The activity was declared as not relevant in Denmark, Germany, Finland, Latvia, Lithuania, Poland, Russia and Sweden. Attribute specification and units: Dredged_ar: Furcellaria dredging area (km2, ND = no data available) Area: Area (fishing area) within dredging occurs (km2), area do not represent actual dredging area. 2011 - 2015: Amount of dredged Furcellaria (tonnes / year) Total: Amount (Sum) of dredged Furcellaria during 2011-2015 (tonnes) Average: Calculated annual average of the amount of dredged Furcellaria (tonnes/year)

  • Dataset represent urban land use (urban areas) around Baltic Sea coast. The resolution of the data is 250 m x 250 m. The dataset is constructed from CORINE Land Cover (CLC) 2006 for EU countries and from Open street map (OSM) open source data in Russia. Dataset is based on data collated for the HELCOM Second Holistic Assessment of the Ecosystem health of the Baltic Sea. The dataset covers the whole catchment area of the Baltic sea.

  • Mudflats and sandflats not covered by seawater at low tide (according to Habitats Directive Annex I) are often devoid of vascular plants, usually coated by blue algae and diatoms. They are of particular importance as feeding grounds for wildfowl and waders. The distribution map is based on data submission by HELCOM contracting parties. Only Denmark, Germany and Estonia reported occurrences of mudflats and sandflats. Most of the submitted data is based on modelling and/or GIS analysis. Data coverage, accuracy and the methods in obtaining the data vary between countries.

  • Broad-scale habitat maps for the Baltic Sea have been produced in the EUSeaMap project in 2016. For German and Estonian marine areas, national (more accurate) datasets were used. German data included both substrate and light information (division into infralittoral/circalittoral). Estonian data included only substrate and the division into light regimes was obtained from the EuSeaMap data. Here, the habitat class “infralittoral hard substrate” includes classes “Rock and other hard substrate” and “Coarse substrate” of the original data, in the infralittoral zone. The original polygon maps have been converted to 1 km x 1 km grid. The scale of the substrate data used in broad-scale habitat maps varies from 1:250 000 to 1:1M (data from EMODnet Geology). Coarser resolution data has been used in areas, where 1: 250 000 substrate data has not been available. Due to different scales used, the habitat classes may show different sized patterns in different areas.

  • The dataset contains the location of fossil fuel energy production facilities derived from the European Pollutant Release and Transfer Register (E-PRTR). E-PRTR cover all HELCOM Contracting Parties except Russia. Attribute specification and units: See E-PRTR code lists at https://www.eionet.europa.eu/schemas/eprtr/listOfValues In the HELCOM data review process, some facility locations appeared to be spatially slightly misplaced, adding up to uncertainty of data products derived from this dataset.

  • This dataset contains point data describing the location of oil platforms in the Baltic Sea. The dataset is complete in Baltic sea coverage as it contains two known oil platforms.
