The data set contains information on the location of individual turbines of the offshore wind farms in the Baltic Sea area. In addition to information on the location of the wind farms, the following information is included: Name, Country, Status (Generating power or under construction), Company, Capacity MW (whole park), number of turbines (whole park), construction year and source.

The dataset contains information on the location of individual turbines in place or planned location for offshore wind farms in the Baltic Sea area as reported by the Contracting Parties for the period 2016-2021. The data was made available by HELCOM Contracting Parties in response to a data call. The data was reported by Denmark, Finland and Germany. The activity was declared as not relevant in Estonia and Latvia. The use of HOLAS 2 data was requested by Sweden. Attribute specification and units with predefined values specified from the data call: Name: Name of the wind farm Status: Status of the wind farm (operational, under construction, application submitted, planned, approved, other) Company: Operation company name CCapacity: Current capacity of the whole wind farm in megawatts (MW) PCapacity: Planned capacity of the whole wind farm in megawatts (MW) CN_turbine: Current number of turbines in the whole park PN_turbine: Planned number of turbines for the whole park Start_year: Year when the construction of the turbine started End_year: Year when the construction of the turbine ended Foundation: Foundation type (monopile, gravity, tripod, tripile, jacket, floating, other) Scour_prot: Scour protection Trans_L: If transformer, the length of the transformer in meters Transf_W: If transformer, the width of the transformer in meters Sediment: Sediment type (mud, sand, hard substrate, mixed sand, other) Notes: Notes regarding the data country: Country that reported the data Status_original: Original status declared by the Contracting Parties

The dataset contains cables in the marine environment that was made available by HELCOM Contracting Parties in response to a data call. Data were reported by Estonia, Denmark, Finland, Germany, Poland and Russia for the period 2016-2021. Attribute specification and units with predefined values specified from the data call Name: Name of the pipeline Type: Type of the pipeline (water, oil, gas, effluent, other) Diameter: Diameter of the pipeline Unit: Unit of the diameter Status: The status of the pipeline harmonized with the values from a predefined list (operational, under construction, application submitted, planned, approved, other), and following a precautionary approach that attributed the value operational for values that were out of the predefined list Start_year: Year when the construction of the pipeline started End_year: Year when the construction of the pipeline ended Pipe_prot: Specification of the type of pipeline protection (none, sand, hard substrate, mixed sand, other) Sediment: Sediment type (mud, sand, hard substrate, mixed sand, other) Pipe_posit: Specify the position of pipeline in the seabed (in the sediment, on the sediment) If pipeline position is 'in the sediment': Lay_Depth: Laying depth in meters Refilling: Refilling of the trench (YES/NO) Method: Method utilized when laying the pipeline Pipe_width: Width of pipeline trench in meters Notes: Notes regarding the data Status_original: Original status declared by the Contracting Parties

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.

Total (monthly, and 5 year average) discharge from hydropower dams (m3/s). Data includes the water that passes the turbines as well as the water not passing the turbines. The data was made available by HELCOM Contracting Parties in response to data request. The data was received from Estonia, Finland and Sweden. The activity was declared as not relevant in Denmark, Germany, Latvia, Lithuania and Poland. Data contains only those hydropower dams that are situated closest to the Baltic coast (less than 40 km), are the first ones from the coast in the river network and have a direct connection to the Baltic Sea trough river. Swedish data is a combination of actual measurements and modelling. Modelled data have been calculated with s-hype2012_version_3_0_0. These data are also presented online at http://vattenwebb.smhi.se/regulations/. Please note that data from 2015 is provisional and may be subject to revisions. Attribute specification and units: X_Long: X (East) coordinate point Y_Lat: Y (North) coordinate point Country: Country (EE=Estonia, FI=Finland, SE=Sweden) ID: Name or ID number of the hydropower dam AVG_year: A calculated yearly average discharge (m3/s) (2011-2015) jan_2011 – dec_2015 : Monthly discharge (m3/s)

Dataset contains the vessels in the Baltic Sea area with towing capacity in an emergency situation (over 25 tons of bollard pull). The locations of the ships are approximate, derived from the homeport of the vessel.

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.
