Number of hunted cormorants (Phalacrocorax carbo) per year per county. A total sum and a calculated average (hunted individuals / year) is given for the time period 2011-2015. The data was made available by HELCOM Contracting Parties in response to data request. The data was received from Denmark, Estonia, Finland and Sweden. The activity was declared as not relevant in Germany, Lithuania and Poland. From Latvia and Russia no data was reported. Attribute specification and units: Country: Country County: County SUM: Total number of hunted individuals during 2011 – 2015 AVERAGE: A calculated five (or four) year average of hunted cormorants per year (hunted individuals/year) 2011 – 2015: Number of hunted cormorants in the year in question

This dataset contains all HBCD in biota monitoring station locations, observed matrix, biota matrix and monitored species as reported to HELCOM secretariat by HELCOM Contracting Parties by 2016.

This dataset contains all HBCD in seawater monitoring station locationsas reported to HELCOM secretariat by HELCOM Contracting Parties by 2016.

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.

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 “circalittoral mixed substrate” includes classes “mixed sediment” of the original data, in the circalittoral 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.

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 sand” includes classes “Sand” and “Muddy sand” of the original data, in the infralittoral zone. The original polygon maps have been converted to 1 km x 1km 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).

This dataset contains all heavy metal monitoring station locations, observed matrix, biota matrix and monitored species as reported to HELCOM secretariat by HELCOM Contracting Parties by 2016.

Locations of the coastal protection structures. The dataset contains information about the coastal defence structure type and for some the structure length (m) and the year of construction. The data was made available by HELCOM Contracting Parties in response to data request. The data was received from Denmark, Estonia, Germany, Finland, Poland and Sweden. The activity was declared as not relevant in Lithuanian area. From Latvia and Russia no data was reported. Attribute specification and units Country: Country Type: Modification structure type Const_year: Year of construction Estimated: Estimated date of completion if under construction (Estonia) or the year of environmental permit if year of construction is lacking (Finland) Out_of_use: Year when costal defence structure has been taken out of use Measure: Additional information about the modification structure Length: Length of the modified coastline (m) width: Width of the modification structure (m) Area: Area of the modification structure (km2) X_Lon: Original X (Longitude) coordinate point (Finland)

Location of water course modifications (trenching, culverting, canalisation). The data was made available by HELCOM Contracting Parties in response to data request. The data was received from Estonia, Finland and Poland. Data reported by Finland and Poland as water course modification were interpreted as pipelines and were included in HELCOM HOLAS 2 Pipelines dataset. The activity was declared as not relevant in Germany and Lithuania. From Latvia, Russia and Sweden no data was reported.

This dataset contains all heavy metal monitoring station locations where seawater samples are analysed. The information is based on data reported to HELCOM secretariat by HELCOM Contracting Parties by 2016.
