Abundance of salmon spawners and smolt HOLAS 3

This indicator evaluates the status of the Baltic Sea area based on salmon smolt production in rivers flowing into the sea, also making use of additional supporting data on numbers of adult spawners. Determination of whether the threshold value that determines good status is achieved is based on a comparison of estimated smolt production with an estimated potential smolt production capacity. This dataset displays the result of the indicator in HELCOM Assessment Scale 2 (Division of the Baltic Sea into 17 sub-basins). Attribute information: “SB_Code” = Code of the Helcom subbasin "Name" = Name of the Helcom scale 2 assessment unit "AREAKM2" = Area of the Helcom scale 2 assessment unit HELCOM_ID = Helcom id of the Helcom scale 2 assessment unit ICES_AU = ICES assessment unit number Threshold = Threshold Threshold_v = Threshold value for this indicator "Ind_value" = Value for the indicator in Helcom scale 2 assessment unit Status = Status of the indicator (“Good”, “Not good” or “Not assessed”) comment = additional info

This dataset contains core indicator results developed under the HELCOM Third Holistic Assessment of the Ecosystem Health of the Baltic Sea (HOLAS 3). "HELCOM_ID" = HELCOM assessment unit scale 3 ID "country" = Country "level_2" = Name of scale 2 HELCOM assessment unit "level_3" = Name of scale 3 HELCOM assessment unit "coastal" = Code of scale 3 HELCOM assessment unit "open_sea" = Name of the open sea area "SAUID" "SAUlevel" "SAU" "Indicator" = Indicator "ECID" = Ecosystem Component ID "EClevel" = Ecosystem Component level "EcosystemC" = Ecosystem Component "Status" = Status of the indicator (“Achieve”, “Fail” or “Not assessed”)

Abundance of seatrout spawners and parr HOLAS 3

This core indicator evaluates the status of coastal sea areas of the Baltic Sea based on the abundance of sea trout parr in rivers where they breed. The determination of whether good status is reached is based on a comparison of the observed parr densities in rearing habitats with the reference potential parr densities in the specified habitats. This dataset displays the result of the indicator in HELCOM Assessment Scale 3 (Division of the Baltic Sea into 17 sub-basins and further division into coastal and offshore areas). Attribute information: "HELCOM_ID" = ID of the HELCOM scale 3 assessment unit "level_2" = Name of the HELCOM scale 2 assessment unit "level_3" = Name of HELCOM scale 3 assessment unit "ICES Subdivision" = ICES assessment unit number "Area (km2)" = Area of the HELCOM scale 3 assessment unit "Indicator_" = Name of the indicator "Unit" = Unit of the indicator "Type" = 1 = boundary values increase/decrease monotonically, 2 = optimum range indicator "Status" = Status of the indicator (“Achieve”, “Fail” or “Not assessed”) "ConfA" = Confidence of classification "ConfT" = Temporal confidence of classification "ConfS" = Spatial confidence of classification "ConfM" = Methodological confidence of classification "notes" = additional info "AULEVEL" = Assessment unit level used for the indicator

Offshore spawning areas fish pelagic eggs (BRISK)

The data set is showing spawning areas with pelagic fish eggs in the Baltic Sea area as polygons used for the BRISK project (Sub-regional risk of spill of oil and hazardous substances in the Baltic Sea, http://www.brisk.helcom.fi/). This dataset has been produced by COWI (http://www.cowi.dk) based on data from HELCOM and COWI. Fish-egg and larvae are sensitive to oil dissolved in the water phase.
