After processing, the datasets were published via HELCOM Map and Data service as individual map layers. Dataset corrected in January 2019: Upon request of the data provider outputs have been updated by ICES to better ensure vessel anonymity. Three ICES advice products (associated with sr.2018.14, sr.2017.17, and sr.2017.18) that use VMS and logbook data to describe detailed bottom trawling fishing activity have been updated to better ensure individual vessel anonymity. For these products, the level of gear grouping dis-aggregation at a c-square resolution of (0.05 degrees x 0.05 degrees) over one year were deemed too detailed by the original data provider subsequent to the release of the original advice. For these c-squares (containing 3 vessels or less) the value "-9" has been inserted to indicate that the data value for effort is missing from the c-square, but that the c-square does have a footprint from bottom trawling.

Use constraints: Data can be used freely given that the source is cited (following creative commons license CC-BY). The source should be cited as: “HELCOM HOLAS 3 Dataset (2023)"
The dataset was created in order to update the information for the indicator under HOLAS 3. Following a data call submitted to Contracting Parties in April 2021. HELCOM HOLAS III Data call covers all current regular monitoring data reporting as well as supplemental data that is required for the State of the Baltic Sea report.
The occurrence of suitable nursery habitats is crucial for maintaining fish populations (Sundblad et al. 2013). For perch, species distribution modelling studies (Snickars et al. 2010, Bergström et al. 2013, Sundblad et al. 2013) have shown the importance of suitable environmental conditions for reproduction. Due to lack of coherent data on perch spawning and nursery areas across the Baltic Sea countries, environmental variables were used in delineating potential recruitment areas for perch. The distribution area or perch recruitment is delineated by selecting areas where depth < 4 m (For Danish waters < 3 m), logged exposure < 5 (exposure model described in Isæus 2004), and salinity < 10 PSU. The threshold values have been obtained from literature (Snickars et al. 2010, Bergström et al. 2013, Skovrind et al. 2013, Sundblad et al. 2013). Relatively “loose” thresholds have been used, to rather overestimate than underestimate the recruitment area (precautionary approach). Along the Finnish coastline a national model has been used (Kallasvuo et al. 2016), with suitable environments for perch recruitment generalized to 1 km x 1 km grid.
Use constraints: Data can be used freely given that the source is cited as "HELCOM HOLAS II Dataset: Perch recruitment area (2017)".
Data source: Depth: Baltic Sea Bathymetry database (http://data.bshc.pro/#2/51.8/20.1), complemented in some coastal areas with IOW bathymetry data (Seifert et al. 2001). Wave exposure: Wave Impact Index calculated for the whole Baltic Sea (Isaeus 2004) Salinity: Monthly means of May for years 2011-2014 downloaded from Copernicus Marine Environment Monitoring Service (http://marine.copernicus.eu). Reanalysis products of SMHI for years 1989-2004, 5.5km grid cells. A May mean for 2011-2014 was calculated. Extrapolation to some coastal areas (that were outside the original data due to low resolution of the grid) was carried out.

Data quality: The map is based on literature and environmental variables, not actual data. Also the data layers on environmental variables are based on modelling. The species distribution modelling studies, where the thresholds values for environmental variables have been obtained, are mainly from the northern Baltic Sea. Here, the same thresholds have been applied in the southern Baltic. Due to these constraints, the perch recruitment area map should be considered as a rough estimation. The dataset was approved by all HELCOM Contracting Parties in the HOLAS II Ecosystem component data review process during first quarter of 2017 after corrections from Denmark. Attribute information: Raster value representing the potential occurrence of perch recruitment area (either 0 or 1).

Metals - Lead in sediment results HOLAS 3
This core indicator evaluates the status of the marine environment based on concentrations of heavy metal Lead (Pb) in sediment. Quantitative thresholds are used to classify core indicators status in “Achieve”, “Fail” or “Not assessed”. Threshold values are based on Environmental quality standards (EQS), defined at EU level for substances included in the priority list under the Water Framework Directive. This dataset displays the result of the indicator in HELCOM Assessment Scale 4 (Division of the Baltic Sea into 17 sub-basins and further division into coastal and off-shore areas and division of the coastal areas by WFD water types or water bodies). Attribute specifications and units: "HELCOM_ID" = Code of the HELCOM scale 4 assessment unit "country": country in which the HELCOM assessment unit is located or a mention to an open sea area "level_2" = Name of the HELCOM assessment unit in scale 2 "Name" = Name of the HELCOM assessment unit in scale 4 "Open_sea" = Name of the HELCOM assessment unit in the open sea "F2_Name" = Name of the HELCOM assessment unit "determinan" = Determinat "est" = The estimated mean loge concentration in the assessment unit "se" = The standard error on the estimated mean log concentration in the assessment unit "fit" = The estimated mean concentration in the assessment unit "upper_cl" = Upper one-sided 95% confidence limit on the mean concentration: exp(est + qnorm(0.95) * see) "Status" = Overall Status of the indicator according to one-out-all-out
The indicator is based on data held in the HELCOM COMBINE database, hosted at the International Council for the Exploration of the Seas (ICES). All available data on lead in water, fish liver and bottom sediments up to 2021 were used. Evaluation is carried out using an agreed R-script that runs a statistical analysis. The overall confidence of the indicator evaluation is high. Additional information: http://www.helcom.fi/baltic-sea-trends/indicators/metals/
