Baltic Sea Pressure Index HOLAS 3
The Baltic Sea Pressure index (BSPI) assesses the potential cumulative pressures in the Baltic Sea. The BSPI is based on georeferenced datasets of human activities (28 datasets), pressures (17 datasets) and uses the average sensitivity of each pressure layer to all ecosystems to weigth the pressure. Cumulative pressures are calculated for each assessment unit (1 km2 grid cells) and the data set covers the time period 2016-2021.
Spatial Pressure and Impact Assessment (SPIA) is the framework for assessing spatial and cumulative pressures and impacts in HOLAS 3, where the BSPI presents the full cumulative pressure assessment where all pressures are included. The framework also includes results for the Baltic Sea Impact Index (full cumulative impact assessment), and other thematic assessments where a subset of pressure and ecosystem layers are used.

- visit the HOLAS 3 website ( http://stateofthebalticsea.helcom.fi/)
- download the report thematic assessment of spatial distribution of pressures and impacts 2016-2021 ( https://helcom.fi/post_type_publ/holas3_spa)
- or check out the HELCOM SPIA online tool to make calculations for any desired combination of pressures and ecosystem layers ( https://maps.helcom.fi/website/bsii/).

The BSPI assessment is based on the method created by Halpern et al. (2008), and it's using the sum method where all individual calculations for all pressures are summed to get the final value for the cell. The assessment was carried out using a gridded approach with a resolution of 1 square kilometre.
The assessment was first applied in the Initial HELCOM Holistic Assessment of Ecosystem Health, and was developed further in several projects during HOLAS 2 and in the MetDev project during HOLAS 3.
Data source and quality:
See separate metadate records aggregated pressure layers and human activities.
Attribute information:
Index value indicating the combined potential cumulative pressure, resulting from the formula used to calculate the index.
Spatial coverage: Entire Baltic Sea
Spatial resolution: Original data in various formats and resolution, here 1 km x 1 km grid.
The assessment was carried out using the SPIA tool designed by the HELCOM Secretariat in the Pan Baltic Scope project and further developed in the HELCOM MetDev project.
