Baltic Sea Pressure Index (BSPI)
The Baltic Sea Pressure Index is a calculation of quantity and spatial distribution of potential cumulative impacts on the Baltic Sea. The BSII is based on georeferenced datasets of human activities (36 datasets), pressures (18 datasets) and ecosystem components (36 datasets), and on sensitivity estimates of ecosystem components (so-called sensitivity scores) that combine the pressure and ecosystem component layers, created in http://www.helcom.fi/helcom-at-work/projects/holas-ii project.
The assessment can be applied with a focus on pressures only by using the Baltic Sea Pressure Index (BSPI) which shows the anthropogenic pressures/human activities in the defined assessment units without including ecosystem components. The BSPI however includes a weighting component in order to grade the effect of the pressures on the ecosystem in a generalized perspective. Cumulative impacts are calculated for each assessment unit (1 km2 grid cells) by summing all impacts occurring in the unit. All datasets and methodologies used in the index calculations are approved by all HELCOM Contracting Parties in review and acceptance processes. This dataset covers the time period 2011-2016.

The Baltic Sea Impact index (BSII) was first applied in the Initial HELCOM Holistic Assessment of Ecosystem Health
(HELCOM 2010a), building on concepts described by Halpern et al. (2008). The concepts were subsequently developed
further for the eastern parts of the North Sea by the HARMONY project (Andersen et al. 2013), which has developed
a HARMONY Pressure & Impact Mapper software (Stock 2016).
It was agreed during the HOLAS II process that the input pressure layers should be in numerical balance between different types of anthropogenic pressures, and therefore, human activity data layers being proxies for pressures should be aggregated when they reflect the same pressure. Temporal characteristics of the pressures are taken into account in the data processing, by designing the spatial data sets so that they more accurately represent cumulating or temporary pressures. These aggregated pressure layers follow the indicative list given in the Table 2a of the revised the Marine Strategy Framework Direction (MSFD) Annex III. More detailed information how these aggregation are made is available in the metadata of invidual datasets.
Baltic Sea Pressure Index has been calculated with a ArcGIS toolbox, developed at the HELCOM Secretariat, following the concepts described by Helpern et al. (2008).
