Potential effect of continuous noise to mobile species HOLAS 3
Potential effect of continuous noise to mobile species assesses the cumulative potential effect of continuous noise on mobile species and their presence in the HELCOM area. The evaluation is based on the pressure layer on input of continuous noise, combined with information on the distribution of 15 mobile species and their habitats. The thematic analyses on the potential effect of continuous noise to mobile species is 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, and this analyses present a thematic assessment including only a certain subset of layers. The framework also includes results for the Baltic Sea Impact Index (full cumulative impact assessment), Baltic Sea Pressure Index (full cumulative pressure assessment), and other thematic assessments where a subset of pressure and ecosystem layers are used.

- 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 cumulative aspect of this assessment is based on the method created by Halpern et al. (2008), and it's using the sum method where all individual calculations for the pressure - ecosystem combinations 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.
This assessment uses as input data the input of continuous noise ( https://metadata.helcom.fi/geonetwork/srv/eng/catalog.search#/metadata/d1cf5bda-fed2-4f54-a3c2-af701ed3a397) as pressure layer and 15 selected ecosystem components covering mobile species and their habitats (distribution of marine mammals, abundance of cod, herring and sprat, and the spawning, nursery and recruitment areas for fish).
Data source and quality:
See separate metadate records aggregated pressure layers, human activities and ecosystem component layers.
Attribute information:
Index value indicating the combined potential cumulative impact, 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.
