• Effects on human well-being/Cost of degradation
• Human activities and pressures acting on the

environment

– Spatial distributions – Trends – Socioeconomic importance – BSII outputs

• Measures towards reaching GES
• Conclusions and future outlook

Overview of HOLAS II outputs at different level of detail

• To be

presented online

Oil slicks and spills in the Baltic Sea 2003-2007 Description of the data The relative amount of oil spills and

• il slicks in 5km × 5 km grid cells. In

the map, the number of annual

• bservations per grid cell was

classified to four classes: 0 (no spills/slicks), 1 (1-3 observations), 2 (4-6 observations and 3 (>6 annual

• bservations). The annual data was

summed over the years 2003-2007 and therefore the relative scale of the map exceeds the 0-3 scale. Data source: HELCOM Annual report on discharges observed during aerial surveillance in the Baltic Sea (http://www.helcom.fi/action-areas/response-to-spills/publications/). Attribute information: Grid cell ID, Center coordinates of grid cells, relative amount of slicks and spills (class scale), original number of observations per year. Spatial coverage: Entire Baltic Sea. Spatial resolution: The original data shows actual observation sites but this data layer is aggregated to 5km × 5 km grid cells

• ver the Baltic Sea.

Time period and temporal resolution: Data is summed for the period 2003-2007 and is based on annuals data from the HELCOM aerial surveillance flights which operate around the year. Data access: HELCOM data and map service (http://www.helcom.fi/baltic-sea-trends/data-maps). Limitations of use: Data can be used freely given that the source is cited. Responsible institution: HELCOM (www.helcom.fi).

Thematic fact sheets

• Shows the spatial data sets used in the BSII

(pressures and ecosystem components)

• Presented online, including a method description on

how they were developed.

– To explore: should the sensitivity scores be presented in these sheets

• The spatial data sets are to be presented for approval
• ver a workspace

Technical fact sheets

• Technical information on all spatial data underlying

the analyses

• Metadata including data quality aspects
• For countries to accept via workspace.

– In some cases thematic fact sheets and technical fact sheets may contain identical information

Socioeconomic importance: Regional use of marine waters analysis

Economic indicators based on national statistics Presented for selected sectors To be developed further in the TAPAS ESA theme

Assessment of pressures in HOLAS II

– Cumulative spatial distribution of pressures and impacts on the Baltic Sea (this workshop) – Trends over time for selected pressures – Pressure core indicators

• 1. Spatial distribution of pressures and impacts
• Given by the Baltic Sea Pressure and Impact

Index

• The pressures to be included are aggregated

into themes, which may also be of interest to display separately

• 2. Trends over time for selected pressures
• May be obtained from ongoing HELCOM

reporting and assessments

– PLC for hazardous substances and nutrient loading (Annex 2) – ICES regarding the fishing mortality – Data sets reflecting physical or hydrological disturbance, long term time series are typically not available.

• 3. Pressure core indicators
• The HELCOM core indicators contains three pressure

core indicators, which are linked to pressures listed in EU MSFD Annex III.

– Number of drowned mammals and waterbirds in fishing gear – Inputs of nitrogen and phosphorous to the sub-basins, and – Oil-spills affecting the marine environment.

• Agreed targets exist for the latter two indicators

The environmental target of the pressure core indicator ’Oil-spills affecting the marine environment’ is based on a modern baseline of estimated volume of

• il-spills during the reference period 2008-

2013 (red rectangle) during which the volumes were found to be low in a historical perspective. Total input of phosphorous from 1995-2012 divided into different sources, with trendline (green) and the MAI target (red line). Similar figures are available for the respective sub-basin.

Ways to identify pressures to focus on

Identify pressures that:

• have a strong influence according to the

cumulative impact index BSPII

• are of high public interest
• are considered as emerging pressures
• can be represented by data on both spatial and

temporal information

• are reflected in the core pressure indicators.
