Determining the relative impacts of multiple human stressors in coastal waters in the North Sea – Baltic Sea transition zone

28 May 2020

Outcomes:  Authors were able to map the potential cumulative impacts of multiple anthropogenic activities and their related stressors on the coastal and estuarine ecosystems in Danish waters of the North Sea – Baltic Sea transition zone.  Following this, authors analysed the differences in stressor contributions between offshore and inshore waters, and the relative local importance of stressors along a gradient from inner fjords to offshore waters.  It was determined that the five most significant stressors are nutrient introduction, climate anomalies, the introduction of non-indigenous species, noise and contaminant pollution.

How EMODnet Seabed Habitats helped the user: Provided publicly available seabed habitat data for the study area.

When was it used2020

What product was used: EU SeaMap 2016

How was the product used:  The study was based primarily on publicly available datasets for anthropogenic stressors and ecosystem components, of which EUSeaMap provided data on the seabed habitats in the study area.  Habitat data was re-classified into eight broad-scale benthic habitat types for use in this study, and merged with a manually generated spatial dataset comprising Danish fjords and estuaries.  The spatial distribution of ecosystem components and mapped stressors were summarised by calculating an ecosystem index and an unweighted stressor index.
