Multiple stressors in the marine environment

In scientific studies, the focus is often on how individual stressors affect specific model organisms. However, in the marine environment, organisms are often exposed to a variety of stresses from different human activities - for example, shipping, fishing, sediment extraction or tourism - as well as natural variations in environmental conditions and climate change. Sensitivities to stressors associated with these pressures, such as temperature increases, pollutant concentrations or noise, are often species-specific.

If multiple stressors occur, a stress situation can arise that cannot be explained by the occurrence of the individual stressors alone. The temporal occurrence, the intensity and the spatial pattern of the stressors play an important role.

Change in science - interaction effects

These cumulative effects can play an important role in the state of the environment. Their assessment is required by various directives such as the Marine Strategy Framework Directive. In addition, all effects relevant to the marine environment must be taken into account, for example, when developing management strategies, implementing measures and developing marine spatial plans.

In recent years, scientists have therefore increasingly studied interaction effects between different stressors and developed concepts to assess these cumulative effects.

Contribution CREATE

In the CREATE project, this knowledge is processed and brought together with practical knowledge and the experiences of stakeholders in a transdisciplinary process. On this basis, knowledge gaps are identified, proposals for adjustments to monitoring are developed and strategies for taking these cumulative effects into account are elaborated. Where possible, knowledge gaps will be closed by the project and new concepts developed. In a transformative process, an intervention strategy for reducing the cumulative burden of multiple stressors will be developed together with all relevant actors in the study areas.

The project CREATE (Concepts for Reducing the Effects of Anthropogenic pressures and uses on marine Ecosystems and on Biodiversity) is part of the mission sustainMare within the German Alliance for Marine Research (DAM). CREATE is funded by the Federal Ministry of Education and Research (BMBF, 03F0836A).
