Description
17 compiled benthic datasets sample ecosystems over gradients of commercial bottom trawling intensity, eutrophication, oxygen depletion, and pollution. The compilation includes 18 calculated benthic indicators, such as community biomass, diversity indices, and biotic indices like AMBI and TDI. Data originates from multiple studies in the Baltic Sea, Atlantic Ocean, and Mediterranean Sea, compiled by P. Daniël van Denderen of the Technical University of Denmark.
Use Cases
Modeling the relationship between trawling intensity and benthic community metrics based on the 14 bottom trawling gradient datasets.
Comparing the performance of different biotic indices (e.g., AMBI, BENTIX, DKI) for assessing ecological status across various pressure types.
Analyzing species-level responses to environmental stressors using the combined data tables with gradient, station, and species information.
Strengths
Compiles 17 distinct benthic datasets, providing a multi-gradient perspective on anthropogenic pressures.
Calculates 18 different benthic indicators per sampling station, enabling multi-metric analysis.
Includes data from three major European marine regions: the Baltic Sea, Atlantic Ocean, and Mediterranean Sea.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment for specific modeling tasks.
The compilation is heavily skewed towards bottom trawling pressure (14 of 17 gradients), with only one gradient each for eutrophication, oxygen depletion, and pollution.
