3: Biodiversity Change and Depth

Relating Marine Biodiversity Change to Depth in the North Sea

Combine vector and raster data to investigate environmental drivers of biodiversity change. Extract bathymetric values at biodiversity sampling points and explore relationships between depth and species turnover across the North Sea.

What You’ll Learn

  • Using emdn_get_features() to access spatiotemporal diversity metrics from EMODnet Biology (WFS)
  • Using emdn_get_coverage() to retrieve raster bathymetry from EMODnet Bathymetry (WCS)
  • Performing spatial joins and point-based extraction from raster datasets
  • Visualising and summarising patterns of species gain/loss across depth gradients

Data Sources

WFS (vector): - Layer ID: all_diversity_measures - Source: EMODnet Biology - Key variables: Species loss, species gain, β-diversity, time periods

WCS (raster): - Layer ID: emodnet__mean_2020 - Source: EMODnet Bathymetry - Description: Mean depth (m), regularly gridded

Study Area

North Sea

Bounding box (WGS84): xmin = 1.5, ymin = 53, xmax = 6.5, ymax = 58
