  1. Use of PSA data forhabitat mapping Markus Diesing Marine Habitats & Mapping Team

  2. What is habitat mapping? • Plotting the distribution and extent of habitats • Output: map with complete coverage of the seabed showing distinct boundaries separating adjacent habitats

  3. What are habitats? • Place where an animal or plant lives • Place where a community lives • Physical and environmental conditions that support a particular community • Often used synonymous with biotopes

  4. How do we map habitats?

  5. How do we map habitats?
