Hydroacoustic Mapping of Geogenic Hard Substrates: Challenges and Review of German Approaches
Subtidal hard substrate habitats are unique habitats in the marine environment. They provide crucial ecosystem services that are socially relevant, such as water clearance or as nursery space for fishes. With increasing marine usage and changing environmental conditions, pressure on reefs is increas...
