The book contains the abstracts for presentations from the Annual International Conference “GeoHab 2019 – Marine Geological and Biological Habitat Mapping” (May 13–17, 2019, St. Petersburg, Russia). The presentations are devoted to study and mapping of different types of habitats – from coastal and shallow water to shelf, deep-sea and coral habitats, geological and biological features of seeps and hydrate, interactions between oceanographic processes and habitats, mapping, planning, and impact assessment for ocean energy, sustainable development of marine minerals’ extraction, submerged landscapes and archeology.
