Submarine geomorphology is the investigation of the form, processes and evolution of submarine landscapes. This field of research has strong basic and applied value. The seafloor is a vast reservoir of renewable and non-renewable resources, which include marine ecosystems, fisheries, hydrocarbons, freshwater, aggregates, deep sea minerals and blue energy, among others. Sound knowledge of seafloor geomorphology is key to maritime spatial planning, the designation of marine protected areas, the construction and operation of offshore infrastructure, and the implementation of environmental monitoring programmes. Seafloor processes constitute a geohazard to key offshore infrastructure and coastal communities. Technological progress has resulted in an explosion of knowledge that has radically transformed our view of the ocean and our planet in general. Nevertheless, the submarine realm still presents an important research frontier. The aim of this book is to present the state-of-the-art in the standard data and methods used in submarine geomorphology, to introduce the most significant submarine landforms and the processes that form them, and to highlight the applied value of submarine geomorphology to industry and ocean governance based on selected examples. This book is written for anybody with an interest in submarine geomorphology, although it is primarily aimed for undergraduate and graduate students, and professionals with limited training in submarine geomorphology.
