Produktbeschreibung

The conservation of marine benthic biodiversity is a recognised goal of a number of national and international programs such as the United Nations Convention on Biodiversity (CBD). In order to attain this goal, information is needed about the distribution of life in the ocean so that spatial conservation measures such as marine protected areas (MPAs) can be designed to maximise protection within boundaries of acceptable dimensions. Ideally, a map would be produced that showed the distribution of benthic biodiversity to enable the efficient design of MPAs. The dilemma is that such maps do not exist for most areas and it is not possible at present to predict the spatial distribution of all marine life using the sparse biological information currently available. Knowledge of the geomorphology and biogeography of the seafloor has improved markedly over the past 10 years. Using multibeam sonar, the benthic ecology of submarine features such as fjords, sand banks, coral reefs, seamounts, canyons, mud volcanoes and spreading ridges has been revealed in unprecedented detail. This book provides a synthesis of seabed geomorphology and benthic habitats based on the most recent, up-to-date information. Introductory chapters explain the drivers that underpin the need for benthic habitat maps, including threats to ocean health, the habitat mapping approach based on principles of biogeography and benthic ecology and seabed (geomorphic) classification schemes. Case studies from around the world are then presented. They represent a range of seabed features where detailed bathymetric maps have been combined with seabed video and sampling to yield an integrated picture of the benthic communities that are associated with different types of benthic habitat. The final chapter examines critical knowledge gaps and future directions for benthic habitat mapping research. - Reviews and compares the different methodologies currently being used - Includes global case studies - Provides geological expertise into what has traditionally been a biological discipline

Autorenporträt

I joined GRID-Arendal as Managing Director in 2014. I am a native of the USA, citizen of Australia and resident of Norway; I describe myself as a "professional foreigner?. I am a graduate of the University of Washington (Seattle USA), completed a PhD at the University of Wales (Swansea UK), married an Australian and have 3 children.
I have worked in the field of marine geology and science management for over 30 years and published over 100 scientific papers. I taught marine geology at the University of Sydney and conducted research on UK estuaries, the Great Barrier Reef, the Fly River Delta (Papua New Guinea) and Antarctica. I worked for 20 years for Australia's national geoscience agency as a scientist and manager. In 2009 I was appointed a member of the group of experts for the United Nations World Ocean Assessment. Apart from managing all of GRID-Arendal's amazing activities, my interests include new methods for the conduct of environmental assessments (the expert elicitat

ion method) and the use of multivariate statistics and geomorphology to provide tools to manage the global ocean environment. I also enjoy sailing and playing the bagpipes.
