Tools for Oceanography and Ecosystemic Modeling

• Gebundenes Buch

Produktbeschreibung

Studying the Ocean Planet requires measuring and sampling instruments to feed models that take into account its complexity. This book presents the diversity of observation and monitoring techniques at various scales, but also different kinds of model that take into account some conceptual schemes incorporating various scientific knowledge. Sampling is approached via the efficiency of fishing gears; underwater acoustics is used to detect, count, identify and listen to live and mobile living resources. Bio-logging allows us to rely on the behavior of marine animals to help investigate environments that are difficult to sample by conventional means, while listing the physiological changes they undergo. Modeling is presented not only in a functional framework, but also in an exploratory design incorporating various scenarios for ecosystem changes under the pressure of global change. This ninth volume completes the "Seas and Oceans" Set that adopts a transversal approach leading to the governance and sustainable management of the marine environment.

Autorenporträt

André Monaco is Emeritus Director of Research for the French national center (CNRS). His research interests concern marine sedimentology and geochemistry. He was responsible for several French and European programs and has been guest editor for four special issues in international journals. Patrick Prouzet is Director of Research focusing on the ecosystem approach of Ifremer in France. He specializes in the biology and dynamics of anadromous fish such as Atlantic salmon and eels. He is the author and co-author of several works on these species or on estuary fishing.
