Opis

Ocean margins are the transitional zones between the oceans and continents. They represent dynamic systems in which numerous processes shape the environment and result in impacting the utilization and hazard potentials for humans. These processes are influenced by a variety of steering mechanisms, from mountain building and climate on the land to tectonics and sea-level fluctuations in ocean margins. This book examines various aspects of regulation for the long-term development of ocean margins, of the impact of fluids and of the dynamics of benthic life at and below the seafloor in ocean margin systems.

From the reviews:

Praise for G. Wefer's Ocean Margin Systems

American Meteorological Society"This book examines various aspects of regulation for the long-term development of ocean margins, of the impact of fluids, and of the dynamics of benthic life at and below the seafloor in ocean margin systems."

"This book is the proceedings from the Hanse Conference on Ocean Margin Systems, which aimed to provide a forum for experts from different fields ... . what sets this book apart from other conference proceedings is the summary papers at the end of each of the four sections. These synthesise the relevant discussion session of the conference, providing interesting overviews of the different sections ... . There is something here for many people involved in continental margin research." (Trevor Tolhurst, Journal of Experimental Marine Biology and Ecology, Vol. 292, 2003)
