This book contains the results of a 9 year (1995-2004) investigation of the Canary Islands Exclusive Economic Zone, using state of the art technology. The coverage includes a multibeam survey demonstrating the magnitude of catastrophic failures of the Canary Islands; a comparison of the morphology of the Canary Islands with Hawaii; evaluation of hydrothermal activity associated with Mesozoic salt diapirs; and many more articles.
Juan Acosta is the main researcher for the project of which the results are presented in this book.
Peter Clift has done his research and teaching at MIT, WHOI, and is currently affiliated with the University of Aberdeen. He has served and is currently Editor for several journals, amongst others Marine Geophysical Researches.
This book contains the results of a 9 year (1995-2004) investigation of the Canary Islands Exclusive Economic Zone, using state of the art technology. The main result areas are:A multibeam survey demonstrating the magnitude of catastrophic failures of the Canary IslandsA comparison of the morphology of the Canary Islands with HawaiiThe significance of hydrothermal activity in the Canary Channel associated with Mesozoic salt diapirsAn analysis of the morphology and structure of the offshore extension of the Anaga massif in Tenerife islandA detailed description of the archipelago gravity field and magnetic field of the Canary IslandsAll in all the wealth of new data and ideas presented in this collection of papers has rarely been equaled in an investigation of an oceanic island group.
