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 Islands
A comparison of the morphology of the Canary Islands with Hawaii
The significance of hydrothermal activity in the Canary Channel associated with Mesozoic salt diapirs
An analysis of the morphology and structure of the offshore extension of the Anaga massif in Tenerife island
A detailed description of the archipelago gravity field and magnetic field of the Canary Islands
All 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.
