The deep oceans and global seafloor are truly Earth's last frontier. They remain largely unexplored, yet are critical to our survival on this planet. This magnificent, full-color volume transports you to bizarre landscapes hosting exotic life forms that rival the most imaginative science fiction. Starting with a historical summary of seafloor exploration and the developing technologies used to study this extreme environment, it then describes the distinctive geologic components of the Earth's ocean floor and the unusual biological communities found along the mid-ocean ridges. This is an indispensable reference for researchers, teachers, and students of marine science, and a visually stunning resource that will enlighten and intrigue oceanographers and enthusiasts alike. A suite of online resources, including photographs and video clips, combine with the book to provide fascinating insights into the hidden world of seafloor geology and biology using the latest deep-sea imaging and geological concepts.

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 106.Seafloor spreading at mid-ocean ridges was recognized more than 30 years ago as the key which unlocked the plate tectonic revolution. Ridges are not only the locus of the most voluminous magmatic activity on Earth, but they are also the largest and most active extensional tectonic regime on the planet. The abyssal hills of the seafloor, formed at mid-ocean ridges, are the most widespread morphologic features on the planet. Beneath these ridges, oceanic lithosphere forms nearly 60% of the volume of the Earth's rigid outer shell. As impressive as this may be, it is worth recalling that similar volumes have been created repeatedly in the cycle of spreading and subduction of oceanic tracts that characterizes plate tectonics.
