Abyssal Channels in the Atlantic Ocean Water Structure and Flows

About this book

This book is dedicated to the study of structure and transport of deep and bottom waters through underwater channels of the Atlantic Ocean. The study is based on recent observations, analysis of historical data, and literature review.
