The book outlines many years of research in the abyssal channels of the Atlantic, consistently discusses various aspects of the distribution of deep and bottom waters. The properties of deep and near-bottom waters and the conditions for their formation are described. The mechanisms of formation of these waters and their circulation were analyzed. A comparison of various definitions of bottom waters in Antarctica (as well as some other water masses) and criteria for determining their boundaries is carried out. A general review is given of the ways in which bottom waters spread and a general scheme of the distribution of Antarctic waters in the depths of the Atlantic Ocean after distribution from their sources in the Southern Ocean is described. Quantitative indicators of flow rates of bottom waters in abyssal channels are given. A comparison is made of the boundaries of the distribution of Antarctic waters depending on the specific characteristics used for their identification.
This book is dedicated to the analysis of bottom waters flows through underwater channels of the Atlantic Ocean. The study is based on recent observations of the authors, analysis of historical data, numerical modeling, and literature review. For example, studying both the measurements from the World Ocean Circulation experiment in the 1990s and recent measurements reveals the decadal variations of water properties in the ocean.
Seawater is cooled at high latitudes, descends to the ocean bottom, and slowly flows to the tropical latitudes and further. This current is slow in the deep basins, but intensifies in the abyssal channels connecting the basins. The current overflows submarine topographic structures and sometimes forms deep cataracts when water descends over slopes by several hundred meters. The flow of Antarctic Bottom Water (AABW) is studied on the basis of CTD sections combined with Lowered Acoustic Doppler Profiling (LADCP) carried out annually, and long-term moored measurements of currents.
This book is a collection of oceanographic data, interpretation, and analysis, which can be used by field oceanographers, specialists in numerical modeling, and students who specialize in oceanography.
