Measuring Ocean Currents: Tools, Technologies, and Data covers all major aspects of ocean current measurements in view of the implications of ocean currents on changing climate, increasing pollution levels, and offshore engineering activities. Although more than 70% of the Earth is covered by ocean, there is limited information on the countless fine- to large-scale water motions taking place within them. This book fills that information gap as the first work that summarizes the state-of-the-art methods and instruments used for surface, subsurface, and abyssal ocean current measurements.

Readers of this book will find a wealth of information on Lagrangian measurements, horizontal mapping, imaging, Eulerian measurements, and vertical profiling techniques. In addition, the book describes modern technologies for remote measurement of ocean currents and their signatures, including HF Doppler radar systems, satellite-borne sensors, ocean acoustic tomography, and more. Crucial aspects of ocean currents are described in detail as well, including dispersion of effluents discharged into the sea and transport of beneficial materials-as well as environmentally hazardous materials-from one region to another. The book highlights several important practical applications, showing how measurements relate to climate change and pollution levels, how they affect coastal and offshore engineering activities, and how they can aid in tsunami detection.

Joseph, Antony
Dr Antony Joseph has over 40 years' experience in oceanography research on various aspects related to oceanographic sciences, ocean technologies, limnology, hydrology, meteorology, and surface meteorology technologies. He is currently retired but was Chief Scientist of the National Institute of Oceanography, India for 34 years where he conducted research in the areas of ocean currents, sea-level, and surface meteorological measurements. Dr Joseph has worked in numerous countries such as the UK, Norway, Portugal, France, Ghana, Singapore, Japan, South Africa, Russia, Australia, and USA on official capacity in connection with sea-level related research and operational activities. He has authored three Elsevier books: Tsunamis: Detection, Monitoring, and Early-Warning Technologies (2011); Measuring Ocean Currents: Tools, Technologies, and Data (2013); and Investigating Seafloors and Oceans: From Mud Volcanoes to Giant Squid (2016).
