Instrumentation and Metrology in Oceanography [Hardcover]

Through research, physical oceanography aims?to solve?the numerous problems stated by thermal, optical and dynamical properties of the oceans. Instrumentation and Metrology in Physical Oceanography?describes the means used in oceanography to determine physical properties of the oceans?by medium of?in situ measurements.? This book explores the theoretical functioning?of sensors and instruments, as well as different practical?aspects of using?these tools.?The content of this book appeals directly?to technicians or engineers wishing to enhance their knowledge of instrumentation?and application?to environment surveillance.

Instrumentation and Metrology in Physical Oceanography?details the functioning of sensors and instruments used to assess the following parameters in oceanography: temperature, conductivity, pressure, sound velocity, current in magnitude and direction, time and position with GPS, height of water and tide, waves, optical and chemical properties (turbidity), dissolved gas (O₂, CO₂), pH, nutrients and other dissolved elements.?Furthermore, this book also elaborates?on the?different means used to?obtain measurements at sea (boats, drifting floats, moorings, undersea platforms, gliders&) and techniques currently being developed.
