Instrumentation and Metrology in Oceanography
Publication Date: September 2012 Hardback 416 pp.
After a definition of measured quantities and quantities inferred from calculations, this book details the functioning of sensors and instruments used to assess the useful parameters in oceanography: temperature, conductivity, pressure, sound velocity, current in magnitude and direction, time and position with global positioning systems, height of water and tide, waves, as well as optical and chemical properties like turbidity, dissolved gas (O2, CO2), pH, nutrients and other dissolved elements. It also describes the different means used to produce measurements at sea (boats, drifting floats, moorings, undersea platforms, gliders, etc.) and techniques under development. The theoretical functioning of each sensor or instrument, as well as different practical aspects of its use, are also discussed.
1. What We Measure and What We Process.
2. Measurement Systems in Practice.
3. Measurements at Sea.
4. Evolutions and other Measurement Concepts.
