Advances in In-Situ Ocean Measurements

This chapter focuses on recent advances in in-situ ocean measurements. Recent interest in the ocean’s response to and impact on climate change has encouraged the development of improved sensor technologies for measuring oceanic parameters such as conductivity, temperature, dissolved oxygen and pH. It introduces various sensors used for measuring oceanic parameters, the underlying principles of these sensors and their respective calibration parameters. It also discusses what is still needed in the development of sensors to achieve the oceanographic need.
