    New chemical measurement techniques are continually being developed to improve detection limits, accuracy, reliability, and to obtain data in situ or in real time. Recent work has been done in the development and application of fiber optics and fiber optic sensors (FOS) for the measurement of specific chemical parameters in saltwater systems. To date, FOS have shown great promise and seem destined to become an important contribution to our ability to predict water quality trends in marine and estuarine waters. The National Oceanic and Atmospheric Administration (NOAA) is supporting the development of FOS for measuring pH, carbon dioxide, and dissolved oxygen in marine waters. These and other FOS will be discussed with emphasis on sensor design, current research, ocean applications, and future direction.
