The History of Standard Seawater for Salinity Measurements
摘要
The history of Standard Seawater, from its beginnings in 1899 by Martin Knudsen, through to its current preparation at Ocean Scientific International Ltd (OSIL), is described in this chapter. Having been used for over 120 years as a reference material in the determination of salinity, how the standard was developed and maintained to allow for continuity is discussed.
