Abstract :
This paper describes new measurements made in 2011-2012 of the dielectric constant of seawater at 1.413 GHz using a resonant cavity technique. These measurements are more accurate than previous measurements made in 2008. The paper discusses the improved experimental methods used for the 2011-12 measurements. The new measurement data is also be compared with Klein-Swift (KS) model function and Meissner-Wentz (MW) model function.
