The group velocity of light has been measured at eight different wavelengths
between 385 nm and 532 nm in the Mediterranean Sea at a depth of about 2.2 km
with the ANTARES optical beacon systems. A parametrisation of the dependence of
the refractive index on wavelength based on the salinity, pressure and
temperature of the sea water at the ANTARES site is in good agreement with
these measurements.
