Description:
The summer party of the 35th Japanese Antarctic Research Expedition carried out an observa-
tion for the vertical profile of temperature and salinity in the vicinity of the sea level station at
Syowa Station, Antarctica, by using a Nansen water sampling bottle and a reversing thermometer
on January 26, 1994. We estimate the effect of seasonal density changes of the sea water above the
pressure gauge upon sea level measurement with the gauge, by comparing the density profile
determined by the observation in summer of 1994 and previous ones in winter of 1982. In possibly
typical cases, the sea level measured with the pressure gauge at Syowa Station can be about 4cm
higher in winter than in summer due to the seasonal density changes, which is about 15% of the
amplitude of seasonal sea level variation.
