TIDES AND TIDAL CURRENTS IN THE ANTARCTIC SEA OBSERVED AT SYOWA STATION, EAST ANTARCTICA
Tidal currents were observed at the Kita-no-seto Strait near Syowa Station for 15 days from January to February, 1982 by the 23rd Japanese Antarctic Research Expedition. The observed currents show a semidiurnal type in contrast with the tides at Syowa Station showing a mixed type. Judging from the a...
