Winter Measurements of Sea Currents in McMurdo Sound

Abstract

Hydrological data obtained during the 1959 winter near Scott Base, Ross Island, Antarctica, are presented. Current measurements were made during the period April to August 1959; electric potentials generated by sea currents were recorded continuously during May and June, and through to August with some interruptions; temperature and salinity sampling was carried out monthly; and the Scott Base recording tide-gauge was in operation. The results showed that superimposed on the tidal currents there was a residual current transporting very dense water eastwards past Cape Armitage.
