Activities of Japanese geochemistry party in the Dry Valleys region during the 1984-1985 field season

Abstract

In the 1984-1985 summer season, science activities of Japanese geochemistry party are divided into two categories. The first one is the participation in the Cenozoic Investigations of the Western Ross Sea (CIROS) Project and the second one is the geochemical and environmental studies of the Dry Valleys region including the area near Scott Base in Ross Island. Water samples, ground surface detritus and algae were collected in this region from a limnological and environmental point of view. The sampling was made mostly in the North Fork and South Fork and the Labyrinth area in the Wright Valley. A NaI (Tl) scintillation survey meter was used to measure the environmental radiation level and a preliminary use of TLD (thermoluminescence dosimeter) was also made for monitoring the integral radiation dose. Concentrations of cosmic-ray induced ^8 and natural ^Pb in surface air were measured for air dust samples collected at Scott Base and CIROS-2 drill site.
