ABSTRACT: A gravity survey on
Mizuho Plateau was carried out in austral summer of 2001-2002 by the 43rd Japanese Antarctic Research Expedition (JARE-43), as one of the geophysical measurements
of deep seismic exploration. Gravity measurements were conducted at 151 points in
approximately 1 km interval along the 150 km profile. Considering the gravity
effect from the ice-sheet, Free-air and Bouguer anomalies were calculated by
using precise GPS locations. Furrowed and basin-like negative Free-air
anomalies were observed in middle and northern parts of the profile. Bouguer
anomalies were calculated by two bedrock elevation data obtained from seismic
refraction and radio-echo sounding. High resolution model for bedrock elevation
by radio-echo sounding was applied in determining the crustal thickness.
