Abstract:
Multibeam bathymetry and track line geophysical data (magnetics and gravity) were collected in the AAD (Australian-Antarctic Discordance) area by R/V Hakuho-maru KH-01-3 cruise Leg 3 in 2002.The focused survey area ranges from 123.5°E to 125.5°E and from 50°S and 48°S, along the Southeast Indian Ridge. The multibeam bathymetry was also obtained in the adjacent areas.The bathymetry was collected by SeaBeam2120 (20kHz). The bathymetry data quality is not so high due to the bad sea condition. The total magnetic field was measured using a proton precession magnetometer towed behind the ship. The gravity measurement was done using a NIPR-ORI type shipboard gravitymeter. The main objective of the survey is to reveal the extent of the oceanic core complexes and to reconstruct the mid-ocean ridge process under the melt-poor environment.
