Gravity processed data (NIPRORI Gravity Meter working area dataset) of RV HAKUHO MARU during cruise KH-01-3, gridded free-air gravity anomaly

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 gravity measurement was done using a NIPR-ORI type shipboard gravitymeter.
