/* DATA DESCRIPTION: Citation: Okino, Kyoko (2023): Magnetic processed data (Proton precession magnetometer working area dataset) of RV HAKUHO MARU during cruise KH-01-3, gridded magnetic anomaly [dataset]. PANGAEA, https://doi.org/10.1594/PANGAEA.962016, In: Okino, K (2023): Australian-Antarctic Discordance: bathymetry, magnetics, gravity [dataset bundled publication]. PANGAEA, https://doi.org/10.1594/PANGAEA.962015 Abstract: 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 total magnetic field was measured using a proton precession magnetometer towed behind the ship.
