/* DATA DESCRIPTION: Citation: Okino, Kyoko (2023): Multibeam bathymetry processed data (SeaBeam 2120 entire dataset) of RV HAKUHO MARU during cruise KH-01-3 [dataset]. PANGAEA, https://doi.org/10.1594/PANGAEA.961502, In: Okino, K (2023): Australian-Antarctic Discordance: bathymetry, magnetics, gravity [dataset bundled publication]. PANGAEA, https://doi.org/10.1594/PANGAEA.962015 Abstract: Multibeam bathymetry 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.
