Abyssal plain is an extensive, flat, gently sloping or nearly level region at abyssal depths. Three abyssal plains were mapped where their gradients became generally flat and at depths greater than about 4000 m. In the north are the abyssal plains of the Coral Sea Basin and Louisiade Basin, the latter being a failed arm of a rift triple junction. In the south, lies the abyssal plain of the Tasman Basin.
