The Tasman Sea is 2,250 km (1,400 mi) wide and has an area of 2,300,000 km 2 (890,000 sq mi). [1] The maximum depth of the sea is 5,943 m (19,498 ft). [4] The base of the sea is made up of globigerina ooze. A small zone of pteropod ooze is found to the south of New Caledonia and to the southern extent of 30°S, siliceous ooze can be found. [5]
The Tasman Outflow is a water pathway connecting water from the Pacific Ocean and the Indian Ocean. The existence of the outflow was published by scientists of the Australian CSIRO 's Division of Marine and Atmospheric Research team in August 2007, interpreting salinity and temperature data captured from 1950 to 2002.

The South Tasman Rise is also known as the Tasmania Ridge or South Tasmania Ridge. The South Tasman Rise is a sunken landbridge that used to connect Tasmania to Antarctica. Exploration of this oceanic region has taken place via sonar, gravity field, magnetic field, a few drill holes and deliberate or accidental dredging of rocks up to the surface.
Sea surface temperature contrasting with the warm eddies that are found on the East Australian Current [12] Rapid formation in the sea within a preexistent trough of low pressure [ 12 ] Much rarely, in the wake of a cold front heading across from Victoria into the Tasman Sea (i.e. a cut-off low originally enclosed within the westerly wind band ...
However, when a blocking high is situated in the Tasman Sea it can cause torrential rains in eastern Australia, as in the cases of the 2021 and 2022 flood events. [14] A blocking high in the southern Tasman Sea directs low pressure systems and troughs towards eastern Australia, whereby providing rainfall on the east coast of Australia. [15]
The Puysegur Trench and Macquarie Ridge are marked by the line extending south from the southwestern South Island. The 6,300-metre (20,700 ft) deep [1] Puysegur Trench is a deep cleft in the floor of the south Tasman Sea formed by the subduction of the Indo-Australian Plate under the Pacific Plate to the south of New Zealand.
The eddies produced cause an increase in vertical mixing within the Tasman Sea. The process of producing, moving, and destroying eddies causes the thermocline layer to mix with the surface layer, bringing some nutrients up to the surface.
