The Tasman Front is a relatively warm water east-flowing surface current and thermal boundary that separates the Coral Sea to the north and the Tasman Sea to the south.

Naming[edit]

The name was proposed by Denham and Crook in 1976,[1] to describe a thermal front that extends from Australia and New Zealand between the Coral Sea and Tasman Sea.[2][3]

Geography[edit]

Originating in the edge of the East Australian Current (EAC), the Tasman Front meanders eastward between longitudes 152° E and 164° E and latitudes 31° S and 37° S,[4][5] then reattaches to the coastline at New Zealand, forming the East Auckland Current.[6]

Topography plays a dominant role in establishing the Tasman Front.[2] Data on the Tasman Front shows that the path of the front is influenced in part by the forcing of the flow over the major ridge systems.[7] Meanders observed in the Tasman Front can be driven by meridional flows along ridges such as those observed at the New Caledonia Trough (166° E) and the Norfolk Ridge (167° E). Abyssal currents also drive meanders associated with the Lord Howe Rise (161° E) and Dampier Ridge (159° E).[8]

Oceanography[edit]

There have been a number of observational[5][7] and modeling[8][9] studies on this front in addition to a number of paleo-oceanographic studies of marine sediments.[10] Contrarily, there have been few biological observational studies, but those have been conducted resulted in relating the physical features of the front to properties of fish communities.[11] Likewise, there are even fewer studies relating biogeochemical properties to physical processes of the Tasman Front.[3]
