Louisville Ridge
The Louisville seamount chain is an underwater chain of over 70 seamounts in the Southwest Pacific Ocean. One of the longest seamount chains on Earth, it stretches some 4,300 kilometres[1] from the Pacific-Antarctic Ridge ENE to the Tonga-Kermadec Trench, where it subducts under the Indo-Australian Plate as part of the Pacific Plate. The movement of the Pacific Plate over the Louisville hotspot formed the chain.
Depth-sounding data first revealed the existence of the seamount chain in 1972.[2]

The Louisville seamount chain was first detected in 1972 using depth soundings collected along random ship crossings of the South Pacific. Six years later the full extent of this chain was revealed by a radar altimeter aboard the Seasat (NASA) spacecraft.
