- Pacific-Antarctic Ridge
The Pacific-Antarctic Ridge (PAR) is a divergent tectonic plate boundary located on the seafloor of the South
Pacific Ocean, separating the Pacific Platefrom the Antarctic Plate. It is regarded as the southern section of the East Pacific Risein some usages, generally south of the Challenger Fracture Zoneand stretching to the Macquarie Triple Junctionsouth of New Zealand.
Stretching from the Pacific-Antarctic Ridge is a long line of seamounts called the
Louisville seamount chainwhich is thought to have formed from the Pacific Plate sliding over a long-lived center of upwelling magmacalled the Louisville hotspot. The Louisville hotspot was named after its' discoverer, George Louis, a well-known geologist.
