Geologists Seamounts

Coordinates: 18°40′N 157°40′W / 18.667°N 157.667°W / 18.667; -157.667 Geologists Seamounts (alternatively named South West Hawaii Group[1]) are seamounts in the Pacific Ocean, 100 miles (160 km) south of Honolulu, Hawaii[2] and 100–200 kilometres (62–124 mi)[3] southwest from Big Island.[4] Clockwise from north they are named Perret, Jaggar, McCall, Pensacola, Daly, Swordfish, Cross, Washington and Ellis.[5] The seamounts developed during the Cretaceous,[6] about 80 million years ago, and there is no geological relationship to the neighbouring Hawaiian Islands[3] although there may be one to the Musicians Seamounts.[7] Rocks dredged from the seamounts include iron-manganese crusts, carbonates and basalts. Corals and sponges have been recorded.[8]
