Wōdejebato is a Cretaceous guyot or tablemount in the northern Marshall Islands, Pacific Ocean. It was probably formed by a hotspot in what is present-day French Polynesia before plate tectonics moved it to its current location. The name of the seamount comes from WōdeJebato, the most feared and respected sea god of Pikinni Atoll.
About Wōdejebato in brief
Wōdejebato is a Cretaceous guyot or tablemount in the northern Marshall Islands, Pacific Ocean. It was probably formed by a hotspot in what is present-day French Polynesia before plate tectonics moved it to its current location. The name of the seamount comes from WōdeJebato, the most feared and respected sea god of Pikinni Atoll. The seamount is 4,420 metres high above the sea floor and has an irregular shape, with spurs projecting from its circumference. It is about 43 kilometres long with a 1,200 square kilometres flat top that narrows southeastward from over 25 kilometres to less than 12 kilometres. The surface of the flat top slopes inward and is covered by small depressions and knobs with an average relief of about 1 metre as well as ripple marks. The flat top is surrounded by a ridge, which has a width of 100–800 metres and an average height of 36 metres. On its northern and northeastern side, this ridge is in turn surrounded by another 200–700 metres wide slightly raised ridge. Small mounds, probably of biological origin, are found at the margins of the seamsount. Another volcanic cone, at a depth of 3,000 metres, seems to have collapsed in the past, and there is a downdropped terrace, where there are channels and forms resembling cone-shaped cones. Wō dejebatos appears to have four ridges, which is more than observed at Hawaii.
One explanation is that the northwestern ridge is another seamount; another that consists of more than one volcano, although the relatively small size of the volcano would argue against this view. The guyot is connected through a submarine ridge to the smaller PikinnI Atoll 74 kilometres southeast of the guyot; unlike Wohdejbato, Pikinn i rises above sea level. Woh dejbatos was formerly called Sylvania, after the USS Sylvania, a ship which was involved in its first mapping in 1946. The seamsount was discovered in 1944, and was first investigated, using mainly seismic data, during Operation Crossroads ). Later, several times rocks were dredged from the seamOUNT and drill cores were taken; cores 873–877 of the Ocean Drilling Program are from Woh Dejbats. Wō Dejebats is also written as Wodejebata or Wode Jebato. It is believed to have been part of the Ralik Chain of islands and seamounts, which consist of about three northwest-trending groups of islands of volcanic origin. Pikinna Atoll ) is located about 74 kilometres southeast of WōDejebaters seamount and is formed by basaltic rocks. It has a flat top has been interpreted as a lagoon surrounded by reefs which form the inner ridge; the outer ridge appears to be a pile of skeletal sand rather than a reef.
