Wōdejebato is an undersea volcanic mountain with a flat top (a guyot),
and probably a shield volcano, in the northern Marshall Islands of the
Pacific. Formed of basaltic rocks, it is connected through a
74-kilometre (46 mi) submarine ridge to the smaller Bikini Atoll to its
southeast. Named for a sea god of Bikini, Wōdejebato rises 4,420 metres
(14,500 ft) above the ocean floor, to within 1,335 metres (4,380 ft)
of the surface. It was probably formed by a hotspot in present-day
French Polynesia before being shifted by plate tectonics. A volcanic
episode in the Late Cretaceous led to the formation of an island and a
carbonate platform that disappeared below the sea. A second volcanic
episode between 85 and 78.4 million years ago created an island that was
eventually eroded, generating an atoll or atoll-like structure that
covered the former island with carbonates. The second carbonate platform
drowned about 68 million years ago.
