Cape Johnson Guyot is also known as Cape Johnson Seamount or Cape Johnson Tablemount.[2] The guyot was named by Harry Hammond Hess, after his ship the USS Cape Johnson; Hess had also named the kind of flat-topped seamount "guyot" and another seamount was named after Hess himself.[3] The seamount was first described in a 1946 publication.[4] Both Hess and Cape Johnson were discovered during the same cruise[5] and Cape Johnson Guyot is the type locality of guyots.[6]
Geography and geologyedit
The seamount lies in the Mid-Pacific Mountains[7] on their southern side and is a submarine mountain with a flat top that rises[8] over 3,000 metres (10,000 ft)[9] to a depth of 1,692 metres (5,551 ft)[10][11]-1,778 metres (5,833 ft).[12] The flat top has an oval shape and a surface area of 6 by 12 nautical miles (11 km × 22 km; 6.9 mi × 13.8 mi);[13] it is characterized by a limestone dome on the summit, buried beneath sediments; in turn a volcanic hill is buried within the limestone dome.[14] The top of the seamount has a hummocky appearance which has been interpreted as a sediment cover[15] and its southeastern sector has a bank-like shape that resembles that of an atoll.[16] Cape Johnson Guyot is considered to be of Middle Cretaceous age[17] with an age of 120 million years reported[18] and shallow-water fossils were emplaced on it at that time.[19]
