The Atlantis Massif is a prominent undersea massif in the North Atlantic Ocean. It is a dome-shaped region approximately 10 miles (16 km) across and rising about 14,000 feet (4,267 m) from the sea floor. It is located at approximately 30°8′N latitude 42°8′W longitude; just east of the intersection of the Mid-Atlantic Ridge with the Atlantis Transform Fault. The highest point of the massif is around 700 metres (2,297 ft) beneath the surface.[1]
Description
It is believed that the massif was formed underneath the nearby Mid-Atlantic Ridge but was pulled from under the ridge during the movement of the
An expedition to the area in 1996 made an important advance in the study of the ocean floor. It found that a steeply sloping
Another expedition in 2016, the IODP 357 expedition, targeted this massif, drilling cores.[2]
