previously unknown volcano on the sea bottom off the

andsampled the ocean floor and collected video and data that indicate a major
volcano exists on the Antarctic continental shelf.
Eugene Domack, the expedition's chief scientist, said the volcano stands
700 meters (2300 feet) above the seafloor and extends to within roughly
275 meters (900 feet) of the ocean surface in an area known as Antarctic
Sound, at the northernmost tip of
He noted that there has been "no previous scientific record of active
volcanoes in the region. The volcano is unusual, Domack said, in that it
exists on the continental shelf, in the vicinity of a deep trough carved out
by glaciers passing across the seafloor.
In addition to mapping, the research team used a bottom-scanning video
recorder, rock dredges, and temperature probes to survey the sides and
crest of the submarine peak. The video survey revealed a surface that is
heavily colonized by bottom-dwelling organisms.
But a dark mat of underwater life broken along the edges of the volcano
by barren patches of dark, black rock indicate that lava has recently flowed
