Seamount X

Stratovulcano · United States · 1230 m (sottomarino)

A bathymetric map showing Seamount X was produced using data from 2004 and 2006 NOAA submarine vents expeditions. The seamount lies about 70 km WSW of Guam and displays areas of hydrothermal venting. The contour interval is 200 m.

Sintesi geologica

Hydrothermal activity was detected during a 2003 NOAA expedition at a submarine volcano about 70 km WSW of Guam. The summit of the volcano, referred to as Seamount X, lies 1,230 m below the ocean surface. Diffuse sites of thermal venting colonized by shrimps, crabs, and scaleworms were detected near the summit during a 2006 NOAA expedition, and thick deposits of sulfur flows originating from the hydrothermal vent were observed that were covered with thousands of squat lobsters. Basaltic rocks were recovered along with sulfur samples. The summit of the volcano is cut by an elongated caldera.
