The crater floor, averaging about 505 m below the sea surface, is marked in its northeast area by a field of hydrothermal vents and covered by a thick bacterial community, the 2006 NOAA expedition discovered.
At a depth of approximately 505 m beneath the ocean's surface, the crater's northeastern region features a vast array of hydrothermal vents, which are in turn supported by a thick layer of bacteria, as highlighted by the 2006 NOAA expedition's research.
