F R O M the very inception of contemplated space flight, the Air Force has been vitally interested in research directed toward provision of a safe and habitable environment under the hostile conditions of space. The idea of safely sustaining man in a closed system for relatively long periods of time is not particularly new or unique. The Navy has been confronted with this problem for many years...

Similar submarine canyon systems exist on scales ranging from less than a kilometer to nearly 1000 km. The shallowest end is a submarine canyon and canyon head(s). Further down the canyon is buried by the upper part of a submarine fan with meandering and cross-cutting channels. The fan eventually merges with a nearly flat-lying depositional basin. We have used the deposits associated with these...

This research investigates the creation and integration of a comprehensive three-dimensional submarine undersea battlespace visualization (SUBV) with existing platform fire control systems to enhance the weapons fire control decision-making process. Using 3-D visualization to represent undersea environments, mission planners and command and control (C&C) personnel can gain a tactical advantage ...

Deep sea mining tailings disposal is a new environmental challenge related to water pollution, mineral crust waste handling, and ocean biology. The objective of this paper is to propose a new tailings disposal procedure for the deep sea mining industry. Through comparisons of the tailings disposal methods which exist in on-land mining and the coastal mining fields, a new tailings disposal proce...

Submarine landslides are an important process in volcano growth yet are rarely observed and poorly understood. We show that landslides occur frequently in association with the eruption of West Mata volcano in the NE Lau Basin. These events are identifiable in hydroacoustic data recorded between ~5 and 20 km from the volcano and may be recognized in spectrograms by the weak and strong powers at ...

IT IS WELL KNOWN that there are several submarine banks along the submerged rise which extends southwestward from the southern tip of Izu Peninsul a, centr al Honshu. Small islands such as Tosh ima, Niijima, Shikine, and Kozu, with several other islets, lie on th is rise. These, together with a few other islands situated farther south; are called the Izu Islands. They are linked by a volcanic s...
