Control Capabilities of Jason and its Manipulatorshion. Coordinated control can greatly increase the workspace of the manipulator without the need for additional or larger manipulator links. Such control will also minimize the need for attachment points, which is especially important in unprepared or poorly structured environments..This paper revi

Sea Bed Sampling with an Expendable Acoustic Penetrometer Systements to a depth of approximately 9 m in water depths to 6 km. Doppler frequency shifts associated with changing velocities during bottom penetration are measured relative to a highly stable sound source which is attached to a slender weighted body. The varying rates of deceleration are correlated by

A Site-Specific Sampling System for EEZ Hard Mineral Depositsin use. In response to this need, a tethered, multiple coring system for the recovery of site-specific samples of manganese crust has been designed, fabricated, and tested at sea. This system consists of an array of thirty core guns, bottom triggering and sequencing electronics, an acoustic telemetr
