Abstract: A communication float for an oceanographic instrument, such as a profiler, comprising an elongated buoyant float, connected at one to the instrument by means of a neutrally buoyant communication cable, and having an antenna mounted on the other end. The float is ballasted to float at an angle such that the antenna extends from the water when the float is on the surface of the water, and whereby the float is oriented substantially vertically when submerged. The communication float is configured to provide minimal effects on the profiler instrument for either the submerged or floating mode, and to maintain transmission while subjected to wave action on the ocean.

Abstract: A buoyancy package for subsurface instrumented moorings with reduced drag and increased stability is provided with the use of spherical buoyant members enclosed in a pivotally connected streamlined housing. The use of a spherical buoyant member provides a buoyant member capable of withstanding high pressures for deep water applications, and in one embodiment provides a convenient structure for providing a pivot with respect to the housing.

Abstract: A system for the automated deployment and retrieval of an oceanographic data collecting probe from a vessel in motion. The system involves ejecting the probe line rapidly from a drum such that substantially all of the line is deposited in proximity with the region of descent of the probe to reduce line drag for rapid probe descent. The system is designed for repeated deployment and retrieval of the line allowing unattended operation.
