Instrument Development

The AOML/PHOD Instrumentation Development Group (APIDG) uses state-of-the-art technology and incorporates innovative design techniques for developing new oceanographic instruments. APIDG develops low and high-level software products for controlling high-speed data acquisition systems, embedded micro-controller applications and oceanographic instruments. These instruments and software products aid AOML in its mission to conduct basic and applied research in oceanography, tropical meteorology, atmospheric and oceanic chemistry, and acoustics.

Adaptable Bottom Instrument Information Shuttle System (ABIISS)

A deep ocean data retrieval system, once fully operational will allow scientific instruments anchored on the ocean bottom to send their data back via expendable data pods that will release from the ocean floor on a programmable schedule. Go

Autolauncher

A device for automatically launching XBT probes from a moving ship as it steams along its course. The device can be preloaded with up to eight probes and then deployed at predetermined launch times or positions. Go

Dropsonde Float

A free falling instrument that records the temperature, conductivity, pressure and average current velocity in a vertical column of water. The distance between the drop point and the point were the instruments first surfaces, represents the total vertically accumulated drift during the period of descent and ascent. Go

For more details on the applications of this instrument visit the Western Boundary Time Series (WBTS) project website.

Shallow Water Surface Drifters

A drift buoy capable of operating in water depths of one meter or less. To derive high-resolution currents, the position of the buoy is determined using a GPS receiver that stores 3 dimensional position information at pre-selected rates. Go

Future plans

Additional test cruises are planned for 2010 in which further improvement of the data pod release system and deployment techniques will be evaluated. Additional tests are also planned for testing infra-red transmission and dual-tone multiple frequency as a backup to the radio-frequency transmission between the data controller and data pods.
