AXCTDAirborne eXpendable Conductivity,Temperature, and Depth probe
Manufacturer : 14 / Category : 57The AXBT / AXCTD system allows profiles of oceanographic conditions to be collected from aircraft. Deployed probe assemblies descend via parachute to the sea surface.
A float inflates on contact with water and after a short delay, a standard XBT or XCTD probe drops from the floating buoy. Data is transmitted from the probe to the buoy on a copper wire and from the buoy to the aircraft through a radio signal.
An antenna, receiver, data acquisition unit, and optional personal computer on the aircraft complete the AXCTD system and allow recording and display of the transmitted profile data.
