RRS Discovery D343
Cruise summary report
|Ship name (ship code)||RRS Discovery (74E3)|
|Cruise period||2009-09-27 — 2009-10-15|
|Port of departure||Govan, United Kingdom|
|Port of return||Govan, United Kingdom|
|Objectives||Testing of theAutosub6000 AUV, its systems and safe control to as deep as possible up to 6000 m
Testing of collision avoidance system based on scanned sonar collision avoidance sensor
Testing of: Dual CT, LSS (Light scattering sensor), EH probe and magnetometer and Mulitbeam sonar
Participation of two researchers from University of Birmingham who are developing a fault diagnosis system for Autosub6000
Test of the HYBIS system in as deep water as possible (NOCS, Southampton).
Testing of Acoustic and Satellite Telemetry systems (POL, Liverpool).
To develop and test remote measurement technologies, deep water communication systems and a compact version of the MYRTLE (multi-year return tide level equipment) long term deep water recoverable lander.
The cruise began with initial tests of the Autosub6000 AUV in the Celtic deep, followed by deep tests of the AUV to 5600m on the Iberian Abyssal plain. HYBIS also carried out a successful deep test in this location. The majority of the work for the Autosub6000, HYBIS and the POL telemetry tests were carried out further south over and around the Casablanca seamount. A high percentage of the tests were successful.
