3-D mapping of sea ice draft with an autonomous underwater vehicle
We set out to achieve floe-scale 3-D mapping of sea ice draft and bio-optical parameters using a Multibeam SONAR and Hyperspectral radiometer mounted to an Autonomous Underwater Vehicle (AUV). The AUV utilised was the 'JAGUAR' Seabed-class vehicle from the Deep Submergence Laboratory at the WoodsHole Oceanographic Institution.
The AUV comes with a CTD and ADCP. However these are not deployed as scientific sensors and therefore are unsupported in terms of metadata. In particular the CTD was not calibrated before or during the voyage.
The AUV used a LongBaseLine system formed by three transponders to navigate to and from the survey grid. Two were located on the ice and the third was deployed from the back of the ship with an acoustic communications modem. Once at the survey grid beneath the sea ice, the AUV used the DVL to navigate using bottom-tracking of the underside of the sea ice.
We conducted 4 missions beneath sea-ice during the SIPEX-II voyage.
The current status of the data is that is in un-processed and unavailable until final processing is completed in 2013.
Persons interested in the data should contact Dr Guy Williams directly for further information and preliminary figures relating to the AUV missions.
The files currently in the archive are in raw form. Some preliminary data is provided for stations 2, 3, 4 and 6 as:
floe-2-20120926.mat
floe-3-20121003.mat
floe-4-20121006.mat
floe-6-20121013.mat
These can be accessed using the Seabed_plot routines (MATLAB) in this folder.
There is a readme file provided called what-is-this.txt
Also included is the video footage taken from the AUV using a GoPro HD Hero.

Resource lineage
- Statement
- The multibeam data from Station 20120926 was affected by incorrect deployment settings that reduced the available swath and overall integrity of the final map out and along a single transect of the grid. Ultimately there will be single MATLAB files associated with each of the stations. i.e. 20120926.mat These will contain raw and processed data for a) Engineering b) Navigation (AUV and GRID coordinate systems) c) Coordinate system information d) Multibeam e) Hyperspectral f) CTD g) ADCP
