Use of a REMUS-100 AUV to obtain hydrographic observations beneath coastal sea ice offshore of Barrow, Alaska is described. The work is motivated by the desire to obtain cross-shore hydrographic transects that would provide estimates of the transport of relatively dense, salty water from the Chukchi Sea to the Arctic Ocean in winter. The horizontal scales (~10 km), maximum water depths (~100 m) and...
AUVs have proved robustness and high performance in applications including naval mine counter measures, marine research and deep water offshore oil and gas surveys. A next step is to introduce AUVs to under ice geophysical surveys. A main challenge for regular under ice operations is to handle the risk of a loss of a vehicle, or long operational interruptions. The paper discusses how to reduce this...
Underwater technologies have advanced to the point where the development of autonomous underwater vehicles, or AUVs, is driven by the scientific end user rather than the AUV developer. This results from AUV platforms becoming increasingly commercially available and finding application in a wide range of fields including physical, chemical, biological and geological sciences. Scientific payloads carried...
