In August of 2010 Polar-ARV participated in the 4th Chinese National Arctic Expedition(CHINARE)for the second time. It accomplished the observation of 17 horizontal sections under sea ice at latitude of about 87 degrees north. During Polar-ARV working under the sea ice, the seawater temperature, salinity, pressure, sea ice thickness and ice optical properties, as well as the video of sea ice were...
In March and April 2010, an ISE Explorer Autonomous Underwater Vehicle (AUV), built for Natural Resources Canada (NRCan), was deployed to Canada's high Arctic. Its mission was to undertake under-ice bathymetric surveys in support of Canada's submission to establish the outer limits of its continental shelf under the United Nations Convention on the Law of the Sea (UNCLOS). During this deployment several...
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...
In March and April 2010, an International Submarine Engineering (ISE) Explorer Autonomous Underwater Vehicle (AUV), built for Natural Resources Canada (NRCan), was deployed to Canada's High Arctic. Its mission was to undertake under-ice bathymetric surveys in support of Canada's United Nations Convention on the Law of the Sea (UNCLOS) Outer Continental Shelf claim. During this deployment several under-ice...
Autonomous Underwater Vehicles are a leading technology for under-ice deployment and research. Memorial University and its Explorer AUV, in cooperation with the University of Tasmania and the Australian Antarctic Division, has embarked on a multi-phase development program that will lead to a scientific mission in the Australian Antarctic. Completion of Phase I saw the AUV deployed in the Canadian...
In the past few years, there has been increasing interest in the use of the Arctic, both as an ocean waterway and as a source of natural resources and food. In support of these objectives, scientific studies and research to characterise the Arctic environment are being initiated. At the same time, northern nations have begun to collect the data that is necessary to assert their sovereignty claims...
An autonomous underwater vehicle (AUV) designed for operation at high latitudes and under ice, completed its first Arctic field tests from the USCGC Healy in October 2001. The ALTEX (Atlantic Layer Tracking EXperiment) AUV's initial application was focused on tracking the warm Atlantic Layer inflow - the primary source of seawater to the Arctic Ocean. The primary payloads were twin pumped CTD systems...
We present operational experiences from two deployments of a small Gavia AUV in the high Arctic. Deployments took place from the U.S.-led APLIS camp, in the Beaufort Sea during May 2007 and from a small independent ice camp, on the fast ice just north of Canada's Ellesmere Island, in May 2008. Both deployments took place through a 3 times 1 m access hole in first-year (FY) sea ice made with hot water...
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...
The Arctic seafloor remains one of the last unexplored areas on Earth. Exploration of this unique environment using standard remotely operated oceanographic tools has been obstructed by the dense Arctic ice cover. In the summer of 2007 the Arctic Gakkel Vents Expedition (AGAVE) was conducted with the express intention of understanding aspects of the marine biology, chemistry and geology associated...
