... Abstract This paper describes a study conducted to develop new capabilities for offshore geomagnetic surveying. To conduct the research we equipped two (2) new generation autonomous marine vehicles (AMVs) with towed marine magnetometers. This paper describes the validation study...

... Abstract A Slocum-class underwater glider has been modified for autonomous mapping of the underside of icebergs. A scanning sonar has been integrated inside the extended nose-section of the vehicle. The sonar is oriented to scan a sector to forward-side of the vehicle. A control algorithm using...

... to operate unsupervised is the high Arctic field work by two Arctic Explorer Autonomous Underwater Vehicles (AUVs) built by ISE for Natural Resources Canada (NRCan). They were deployed in 2010 and 2011 to conduct under-ice bathymetric surveys in support of Canada's sovereignty claim under the United Nations...

... Abstract The introduction of autonomous underwater vehicle (AUV) technology in the Oil and Gas arena has and continues to demonstrate significant advantages in offshore underwater operations. In the arctic regions, it is difficult to conduct "Life of Field" inspection operations from a support...

... Abstract This paper describes a study using an autonomous marine vehicle with satellite communications, to accurately collect and deliver in real-time magnetic measurements, to calculate Total Magnetic Intensity in marine environments in the absence of Earth magnetic observatories. New...

This approach enables the CAAT...

... Abstract The paper provides information on a unique vehicle, the amphibiousHoverbarge which can be used for transporting heavy cargo, modules and drillingrigs over Arctic terrain, such as snow, ice and tundra. The paper draws uponexperience of Hoverbarge operations in Alaska back in the 1970s...

... Abstract We describe a new underwater vehicle for under-ice telepresence, NereidUI ( Under Ice ). This paper discusses potential applications, environmental and logistical constraints, and progress to date. Based on lightdata-only fiber tether technology, Nereid UI will provide...

... Abstract Under-ice exploration in the Arctic Ocean requires robust and reliable robotic tools. Autonomous underwater vehicles (AUVs) used in this environment have to be able to navigate reliably and with precision without the help of a dedicated infrastructure. They also have to be able...

... Abstract We describe our work undertaken to analyse sea ice pressure ridge morphology in the Arctic ocean from Autonomous Underwater Vehicles (AUVs) and submarines. Details of cruises, from ship-based launches of large (7m) AUVs to hand deployed AUVs are given, as well as the first submarine...
