• Building blocks — vehicles, sensors, sampling, shore systems — being created for new types of observing systems • Sensors need more investment • Physical and biological models connect in very different ways (at different levels of maturity) • Data from these systems still a struggle to manage
The autonomous localization and tracking of the center of a phytoplankton bloom patch by the Tethys Autonomous Underwater Vehicle (AUV) is introduced. This capability is motivated by the desire to separate temporal variability from spatial variability in the observation of phytoplankton dynamics. In effect, by observing the organisms in their own reference frame, we isolate their temporal variability...
A scripting language for state configured layered control of a long range autonomous underwater vehicle (AUV) is introduced. The XML-based language has been designed to meet the complex requirements for long-term autonomous operation. It does not require that mission planners be programmers, yet allows them to have a high degree of certainty at deployment that the robot will do what they want it to...
Thermoclines play a key role in ocean circulation, marine ecology, and underwater acoustics. In oceanographic surveys, it is often desirable to detect the thermocline and track its spatio-temporal variation. Mobility of an autonomous underwater vehicle (AUV) makes it an efficient platform for thermocline tracking. In this paper, we present a fully autonomous algorithm for detecting and tracking the...
The Tethys autonomous underwater vehicle (AUV) is a 110 kg vehicle designed for long-range, high- endurance operations. Performance goals include supporting a payload power draw of 8 W for a range of 1000 km at 1 m/s, and a power draw of 1 W for 4000 km at 0.5 m/s. Achieving this performance requires minimizing drag and maximizing propulsion efficiency. In this paper, we present the design of the...
This article describes the development of Odyssey IIb, which has been modelled on the Odyssey II autonomous underwater vehicle. The new vehicle is designed with a modular subsystem to permit interchange of all vehicle components within the class and to allow for a variety of missions at depths of up to 6000m. The article discusses the configuration of the fairings and housings, the tailcone propulsion...
