Real-Time Vertical Temperature, and Velocity Profiles from a Wave Glider
Abstract
The long-term goal of this effort is to develop a system capable of active navigation/station keeping and able to measure profiles of temperature, conductivity and pressure in the upper part of the water column with an endurance of at least three months. The first objective of this project is to demonstrate that a wave glider fitted with an underwater winch can operate for at least two months without service and collect TD profiles in the upper 100 m of the water column. The second objective is to develop an electronic control system that will operate the winch according to pre-set environmental conditions and will download and transmit the TD data through Iridium. The first phase of the project was the procurement of a wave glider with an ADCP and the design and procurement of the underwater winch system. A first set of tests was then designed to demonstrate the navigation and station keeping capabilities of the wave glider with the addition of the winch system. The second set of tests was designed to demonstrate the winch operation at sea with a mock-up TD probe. The third set of tests was designed to demonstrate the operation of the full system with an operational TD probe in controlled conditions off the SIO pier, to test also the data link between the dry payload developed by SIO to control the winch and communicate with the TD. The final test will be the navigation of the fully working system along the coast of California.
