A low-power, modular, telemetering microstructure system for measuring upper-ocean turbulence from autonomous vehicles
Abstract
Abstract Mixing is one of the most critical quantities to observe in order to improve our understanding of the ocean, which is chronically and critically under-observed. The objective of the proposed work is to develop a modular system for measuring both shear and temperature microstructure, as well as other quantities such as microconductivity, in an inexpensive, low-power package capable of telemetering data back to shore. The system will be easily deployable on moored profilers, gliders, wire walkers, floats and other autonomous vehicles, greatly increasing the number and ease of turbulence observations and significantly expanding our ability to 1) field extensive 3-D arrays of profiling moorings and 2) contribute to autonomous experiments such as the Flow Encountering Abrupt Topography (FLEAT) and Northern Arabian Sea Circulation autonomous research (NASCar) programs, for the study of a variety of complex ocean processes including internal waves, submesoscale flows and turbulence. Better understanding and measurement of these processes is vital for improving the fidelity of regional and climate models and better prediction of ocean state. The PIs on this proposal supervise graduate students, and it is expected that this technology will form a significant component of a number of Ph.D. projects and significantly enhance their ability to conduct meaningful research.
