Benthic 'weather' current meter array

摘要

An array of deep ocean current meters capable of resolving Reynolds stress, deployed on 10 km grid spacing over an area 100 km x 100 km, can resolve benthic storms responsible for eroding and transporting sediment. The requirement for such anarray is that the current meters be inexpensive yet capable of obtaining stress measurements. A design for both instrument and array must include power, logging, and noise considerations; recovery of instruments and/or data; and economics and logistics of deployment. A version of the Modular Acoustic Velocity Sensor, MAVS, is to be adapted to this task.
