An acoustic technology developed at Pacific Northwest National Laboratory eliminates the need for laborious and costly sampling of slurries in large containers. Fermentation-based industries, such as ...
MIT's Van Atta Acoustic Backscatter leverages decades' old tech to create a promising new means of submersible signal transmission. By Andrew Paul Published Sep 7, 2023 5:00 PM EDT Get the Popular ...
Acoustic measurement of suspended sediments has emerged as a vital approach for quantifying the concentration and characteristics of particulate matter in aquatic environments. This method utilises ...
ABSTRACT: Acoustic backscatter contrast in depositional sediments under salmon farm cages in the Bay of Fundy, Canada, was correlated with localized changes in (unknown) sediment geotechnical ...
Challenges in approaches to creating underwater communication links. How a unique piezoelectric array can be used for zero-power links. The special electrical and mechanical issues addressed when ...
Tracking drones or whales under the ocean is very difficult because GPS signals break down rapidly in seawater. Typically tracking objects underwater is done using acoustic signaling, but tracking ...
Researchers have developed a battery-free underwater communication system that uses near-zero power to transmit sensor data. The system could be used to monitor sea temperatures to study climate ...
