The next frontier of maritime networking will see the deployment large-scale buoy-based mesh networks, with an equal emphasis on both high-speed data transfer and energy-efficiency. One such challenging application is operation seismic surveys for oil/gas exploration academic studies. Large amounts are generated at a rate several Gigabits per second, by nearly 10,000–30,000 sensors that deploye...

Measuring acoustic backscatter in the water column is a low-cost, reliable method for examining the longterm behaviour and distribution of zooplankton populations. Backscatter at acoustic frequencies above 20 kHz is useful for profiling those quantities, which, when tracked over long periods of time, can provide a valuable contribution to understanding and monitoring the state of marine ecosyst...
