Underwater acoustic glider

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
Underwater gliders are buoyancy-driven devices; they alternately reduce and expand displaced volume to dive and climb through the ocean. Gliders carry wings and control their pitch attitude to effectuate a horizontal speed component through the ocean. They turn by rolling their wings or by use of a rudder.

On Multicasting in Underwater Acoustic Networks

2015 IEEE Global Communications Conference (GLOBECOM), 2014
Even though underwater acoustic communication suffers from long propagation delays and has very limited bandwidth, it still plays a key role in supporting long-distance, low-power communication in underwater sensor networks. Many previous studies have tried to mitigate the impact of long propagation delays, but recently, the focus has shifted from ...

Underwater acoustic beam dynamics

The Journal of the Acoustical Society of America, 2009
Ray- and mode-based theoretical predictions of the spreads of directionally narrow beams are presented and compared to parabolic-equation-based simulations in deep-ocean environments. Both the spatial and temporal spreads of beams are considered. The environments considered consist of a range-independent deep-ocean background sound channel on which a ...
