Autonomous systems, including gliders, floats, and propeller-driven AUVs, require navigation under Arctic ice to be able to geolocate during their missions. In addition, acoustic communications provides for unidirectional or bidirectional data and co

A small experimental network of ocean sensors linked by acoustic communications was tested in March-April of 2017 in shore-fast ice near Thule Air Base in northern Greenland. The objective was to simultaneously test a real-time communications system

A bottom-to-bottom acoustic communications network is feasible in areas of the ocean where the combination of the depth and near-surface sound speed support direct-path refracted rays which connect multiple sensor nodes located on or near the seafloo

In this Letter we describe a beamforming video recorder consisting of a video camera at the center of a 16 hydrophone array. A broadband frequency-domain beamforming algorithm is used to estimate the azimuth and elevation of each detected sound. Thes
