Methods in Ecology and Evolution, Volume 15, Issue 8, Page 1360-1379, August 2024.Abstract Global climate‐driven ocean warming has decreased dissolved oxygen (DO) levels (ocean deoxygenation) leading to expansions of hypoxic zones, which will affect the movements, behaviour, physiology and distributions of marine animals. However, the precise responses of animals to low DO remains poorly understood because movements and activity ...

Remote SensingTime-varying underwater acoustic (UWA) channels are the key challenge of underwater acoustic communication (UAC). Although UAC exhibits time-variance characteristics significantly in time domains, its delay-Doppler (DD) domain representation tends to be ...

Capacity of κ‐μ Shadowed Fading Channels
International Journal of Antennas and Propagation, Volume 2014, Issue 1, 2014., 2014 The ergodic capacity of fading channels modeled with a κ‐μ shadowed distribution is investigated to derive closed‐form expressions. The κ‐μ shadowed distribution is of particular interest because it contains, as special cases, other classical ones like one‐side Gaussian, Rayleigh, Rician, Nakagami‐m, κ‐μ, and Rician shadowed distributions.

Underwater acoustic communication messaging time stamp applied to global time synchronization
, 2014 This paper presents a new approach to time stamp messages in underwater acoustic communication. Message time stamping is a widely used method for synchronizing two clocks over a cabled or wireless communication, by exchanging time information in ...

Weathering the storm: developments in the acoustic sensing of wind and rain [PDF]
, 2003 An Acoustic Rain Gauge (ARG) analyses the underwater sound levels across a wide frequency range, classifies the observed spectrum according to likely source and then determines the local wind speed or rain rate as appropriate. Thispaper covers a trial on

Modified Green's Functions for Shallow Water Acoustic Wave Propagation [PDF]
, 2004 This article presents an assessment of alternative forms of the Green’s function for boundary element simulations of acoustic wave propagation in shallow water. It is assumed that the problem is two-dimensional, the source of acoustic disturbance is time-

A Secure Communication Suite for Underwater Acoustic Sensor Networks [PDF]
, 2012 In this paper we describe a security suite for Underwater Acoustic Sensor Networks comprising both fixed and mobile nodes. The security suite is composed of a secure routing protocol and a set of cryptographic primitives aimed at protecting the ...
