Animal geolocation with convolution algorithms in Julia and R via Wahoo.jl
Methods in Ecology and EvolutionAnimal geolocation is the core of movement ecology. In aquatic ecosystems, electronic tagging and tracking technologies, such as passive acoustic telemetry systems and biologging sensors, are widely deployed. However, statistical estimation of individual

Accuracy of using visual identification of white sharks to estimate residency patterns. [PDF]
PLoS ONE, 2012 Determining the residency of an aquatic species is important but challenging and it remains unclear what is the best sampling methodology. Photo-identification has been used extensively to estimate patterns of animals' residency and is arguably the most ...

Underwater Acoustic Telemetry [PDF]
The Journal of the Acoustical Society of America, 1961 Equipment developed for test and use in a feasibility study of an acoustic FM/FM telemetering system is described. The system employs two standard subcarrier oscillators at 0.96- and 1.3-kc frequency modulating a 40-kc carrier to provide channels of continuous information.

, 2003 Broadcasting messages through the earth is a daunting task. Indeed, broadcasting a normal telephone conversion through the earth by wireless means is impossible with todays technology. Most of us don't care, but some do. Industries that drill into the earth need wireless communication to broadcast navigation parameters.

High performance architecture design for large scale fibre-optic sensor arrays using distributed EDFAs and hybrid TDM/DWDM [PDF]
, 2013 A distributed amplified dense wavelength division multiplexing (DWDM) array architecture is presented for interferometric fibre optic sensor array systems. This architecture employs a distributed erbium doped fibre amplifier (EDFA) scheme to decrease the
