Inferring activity patterns of aquatic animals from single‐receiver acoustic telemetry setups
Methods in Ecology and Evolution, Volume 16, Issue 12, Page 2931-2944, December 2025.Abstract Acoustic telemetry has become an essential tool for studying activity patterns of animals in aquatic environments. Activity is typically recorded using transmitters with integrated sensors or dense receiver arrays for positional tracking. While effective, these approaches are financially and logistically expensive due to the need for advanced ...

The influences of environmental conditions on source localisation using a single vertical array and their exploitation through ground effect inversion [PDF]
, 2010 The performance of microphone arrays outdoors is influenced by the environmental conditions. Numerical simulations indicate that, while horizontal arrays are hardly affected, direction-of-arrival (DOA) estimation with vertical arrays becomes biased in ...

Outbreak of Gigantic Jets Over an Isolated Thunderstorm in South China
Earth and Space Science, Volume 12, Issue 10, October 2025.Abstract On the evening of 18 August 2022, a sequence of five gigantic jets (GJs) were recorded within 7 min over an isolated coastal thunderstorm approximately 170 km to the southwest of Luoding County, Guangdong Province of China. The thunderstorm exhibited a higher −10°C isotherm altitude (500 m above average), a significant CAPE value (∼2,158 J/kg),

Reflection-Aware Sound Source Localization
, 2017 We present a novel, reflection-aware method for 3D sound localization in indoor environments. Unlike prior approaches, which are mainly based on continuous sound signals from a stationary source, our formulation is designed to localize the position ...
