Using water‐landing, fixed‐wing UAVs and computer vision to assess seabird nutrient subsidy effects on sharks and rays

Autor: Melissa Schiele, J. Marcus Rowcliffe, Ben Clark, Paul Lepper, Tom B. Letessier

Publikováno v: Remote Sensing in Ecology and Conservation, Vol 10, Iss 3, Pp 416-430 (2024)

Abstract Bird colonies on islands sustain elevated productivity and biomass on adjacent reefs, through nutrient subsidies. However, the implications of this localized enhancement on higher and often more mobile trophic levels (such as sharks and rays

Autonomous Deployment of Underwater Acoustic Monitoring Devices Using an Unmanned Aerial Vehicle: The Flying Hydrophone

Autor: Daniel Babatunde, Simon Pomeroy, Paul Lepper, Ben Clark, Rebecca Walker

Publikováno v: Sensors, Vol 20, Iss 21, p 6064 (2020)

Unmanned aerial vehicles (UAV) are increasingly becoming a popular tool in the observation and study of marine mammals. However, the potential capabilities of these vehicles regarding autonomous operations are not being fully exploited for passive un

Commute mode choice dynamics: Accounting for day-to-day variability in longer term change

Autor: Kiron Chatterjee, Ben Clark, Caroline Bartle

Publikováno v: European Journal of Transport and Infrastructure Research, Vol 16, Iss 4 (2016)

It is of interest to transport policy makers to know whether interventions promoting sustainable transport modes can produce long-term changes in commute mode choices. Recent evidence has shown that a significant minority of commuters are variable in

Acoustical Direction Finding with Time-Modulated Arrays

Autor: Ben Clark, James A. Flint

Publikováno v: Sensors, Vol 16, Iss 12, p 2107 (2016)

Time-Modulated Linear Arrays (TMLAs) offer useful efficiency savings over conventional phased arrays when applied in parameter estimation applications. The present paper considers the application of TMLAs to acoustic systems and proposes an algorithm

Pumice cone eruptions at Aluto volcano, Ethiopia

Autor: Ben Clarke, Eliza S. Calder, Karen Fontijn, Firawalin Desalegn, Pablo Tierz, Gezahegn Yirgu

Publikováno v: Volcanica, Vol 7, Iss 2, Pp 785-811 (2024)

Pumice cones are volcanic landforms that exist worldwide, but whose eruption has never been observed. Interpretations of these eruptions vary significantly in style, intensity, and magnitude, pertinent for volcanic hazard assessment. Aluto volcano (E
