Side-Scan Sonar Image Segmentation Based on Multi-Channel CNN for AUV Navigation

open access: yesFrontiers in Neurorobotics, 2022
The AUV (Autonomous Underwater Vehicle) navigation process relies on the interaction of a variety of sensors. The side-scan sonar can collect underwater images and obtain semantic underwater environment information after processing, which will help ...

Evaluating drivers of recent large whale strandings on the East Coast of the United States

open access: yesConservation Biology, Volume 38, Issue 6, December 2024.
Abstract Anthropogenic stressors threaten large whales globally. Effective management requires an understanding of where, when, and why threats are occurring. Strandings data provide key information on geographic hotspots of risk and the relative importance of various threats.

My father put them up there: Anthropogenic environmental change associated with abandoned river vessels in the Clarence River, NSW, Australia

open access: yesRiver Research and Applications, Volume 40, Issue 9, Page 1719-1731, November 2024.
Abstract The Clarence River (New South Wales, Australia) was the main transport corridor for the timber and sugar cane industries operating in the catchment from the 1860s to the 1970s. Using archaeological, documentary, and oral historical resources we explore some of the anthropogenic impacts of these industries upon the fluvial geomorphology of the ...

Optimising collection geometry for long‐range synthetic aperture sonar interferometry

open access: yesIET Radar, Sonar &Navigation, Volume 18, Issue 11, Page 2034-2043, November 2024.
A technique is presented to optimise data collection geometry in synthetic aperture sonar interferometry. This can be used to maximise the area coverage rate in seabed imaging and mapping. Abstract Interferometric synthetic aperture sonar (SAS) is a technique to image and map the seabed in very high resolution. For large area coverage rate systems with
