Investigations into Ultra-Low-Power Underwater Imaging
Imaging underwater environments is crucial to advancing our understanding of marine organisms, climate change, marine geology, aquaculture farming, and underwater archaeology. Despite significant advances in underwater imaging, scalable and longterm imaging of underwater environments is still an …

Field deployable dynamic lighting system for turbid water imaging
… depths provide an ever changing and complex imaging environment. As scientists and researches strive to document and study more remote and optically challenging areas, specifically scatter-limited environments. There is a requirement for new illumination systems that improve both image …

Large-area visually augmented navigation for autonomous underwater vehicles
… imagery constraints typical of autonomous underwater vehicles (AUVs) while exploiting the inertial sensor information that is routinely available on such platforms. We adopt a systems-level approach exploiting the complementary aspects of inertial sensing and visual perception from a …

An investigation into the characteristics and sources of light emission at deep-sea hydrothermal vents
A spectral camera (ALISS - Ambient Light Imaging and Spectral System) was used to image ambient light from high-temperature vents at 9°N East Pacific Rise and the Juan de Fuca Ridge during 1997 and 1998 Alvin dive cruises. ALISS is a low-light digital camera with custom-designed optics. A set of …
