Underwater Visual Census at pilot oyster reefs in the Borkum Reef Ground marine protected area during HE601 (June 2022)

The Underwater Visual Census (UVC) transects were carried out by scientific divers during the Heincke HE601 cruise focusing on developing and testing monitoring techniques at the Borkum Reef Ground and Sylt Outer Reef Marine Protected Areas.

Underwater Image Enhancement Using An Integrated Colour Model. [PDF]

, 2007
In underwater situations, clarity of images are degraded by light absorption and scattering. This causes one colour to dominate the image.

Underwater visual census-derived fish biomass as a proxy for small-scale fisheries catch and revenue indicators

Mediterranean Marine Science
Empirical data about small-scale fishery indicators, such as catches and revenues, are generally scarce and scattered. In this study, we examined for the first time the relationships between fish biomass estimated through underwater visual census (UVC) and small-scale fishery indicators, namely catch per unit effort (CPUE) and revenue per unit effort ...

Detection heterogeneity in underwater visual-census data

This study shows how capture-mark-recapture (CMR) models can provide robust estimates of detection heterogeneity (sources of bias) in underwater visual-census data.

Characterisation of coastal reef fish assemblages across an estuarine-urbanisation gradient using underwater visual census and environmental DNA metabarcoding

Ecological Indicators
The ongoing urbanisation of coastlines around the globe greatly impacts biodiversity, including coastal marine fishes. In many places, baseline data on fish communities are inadequate for understanding and managing the ecological impacts of this ...

The Impact of the Latest 3D Technologies on the Documentation of Underwater Heritage Sites [PDF]

, 2013
Documenting underwater cultural heritage is a challenging undertaking. Underwater environment is not a man’s natural habitat and special equipment and devices had to be invented so that he could enter and study this environment.
