Performance of copper azole treated softwoods exposed to marine borers

open access: yesMaderas: Ciencia y Tecnología, 2016
Wooden material has been used for shipbuilding and structural purposes in the marine environment since ancient times. Wood being used in the sea water can be damaged by marine wood boring organisms, which can turn marine wooden structures unserviceable ...

Underwater Image Haze Removal and Color Correction with an Underwater-ready Dark Channel Prior [PDF]

open access: yesarXiv, 2018
Underwater images suffer from extremely unfavourable conditions. Light is heavily attenuated and scattered. Attenuation creates change in hue, scattering causes so called veiling light. General state of the art methods for enhancing image quality are either unreliable or cannot be easily used in underwater operations.

Soft Fluidic Closed-Loop Controller for Untethered Underwater Gliders [PDF]

open access: yesarXiv, 2023
Soft underwater robots typically explore bioinspired designs at the expense of power efficiency when compared to traditional underwater robots, which limits their practical use in real-world applications. We leverage a fluidic closed-loop controller to actuate a passive underwater glider.

Designing of Self‐Dispersing Soft Dendritic Microcleaners for Microplastics Capture and Recovery

open access: yesAdvanced Functional Materials, EarlyView.
The capture and recovery of microplastics from open aquatic systems is a complex problem, which necessitates nontrivial solutions. The principles of a comprehensive multistage process based on sustainably sourced microcleaners with hierarchical morphology are demonstrated.

Novel approach to studying marine fauna: using long-life remote underwater video cameras to assess occurrence and behaviour of threatened and data-deficient elasmobranch species in southern Mozambique

open access: yesFrontiers in Marine Science
Understanding the behaviour and ecological role of elasmobranchs is essential for their conservation, particularly in regions harbouring threatened and data-deficient species like the Inhambane coastline in southern Mozambique, southwestern Indian Ocean.

Scientific divers quantify first known outbreaks of cold-water coral disease [PDF]

open access: yes, 2009
Coral diseases are widely reported in the tropics but the first incidence of cold-water coral disease was not noted until 2002 when divers recorded an outbreak at 10-28 m depth off Lundy in a NE Atlantic marine protected area.

WQT and DG-YOLO: towards domain generalization in underwater object detection [PDF]

open access: yesarXiv, 2020
A General Underwater Object Detector (GUOD) should perform well on most of underwater circumstances. However, with limited underwater dataset, conventional object detection methods suffer from domain shift severely. This paper aims to build a GUOD with small underwater dataset with limited types of water quality.

Unsupervised haze removal from underwater images [PDF]

open access: yesarXiv, 2023
Several supervised networks exist that remove haze information from underwater images using paired datasets and pixel-wise loss functions. However, training these networks requires large amounts of paired data which is cumbersome, complex and time-consuming. Also, directly using adversarial and cycle consistency loss functions for unsupervised learning
