A lightweight clear liquid optical chamber baited remote underwater video system for monitoring fish in turbid coastal wetlands

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Clear liquid optical chamber baited remote underwater video systems (CLOC‐BRUV) are an effective option for assessing fish assemblages in turbid water, but current designs are limited by their large size and high operational costs. We developed a lightweight CLOC‐BRUV unit and evaluated its performance through proof‐of‐concept trials and field

Uncertainty in aquatic greenhouse gas flux estimates arises from subjective processing of floating chamber time series

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Accurate quantification of greenhouse gas (GHG) fluxes from aquatic systems is essential for constraining regional and global carbon budgets. Closed floating chambers are widely used to measure carbon dioxide (CO2) and methane (CH4) fluxes at the water–air interface, yet large uncertainties persist due to subjective processing of chamber time ...
