An autonomous and economical benthic incubation chamber for measuring dissolved oxygen fluxes in shallow, low‐flow environments

Limnology and Oceanography: Methods, EarlyView.
Abstract Benthic incubation chambers enclose a known volume of water overlying a known area to measure water chemistry changes and are typically used to quantify the metabolic activity of benthic organisms or communities. Here we present an economical benthic incubation chamber for shallow, low‐flow environments, built using off‐the‐shelf components ...

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

Limnology 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

Performance of a glider‐mounted multifrequency echosounder for measuring the vertical distribution and abundance of large pelagic copepods

Limnology and Oceanography: Methods, EarlyView.
Abstract The difficulty of sampling zooplankton communities in situ has driven advancements in autonomous, remote sensing technology. The goal of this paper was to perform a gear comparison study testing the performance of one such piece of technology—a glider‐mounted four‐frequency echosounder—against traditional shipboard methods of measuring ...

Red, green, blue color indices as proxy for Symbiodiniaceae cell density and chlorophyll content during coral bleaching

Limnology and Oceanography: Methods, EarlyView.
Abstract Coral bleaching, the breakdown of the symbiosis between the coral host and endosymbiotic microalgae, is the main cause of widespread coral reef degradation. Current visual assessment methods for coral health, including color reference cards, are constrained by subjective human color perception and limited resolution.

Applicability of the steady‐state oxygen stable isotope method for estimating metabolism in low‐productivity Arctic lakes

Limnology and Oceanography: Methods, EarlyView.
Abstract Metabolism is a key property of lake ecosystem functioning, but logistical challenges make it difficult to estimate across remote regions. The steady‐state dissolved oxygen (DO) stable isotope method (18O method) estimates metabolism from discrete water samples and thus enables large‐scale surveys.
