Demonstration, validation, and application of hyperspectral microscopy for the collection of cyanobacterial spectral signatures

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.

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

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

open access: yesLimnology 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 ...
