Ocean acidification at the crossroads I: Harmonizing unpurified and purified meta‐cresol purple spectrophotometric pHT measurements based on absorbance data

Limnology and Oceanography: Methods, EarlyView.
Abstract Consistent monitoring of seawater spectrophotometric pH on the total hydrogen ion scale (pHT) has been questioned by an evolving method, with changes in parameterization and the purity of the meta‐cresol purple (mCP). Using real seawater samples, we demonstrate that spectrophotometric pHT measurements obtained with unpurified (UNPUR) and ...

The ecology and conservation of green turtles (Chelonia mydas) in New Zealand : a thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Marine Ecology at Massey University, Albany, New Zealand [PDF]

, 2016
Historically, little consideration has been given to the occurrence, ecology or conservation of the green turtle (Chelonia mydas) in temperate New Zealand. Located geographically at the southern boundary of the distributional range of green turtles in

PNNL‐TUNAMELT: Toward automating the detection of interactions with marine energy devices using acoustic camera sensors

Limnology and Oceanography: Methods, EarlyView.
Abstract Acoustic cameras, or imaging sonars, are often used to monitor marine energy sites in regions where the water is too dark or turbid for optical sensing. To do so more effectively, scientists are investigating automated detection methodologies to use on these data.

Sediment trap preservative choice impacts particle‐associated microbial community composition

Limnology and Oceanography: Methods, EarlyView.
Abstract Understanding and quantifying the microbial contribution to particulate organic matter (POM) flux and carbon cycling in the ocean relies largely on the collection of sinking POM. A critical aspect of evaluating microbial communities on sediment trap‐collected POM is their preservation until recovery and sample processing.

Seabed classification in the Gulf of Alaska from acoustic surveys using deep learning

Limnology and Oceanography: Methods, EarlyView.
Abstract High‐resolution mapping of seafloor habitats has wide applications for fisheries, conservation efforts, offshore infrastructure planning, mineral extraction, and scientific modeling. This study leverages existing widespread single‐beam acoustic data and machine learning to create habitat maps for the Gulf of Alaska at a spatial resolution of ...

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 ...
