Protocol for Microplastics Sampling on the Sea Surface and Sample Analysis. [video article]
(2016)
Microplastic pollution in the marine environment is a scientific topic that has received increasing attention over the last decade. The majority of
scientific publications address microplastic pollution of the sea surface. ...
An evaluation of the performance of Sea-Bird Scientific’s SeaFET™ autonomous pH sensor: considerations for the broader oceanographic community.
(2018)
The commercially available Sea-Bird SeaFET™
provides an accessible way for a broad community of researchers to study ocean acidification and obtain robust measurements of seawater pH via the use of an in situ autonomous ...
Metrological challenges for measurements of key climatological observables: Oceanic salinity and pH, and atmospheric humidity. Part 1: Overview.
(2016)
Water in its three ambient phases plays the central thermodynamic role in the terrestrial climate
system. Clouds control Earth’s radiation balance, atmospheric water vapour is the strongest
“greenhouse” gas, and ...
In situ quantification of ultra-low O2 concentrations in oxygen minimum zones: Application of novel optodes.
(2016)
Conventional sensors for the quantification of O2 availability in aquatic environments typically have limits of detection (LOD) of > 1 μmol L−1 and do not have sufficient resolution to reliably measure concentrations in ...
Simulation and assimilation of global ocean pCO2 and air–sea CO2 fluxes using ship observations of surface ocean pCO2 in a simplified biogeochemical offline model.
(2010)
We used an offline tracer transport model, driven by reanalysis ocean currents and coupled to a simple biogeochemical
model, to synthesize the surface ocean pCO2 and air–sea CO2 flux of the global ocean from 1996 to 2004, ...
A climatology‐based quality control procedure for profiling float oxygen data.
(2013)
Over 450 Argo profiling floats equipped with oxygen sensors have been deployed, but no quality control (QC) protocols have been adopted by the oceanographic community for use by Argo data centers. As a consequence, the ...
Design and Application of an Optical Sensor for Simultaneous Imaging of pH and Dissolved O2 with Low Cross-Talk.
(2016)
Visualization and quantification of analytes such as O2 or pH is essential in biological research. Here we present the design and application of a new optical dual-analyte sensor for imaging, optimized to have low ...
Guidelines for Measuring Changes in Seawater pH and Associated Carbonate Chemistry in Coastal Environments of the Eastern United States.
(U.S. Environmental Protection Agency, Narragansett, RI, 2018)
These guidelines are written for a variety of audiences ranging from shellfish growers
interested in monitoring pH with inexpensive equipment to citizen monitoring groups to
advanced chemistry laboratories interested in ...
Air Oxygen Calibration of Oxygen Optodes on a Profiling Float Array.
(2015)
Aanderaa optode sensors for dissolved oxygen show remarkable stability when deployed on profiling floats, but these sensors suffer from poor calibration because of an apparent drift during storage (storage drift). It has ...
Towards Chip-Based Salinity Measurements for Small Submersibles and Biologgers.
(2013)
Water’s salinity plays an important role in the environment. It can be determined by measuring conductivity, temperature, and
depth (CTD). The corresponding sensor systems are commonly large and cumbersome. Here, a 7.5 × ...
