Adding Oxygen to Argo: Developing a Global In Situ Observatory for Ocean Deoxygenation and Biogeochemistry.
(European Space Agency, Paris, France, 2010)We propose to add dissolved oxygen sensors to the Argo (Global array of free-drifting profiling floats)float program in order to determine, on a global-scale, seasonal to decadal time-scale ... -
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 ... -
Assimilation of coastal and open sea biogeochemical data to improve phytoplankton simulation in the Mediterranean Sea.
(2018)The high spatial and temporal variability of biogeochemical features, induced by local dynamics and terrestrial and atmospheric inputs in shelf seas, are challenging issues for the implementation of data assimilation in ... -
Biogeochemical protocols and diagnostics for the CMIP6 Ocean Model Intercomparison Project (OMIP).
(2017)The Ocean Model Intercomparison Project (OMIP) focuses on the physics and biogeochemistry of the ocean component of Earth system models participating in the sixth phase of the Coupled Model Intercomparison Project (CMIP6). ... -
Building the capacity for forecasting marine biogeochemistry and ecosystems: recent advances and future developments.
(2015)Building the capacity for monitoring and forecasting marine biogeochemistry and ecosystem dynamics is a scientific challenge of strategic importance in the context of rapid environmental change and growing public awareness ... -
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 ... -
A Comparison between Four Analytical Methods for the Measurement of Fe(II) at Nanomolar Concentrations in Coastal Seawater.
(2017)Dissolved Fe(II) in seawater is deemed an important micronutrient for microbial organisms, but its analysis is challenging due to its transient nature. We conducted a series of Fe(II) method comparison experiments, where ... -
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 ... -
Determination of ultra-low oxygen concentrations in oxygen minimum zones by the STOX sensor.
(2009)The methods used until now have not been able to reliably resolve O2 concentrations in oceanic oxygen minimum zones below 1–2 µmol L−1. We present a new amperometric sensor for the determination of ultra‐low O2 concentrations ... -
Developments in marine pCO2 measurement technology; towards sustained in situ observations.
(2017)The oceanic uptake of anthropogenic CO2 causes pronounced changes to the marine carbonate system. High quality pCO2 measurements with good temporal and spatial coverage are required to monitor the oceanic uptake, identify ... -
The Dissolved Oxygen Handbook: a practical guide to dissolved oxygen measurements.
(YSI Incorporated, 2009)This booklet describes in detail the different types of dissolved oxygen sensing technologies available. It also covers, in general terms, recommended calibration methods, regular maintenance procedures that can be ... -
Evaluation of a lifetime‐based optode to measure oxygen in aquatic systems.
(2006)In this article, we evaluate the performance of a commercially available lifetime‐based optode and compare it with data obtained by other methods. We performed a set of 10 different tests, including targeted laboratory ... -
Evaluation of marine pH sensors under controlled and natural conditions for the Wendy Schmidt Ocean Health XPRIZE.
(2017)The annual anthropogenic ocean carbon uptake of 2.6 plus or minus 0.5 Gt C is changing ocean composition (e.g., pH) at unprecedented rates, but our ability to track this trend effectively across various ocean ecosystems ... -
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 ... -
Guideline of ocean observations, Volumes 1-10. 4th edition.
(The Oceanographic Society of Japan, Tokyo, Japan, 2020)The Oceanographic Society of Japan published the first edition of Guideline of Ocean Observations in September 2015 with an overview of oceanographic observations and the latest oceanographic and analytical methods. This ... -
Guideline of ocean observations. 1st edition. [Vols 1-10].[SUPERSEDED by DOI: http://dx.doi.org/10.25607/OBP-772]
(The Oceanographic Society of Japan, Tokyo, Japan, 2016)In recent years we have been building our knowledge of changes within the oceans through international cooperation and collaboration, for example, by re-occupation of World Ocean Circulation Experiment (WOCE); our ... -
