A Lab-On-Chip Phosphate Analyzer for Long-term In Situ Monitoring at Fixed Observatories: Optimization and Performance Evaluation in Estuarine and Oligotrophic Coastal Waters,
(2017)
The development of phosphate sensors suitable for long-term in situ deployments
in natural waters, is essential to improve our understanding of the distribution,
fluxes, and biogeochemical role of this key nutrient in a ...
Estimating Uncertainties in Oceanographic Trace Element Measurements.
(2019)
A realistic estimation of uncertainty is an essential requirement for all analytical
measurements. It is common practice, however, for the uncertainty estimate of a
chemical measurement to be based on the instrumental ...
Best practices for use of stable isotope mixing models in food-web studies.
(2014)
Stable isotope mixing models are increasingly used to quantify consumer diets, but may be misused and misinterpreted. We address major challenges to their effective application. Mixing models have increased rapidly in ...
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 [Vols 1-10].[SUPERSEDED by DOI: http://dx.doi.org/10.25607/OBP-772]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 ...
Comparison of ten packages that compute ocean carbonate chemistry.
(2015)
Marine scientists often use two measured or modeled carbonate system variables to compute others. These
carbonate chemistry calculations, based on well-known thermodynamic equilibria, are now available in a ...
Routine uncertainty propagation for the marine carbon dioxide system.
(2018)
Pairs of marine carbonate system variables are often used to calculate others, but those results are seldom reported with estimates of uncertainties. Although the procedure to propagate these uncertainties is well known, ...
Manual de Referencia en Mejores Prácticas de Gestión de Datos Oceánicos. Número 1/2016.
(Dirección General Marítima, Bogotá D.C., Colombia, 2016)
The “Colombian Oceanographic Data and Information Coordination Committee” (CTN Diocean, by its initials in Spanish) was created by Resolution No. 005/2015 of the Colombian Ocean Commission (CCO, by its initials in Spanish), ...
Interpretation of complexometric titration data: an intercomparison of methods for estimating models of trace metal complexation by natural organic ligands.
(2015)
With the common goal of more accurately and consistently quantifying ambient concentrationsof free metal ions
and natural organic ligands in aquatic ecosystems, researchers from 15 laboratories that routinely analyze ...
Fe- and Cu-Complex Formation with Artificial Ligands Investigated by Ultra-High Resolution Fourier-Transform ion Cyclotron Resonance Mass Spectrometry (FT-ICR-MS): Implications for Natural Metal-Organic Complex Studies.
(2016)
In recent years, electrospray-ionization mass spectrometry (ESI-MS) has been increasingly used to complement the bulk determination of metal-ligand equilibria, for example via competitive ligand exchange-adsorptive cathodic ...
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 ...
