Toward a Harmonization for Using in situ Nutrient Sensors in the Marine Environment.
(2020)
Improved comparability of nutrient concentrations in seawater is required to enhance the
quality and utility of measurements reported to global databases. Significant progress
has been made over recent decades in improving ...
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 ...
A Regional Neural Network Approach to Estimate Water-Column Nutrient Concentrations and Carbonate System Variables in the Mediterranean Sea: CANYON-MED.
(2020)
A regional neural network-based method, “CANYON-MED” is developed to estimate nutrients and carbonate system variables specifically in the Mediterranean Sea over the water column from pressure, temperature, ...
Method for Reproducible Shipboard Segmented Flow Analysis Ammonium Measurement using an In-House Reference Material for Quality Control.
(2021)
Ammonium is a fundamental nutrient for phytoplankton growth in seawater and is a key component of the microbial loop. Ammonium measured in parallel with other nutrients is crucial in understanding the small temporal scale ...
Tracks in the Snow – Advantage of Combining Optical Methods to Characterize Marine Particles and Aggregates.
(2020)
Settling marine aggregates, such as zooplankton fecal pellets and marine snow,
transport organic matter from the surface ocean to the deep sea and are largely
responsible for the ocean’s sequestration of carbon. However, ...
Protocols for Assessing Transformation Rates of Nitrous Oxide in the Water Column.
(2021)
Nitrous oxide (N2O) is a potent greenhouse gas and an ozone destroying substance.
Yet, clear step-by-step protocols to measure N2O transformation rates in freshwater
and marine environments are still lacking, challenging ...
A vision for FAIR ocean data products.
(2021)
The ocean is mitigating global warming by absorbing large amounts of excesscarbon dioxide from human activities. To quantify and monitor the ocean carbonsink, we need a state-of-the-art data resource that makes data ...
New and updated global empirical seawater property estimation routines.
(2021)
We introduce three new Empirical Seawater Property Estimation Routines (ESPERs) capable of predicting seawater
phosphate, nitrate, silicate, oxygen, total titration seawater alkalinity, total hydrogen scale pH (pHT), ...
Long-term intercomparison of two pCO2 instruments based on ship-of-opportunity measurements in a dynamic shelf sea environment.
(2021)
The partial pressure of carbon dioxide (pCO2) in surface seawater is an important biogeochemical variable
because, together with the pCO2 in the atmosphere, it determines the direction of air–sea carbon dioxide
exchange. ...
Advancing best practices for assessing trends of ocean acidification time series.
(2022)
Assessing the status of ocean acidification across ocean and coastal waters
requires standardized procedures at all levels of data collection, dissemination,
and analysis. Standardized procedures for assuring quality and ...
