Continuous determination of dissolved inorganic carbon fluxes from pumping suspension feeders

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Suspension‐feeding organisms play a pivotal role in the cycling of carbon in the oceans. They filter large amounts of water, filter out organic matter, remineralize it, and release respiratory CO2 back into the water column. Measuring emissions of respiratory CO2 in situ from suspension feeders poses the challenge of detecting small changes in

The ICOS OTC pCO2 instrument intercomparison

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract In 2021, the Ocean Thematic Centre of the European Research Infrastructure “Integrated Carbon Observation System” conducted an international partial pressure of carbon dioxide (pCO2) instrument intercomparison. The goal was to understand how different types of instrumentation for the measurement of ocean pCO2 compare to each other.

Ion Chemistry in Dielectric Barrier Discharge Ionization: Recent Advances in Direct Gas Phase Analyses

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Dielectric barrier discharge ionization (DBDI) sources, employing low‐temperature plasma, have emerged as sensitive and efficient ionization tools with various atmospheric pressure ionization processes. In this review, we summarize a historical overview of the development of DBDI, highlighting key principles of gas‐phase ion chemistry and the ...

Test–Retest Reliability of Perception Threshold Estimation in Small Cutaneous Nerve Fibers: A Methodological Investigation

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Nerve excitability testing of small cutaneous nerve fibers has been proposed as a new tool for investigating the underlying mechanisms of small fiber neuropathy. These assessments may be performed using perception threshold tracking with pin‐electrodes that preferentially activate small cutaneous nerve fibers.
