An automated system for trace gas flux measurements from plant foliage and other plant compartments [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
Plant shoots can act as sources or sinks of trace gases including methane and nitrous oxide. Accurate measurements of these trace gas fluxes require enclosing of shoots in closed non-steady-state chambers.

Atmospheric neutrinos with the first detection units of KM3NeT/ARCA [PDF]

open access: yesJournal of Instrumentation, 2021
Abstract The KM3NeT collaboration is constructing two deep-sea Cherenkov detectors in the Mediterranean Sea. The ARCA detector aims at TeV-PeV neutrino astronomy, while the ORCA detector is optimised for atmospheric neutrino oscillation studies at energies of a few GeV.

Novel Mitochondrial DNA Markers for Scleractinian Corals and Generic-Level Environmental DNA Metabarcoding

open access: yesFrontiers in Marine Science, 2021
Coral reefs, the most biodiverse habitats in the ocean, are formed by anthozoan cnidarians, the scleractinian corals. Recently, however, ongoing climate change has imperiled scleractinian corals and coral reef environments are changing drastically. Thus,

Unexpectedly high ultrafine aerosol concentrations above East Antarctic sea ice [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Better characterisation of aerosol processes in pristine, natural environments, such as Antarctica, have recently been shown to lead to the largest reduction in uncertainties in our understanding of radiative forcing.

Divalent metal transporter-related protein restricts animals to marine habitats

open access: yesCommunications Biology, 2021
Mieko Sassa et al. report a novel divalent metal transporter protein (DMTRP) in the crown-of-thorns starfish genome and determine that all organisms with a DMTRP gene are located in marine habitats.

Transparent Exopolymer Particles in Deep Oceans: Synthesis and Future Challenges

open access: yesGels, 2021
Transparent exopolymer particles (TEP) are a class of abundant gel-like particles that are omnipresent in seawater. While versatile roles of TEP in the regulation of carbon cycles have been studied extensively over the past three decades, investigators ...
