Multi-year time series of daily solute and isotope measurements from three Swiss pre-Alpine catchments

Time series analyses of solute concentrations in streamwater and precipitation are powerful tools for unraveling the interplay of hydrological and biogeochemical processes at the catchment scale. While such datasets are available for many sites around the ...

Consider the Anoxic Microsite: Acknowledging and Appreciating Spatiotemporal Redox Heterogeneity in Soils and Sediments

Meret Aeppli, Vincent Noel

Reduction-oxidation (redox) reactions underlie essentially all biogeochemical cycles. Like most soil properties and processes, redox is spatiotemporally heterogeneous. However, unlike other soil features, redox heterogeneity has yet to be incorporated into ...

Climatic and Ecological Impact of Greenlandic Glacial Outwash Plains

Devis Tuia, Julia Schmale, Nora Bergner, Ianina Altshuler, Gaston Jean Lenczner, Grace Emma Marsh

Warming in the Arctic is occurring at an accelerated rate compared to the rest of the world which is partially driven by ecological and climatic feedback loops. Accelerated glacial and ice sheet retreat in Greenland drives increased development of glacial ...

Towards an improved understanding of biogeochemical processes across surface-groundwater interactions in intermittent rivers and ephemeral streams

Luis Gómez Gener, Oleksandra Shumilova

Surface-groundwater interactions in intermittent rivers and ephemeral streams (IRES), waterways which do not flow year-round, are spatially and temporally dynamic because of alternations between flowing, non-flowing and dry hydrological states. Interaction ...

Variability in arsenic methylation efficiency across aerobic and anaerobic microorganisms

Rizlan Bernier-Latmani, Karin Lederballe Meibom, Karen Elda Viacava Romo, Arnaud Michel Gelb, Leia Soraya Véronique Falquet, Shannon Eliot Dyer, Adrien Mestrot

Microbially-mediated methylation of arsenic (As) plays an important role in the As biogeochemical cycle, particularly in rice paddy soils where methylated As, generated microbially, is translocated into rice grains. The presence of the arsenite (As(III)) m ...

Patterns and Drivers of Extracellular Enzyme Activity in New Zealand Glacier-Fed Streams

Tom Ian Battin, Hannes Markus Peter, Susheel Bhanu Busi, Tyler Joe Kohler, Stylianos Fodelianakis, Paraskevi Pramateftaki, Vincent Henri De Staercke, Matteo Tolosano, Michail Styllas, Martina Andrea Schön

Glacier-fed streams (GFSs) exhibit near-freezing temperatures, variable flows, and often high turbidities. Currently, the rapid shrinkage of mountain glaciers is altering the delivery of meltwater, solutes, and particulate matter to GFSs, with unknown cons ...

Travel Time and Source Variation Explain the Molecular Transformation of Dissolved Organic Matter in an Alpine Stream Network

Tom Ian Battin, Hannes Markus Peter, Amber Joy Ulseth

Streams and rivers are important components of the carbon cycle as they transport and transform dissolved organic matter (DOM). Using high resolution Fourier transform ion cyclotron resonance mass spectrometry, we studied the spatial distribution of DOM at ...

Toward catchment hydro-biogeochemical theories

Andrea Rinaldo, Paolo Benettin, Ilja van Meerveld, Li Li

Headwater catchments are the fundamental units that connect the land to the ocean. Hydrological flow and biogeochemical processes are intricately coupled, yet their respective sciences have progressed without much integration. Reaction kinetic theories tha ...
