Integrating climate data and river modeling to reveal Chinook salmon habitat conditions in subarctic river basins

Ecosphere, Volume 17, Issue 1, January 2026.
Abstract Climatic extremes can impact the productivity of aquatic species, affecting ecosystems and fishery‐dependent communities. Advances in climate products, such as gridded datasets and downscaled projections, may be useful for quantifying freshwater habitat conditions and predicting climate change effects on fish.

Stable carbon isotopes of methane reveal that the central Arctic Ocean is a potential sink of atmospheric methane

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Marine methane emissions are important components of natural methane budgets, but the methane emission contribution derived from the central Arctic is still unclear. Here, we measured the dissolved methane concentration and its stable carbon isotopic signature (δ13C‐CH4) while onboard a western Arctic cruise in 2024.

Clumped isotopes as fingerprints of microbial methane production pathways in marine sediments

Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Microbial methanogenesis in marine sediments produces significant amounts of methane from various substrates; however, identifying the active pathways in situ remains challenging. While the bulk and clumped isotopic signatures of methane from different pathways have been studied in pure cultures, these are difficult to compare with complex ...
