Distribution and source‐sink dynamics of H2 in the Western Tropical Pacific and their response to La Niña–induced upwelling

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Hydrogen (H2) influences the climate by prolonging the lifetime of greenhouse gases via consuming hydroxyl radicals. Despite the ocean's crucial role in regulating atmospheric H2, its marine biogeochemical cycle is poorly constrained. To bridge this gap, our research in the Western Tropical Pacific Ocean (WTPO) revealed a north–south ...

Divergent responses of the diatom Thalassiosira weissflogii to ocean acidification during light and dark periods

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Given the limited understanding of discrepancies in responses of diatoms to ocean acidification (OA), we comparatively investigated the physiological and transcriptional performances of a diatom Thalassiosira weissflogii acclimated to OA (pHt drop of 0.35–0.41) between day and night periods.

Comparison between fluorometry and microscopy‐based phytoplankton assessments in the Laurentian Great Lakes

Limnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.
Abstract Photosynthetic pigment fluorescence is commonly used in limnology and oceanography as a proxy for phytoplankton biomass. Fluorometry has been used to detect subsurface algal blooms, characterize dynamics of the deep chlorophyll layer, and to provide greater vertical resolution to phytoplankton monitoring.

Microbial Controls on Carbon Pump Partitioning in the Subtropical North Atlantic: Stoichiometry and Nutrient Limitation Across a Basin‐Scale Transect

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract The subtropical North Atlantic is a key region for ocean carbon cycling despite its relatively small spatial extent. Here we present a high‐resolution transect (23°–27°N; ∼2° longitude spacing) across the North Atlantic Subtropical Gyre, integrating physical, chemical, and microbial observations to examine how hydrography and nutrient ...

Hydromagnesite Precipitation in an Ultramafic‐Hosted Alkaline Lake: Insights From Lake Salda for Jezero Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Lake Salda (SW Turkey) is one of the most compelling terrestrial analogs for Jezero Crater on Mars due to its highly alkaline, Mg‐rich waters and hydromagnesite‐forming microbialites. This study integrates hydrochemical measurements, saturation‐index modeling, SEM–TEM imaging, and X‐ray diffraction (XRD) analysis to disentangle the biotic and ...

Putative Analogs of Pyrite Suns Forming in Proglacial Alaska Mudflats

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Disc‐shaped pyrite suns of the Pennsylvanian age Anna Shale are thought to have formed where pressure restricted pyrite crystal growth to a flattened disc shape during diagenesis at the Anna Shale and the underlying Herrin coal boundary.
