Food availability impacts oxygen isotope composition in freshwater snail shells

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract Freshwater mollusk shells serve as valuable archives for the reconstruction of past environmental conditions as they record water temperatures in their stable isotopic compositions during biomineralization. Yet, the impact of food availability on these isotopic records has never been fully explored.

Seasonal Forecasts of pH and Aragonite Saturation for the Bering Sea Shelf

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.
Abstract The number of numerical model forecasts of ocean environmental conditions has greatly expanded in recent years, including biogeochemical variables. Forecasts can provide marine resource managers with advance warning of extreme events such as heatwaves and hypoxia, though forecast products are scarcer in high‐latitude environments.

Toughening of TiO2 via Femtosecond Laser Shock Peening

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Most ceramics have low fracture toughness (<5 MPa m$\sqrt{m}$) at room temperature. This work explores the feasibility of toughening TiO2 via femtosecond laser shock peening (fs‐LSP). Transmission electron microscopy (TEM) analyses reveal LSP‐induced the creation of high‐density stacking faults, dislocation structures, and twin boundaries in ...

Spherulite in the modern aragonitic travertine stromatolite has a calcite core with exopolymers

Sedimentology, Volume 73, Issue 5, Page 1421-1434, August 2026.
ABSTRACT Spherulites are spherical to ellipsoidal particles formed by various crystalline substances and can be abiotically synthesised in the laboratory. Among various spherulite types, spherulites composed of calcium carbonate are also found in various natural environments, but their abiotic or biotic origins are still controversial.

Source‐to‐sink sediment transport reversals during glacial sea‐level lowstands sustain soil formation on pericoastal carbonate terrains

Sedimentology, Volume 73, Issue 5, Page 1892-1910, August 2026.
ABSTRACT Understanding the processes that drive soil formation is crucial for developing sustainable land‐use strategies, as changing land‐use practices and climate change exacerbate soil erosion. The formation of substantial arable soils on carbonate bedrock requires substantial dust accretion as the underlying bedrock lacks siliciclastic material. In

Field and Experimental Observations Show Elevated Shear Strength of Active Margin Sediments Requires Processes Beyond Normal Consolidation

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Near‐seafloor marine sediments on active margins have been shown to be stronger than those on passive margins. However, the reasons for this are not fully understood. To investigate the role of intrinsic properties, we performed resedimentation and oedometer tests and measured undrained shear strength, grain size, mineralogy, and plasticity on

Are Time and Temperature the Simple Answer to the Dolomite Problem?

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Dolomite is among the most common carbonate minerals in ancient rocks but its formation is rarely observed today, a longstanding puzzle known as the “Dolomite Problem.” Recent advances in experimental mineralogy, geochemistry, and global abundance reconstructions have begun to resolve this problem.
