Demonstration, validation, and application of hyperspectral microscopy for the collection of cyanobacterial spectral signatures

Limnology and Oceanography: Methods, Volume 24, Issue 6, June 2026.
Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.

Iron Fertilization of the North Pacific Did Not Drive Long‐Term Pliocene to Quaternary Cooling

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract While several hypotheses exist to explain the development of large‐scale perennial Northern Hemisphere ice sheets in the late Pliocene and early Pleistocene, the prevailing view is that a decline in atmospheric carbon dioxide (CO2) drove this substantial change in late Neogene climate.

Trace Metal Biogeochemistry in the Nordic Seas: Arctic and Atlantic Water Inflows Determine (Micro)Nutrient Availability

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract We present a data set of macronutrient and dissolved and total dissolvable trace metal concentrations collected in June 2012 across the Nordic Seas. Surface water and depth profiles of manganese, iron, cobalt, nickel, copper, zinc, phosphate, silicic acid, and NOx (nitrate + nitrite) reveal how warm saline Atlantic waters and cold fresh Arctic

East‐West Variability in Nitrogen Sources Sustaining Pelagic Food Webs in the Subtropical North Pacific Ocean Revealed by Stable Isotopic Analyses

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Biological N2 fixation sustains pelagic ecosystems in subtropical oligotrophic waters. However, its impact on food webs as a nitrogen source remains poorly understood. Here, we quantified the contribution of diazotroph‐derived nitrogen to grazing food chains in the subtropical North Pacific in summer, where N2 fixation activity varies markedly

Multidisciplinary Investigation of Healy Submarine Volcano (Kermadec Arc, New Zealand) Using AUV and Submersible Data: Structural Control on Magmatic and Hydrothermal Processes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract We present a comprehensive multidisciplinary investigation of the Healy submarine volcano in the southern Kermadec arc, northeast of New Zealand. We show the first results of sidescan‐sonar data collected at a submarine arc volcano by an Autonomous Underwater Vehicle (AUV).

Eastward Growth of the Tibetan Plateau Linked to Cenozoic Orogenic Wedge Deformation and Fluctuating Melt Sources

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The India–Asia collision continuously loads the Tibetan Plateau (TP), driving its Cenozoic eastward growth. This process has caused extensive crustal deformation and a diverse magmatic response. Here, we report on newly identified 35−6.5 Ma granitoids from Kangding area in southeastern (SE) TP.

Cajon Pass and the Southern San Andreas Fault System: Earthquake Cycle Stress Accumulation and Present‐Day Loading

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract With over a century since the last major rupture affecting the wider Los Angeles region, tectonic stress has steadily built along the southern San Andreas and San Jacinto fault systems, raising concerns of an imminent large earthquake. Cajon Pass, located at the junction of these faults, represents a critical site for potential through‐going ...

Impact and Crystallization Modeling of the Sudbury Basin and Its Implications for a Hadean Crust

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The 1.85 Ga Sudbury Structure hosts Earth's largest and best‐preserved impact‐induced melt sheet, the Sudbury Igneous Complex (SIC), which crystallized into distinct noritic, gabbroic, and granophyric layers. We conduct impact simulations with iSALE‐2D and crystallization modeling using alphaMELTS 2 to track the formation and evolution of the ...

Alteration of Feldspar‐Rich Rocks on Ancient Mars and Its Possible Link to Ca/Fe‐Rich Carbonates

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Feldspar‐rich rocks have increasingly been discovered on the martian surface. They may have been an important part of the ancient martian crust and may be related to Ca/Fe‐rich carbonates (one of two types of carbonates on Mars and the other being Mg‐rich carbonates), but compared to mafic rocks, their interaction with water on ancient Mars is
