Neoarchean Arc Magmatism and Crust Recycling in the Northern Marginal Zone of the Limpopo Complex, Zimbabwe: New Insights From Zircon U‐Pb‐Hf Isotopes of a Charnockite Suite

open access: yesGeological Journal, Volume 61, Issue 3, Page 566-592, March 2026.
Charnockites with 2691–2607 Ma magmatic ages from the NMZ show arc‐magmatic geochemical signatures. They correspond to the lower‐crustal equivalent of the Chilimanzi Suite Granite in the Zimbabwe Craton. Lu‐Hf isotopic data of magmatic zircons show negative εHf(t) values (−11.18 to −2.20) with TDMC ages of 3699–3158 Ma, suggesting their protolith ...

A Targeted Approach for Mapping Groundwater Discharge to Surface Water and Fish Thermal Refuge in Four Lake Ontario Tributaries

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
Understanding groundwater discharge to surface water is crucial for ecosystems, water quality, and resource management. A flexible methodology was developed to first predict and then identify cold‐water zones and significant groundwater discharge areas in four key Lake Ontario tributaries.

Seasonal Dynamics of Riverine Inputs in Guadeloupe (French West Indies): Insights From More Than 12 Years of Monitoring

open access: yesHydrological Processes, Volume 40, Issue 3, March 2026.
Riverine solute fluxes peak during the wet season, emphasising the role of tropical rainfall in driving nutrient delivery to the ocean. Seasonal peaks in nutrient fluxes highlight the need for longer‐term monitoring to detect potential interannual trends.

Seismic Stratigraphy of Eocene–Recent Mixed Depositional Systems on the SE New Zealand Continental Margin, Great South Basin

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The continental margin of SE New Zealand is strongly influenced by the Southland Current and associated water masses. This new seismic stratigraphic study of the margin has revealed a range of depositional mounds and erosional channels that document the close interaction of turbidity and bottom currents in shaping the margin from the Mid‐Eocene onward.

Multiscale Analysis of Bouguer Gravity Anomalies: Unveiling the Deep Structure of Eastern Himalayan Syntaxis Faults

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The Eastern Himalayan Syntaxis (EHS), which is located at the southeastern edge of the Qinghai–Xizang Plateau, is a key region for understanding mountain‐building and subduction processes. Bouguer gravity anomalies derived from the Earth Gravitational Model 2008 free‐air anomaly data following topographic corrections, were analyzed.

High nitrogen fixation and Braarudosphaera presence in the North Sea

open access: yesLimnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Nitrogen fixation, the microbial conversion of dinitrogen gas to ammonia, is a key nitrogen source and critical for sustaining marine productivity. We investigated the diversity and activity of nitrogen‐fixers in surface waters of the North Sea and Norwegian coast during July 2023.
