Revealing Permafrost Continuity Across a Northern Watershed With Airborne Electromagnetics

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract Permafrost thawing in northern regions may alter groundwater‐surface water dynamics, thereby impacting hydrologic and ecologic functions and the potential release of stored solutes including carbon. Here, we present an airborne frequency‐domain electromagnetic survey over a discontinuous permafrost region within the Central Mackenzie Valley in

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.

Hardness Toxicity and Multi‐Route, Multi‐Demographic Health Risks of Nitrate‐Contaminated Groundwater: A Call for Sustainable Environmental and Public Health Protection

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Groundwater contamination by nitrate and hardness poses critical challenges to environmental sustainability and public health across many regions. This research pioneers an integrated assessment of nitrate multi‐route exposure for six‐age groups and hardness toxicity in Ghana.

Magnetotelluric Exploration of Zn Pb Mineralization in Stonepark, Irish Midlands

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT To meet the increasing demand for raw materials and to foster the energy transition, advances in exploration techniques are required that extend capabilities to deeper and/or more densely populated areas while having a low environmental and societal impact.

Paleotemperature modeling of hydrocarbon generation centers and their role in the formation of «Paleozoic» oil deposits (Ostaninskoe field, Tomsk region)

Georesursy
Study and exploration of the pre-Jurassic oil and gas complex in Western Siberia is one of the aspects of hydrocarbon raw-material base development. The main scope of this study is to locate the source of Paleozoic hydrocarbons.

Deep Groundwater Total Dissolved Solids Mapping in the Dakota Group, Williston Basin, USA

Groundwater, Volume 64, Issue 3, Page 335-349, May/June 2026.
Abstract Growing concern about the quantity of available freshwater around the world has led to interest in surveying groundwater total dissolved solids (TDS) below water well depths. Deep TDS has not been systematically mapped, and there is much to learn about the distribution and controls on deeper groundwater. In sedimentary basins across the United

Nitrogen Stable Isotopes Track Ammonia Emission Sources and Ammonium Aerosol Formation Processes in the Marine Boundary Layer

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract We measured the nitrogen isotopic composition of surface seawater and aerosol ammonium in the Weddell Sea region of the Southern Ocean to investigate the natural atmospheric cycle of marine ammonia emissions and aerosol ammonium formation in a region not overwhelmed by anthropogenic emissions.
