Aircraft Ionizing Radiation Exposure for Solar Cycle 24/25 From ARMAS and NAIRAS

Space Weather, Volume 24, Issue 7, July 2026.
Abstract Exposure to ionizing radiation from galactic cosmic rays and solar energetic particles at aviation flight altitudes can have an adverse effect on human health. Although airline crews are classified as radiation workers by the International Commission on Radiological Protection (ICRP), in most countries, their level of exposure is unquantified ...

Quantifying the Role of Karst Groundwater on Mountain River Discharge

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract In snow‐fed, mountainous karst regions, aquifers sustain and are connected to streamflow via springs and distributed groundwater exchanges (DGE) including inflows (DGI) and losses (DGL). Despite their significance, there is limited understanding of the complex flow paths linking aquifers and streams, particularly regarding flow path source and

Low Chemical Weathering Intensity, Enhanced Erosion, and Euxinic Conditions Along the Norwegian Margin During the Paleocene‐Eocene Thermal Maximum

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract The Paleocene–Eocene Thermal Maximum (PETM; ∼55.9 Ma) was a rapid global warming event marked by intensified hydrological cycling, enhanced continental weathering, and widespread ocean deoxygenation. Although the extent of anoxic basins during the PETM is relatively well documented, the contribution of high‐latitude continental weathering to ...

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

Boreas, Volume 55, Issue 3, Page 768-789, July 2026.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

Luminescence dating of coastal deposits from the Chanthaburi Plain, Thailand

Boreas, Volume 55, Issue 3, Page 846-865, July 2026.
The ongoing global sea‐level rise urges us to better understand the dynamics of coastal processes for predicting future changes. Sedimentary deposits reflect past coastal environments but require precise chronological data to place evidence into a temporal context.

Longevity and Reactivation of Intracontinental Walled Basins: Thermochronologic Evidence From Western Mongolia

Basin Research, Volume 38, Issue 4, July–August 2026.
Permian–Jurassic tectonism produced cooling ages preserved in Mesozoic strata of the Dzereg and Dariv basins. Thermal modeling indicates mid‐Cretaceous and late Cenozoic basin inversion and cooling synchronous with bounding‐range exhumation, supporting a long‐lived source‐to‐sink relationship and persistent inherited relief since the Jurassic ...
