Elucidating the Reactivity and Fate of Dissolved Organic Matter in Groundwater Entering the Alaska Beaufort Sea Coast Using 14C Ramped Oxidation

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Supra‐permafrost groundwater (SPGW) is a significant but understudied source of dissolved organic matter (DOM) to Arctic coastal systems. We applied ramped pyrolysis/oxidation (RPO) with Δ14C and δ13C isotopic analysis to assess DOM reactivity and origin in SPGW, river, and lagoon waters along the Alaska Beaufort Sea coast.

Glacial refugia, postglacial dynamics, and hybrid zones of Pinaceae in Eurasia captured from sedimentary ancient DNA

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Boreal forests cover nearly one‐third of global forest area. Glacial cycles have shaped the distribution and connectivity of modern Pinaceae genera, yet species‐level refugia, postglacial migrations, and hybridization patterns remain unclear due to limited high‐resolution taxonomic and temporal data. We applied a hybridization capture approach

Quantification of ground surface movements on sorted circles using time‐lapse structure‐from‐motion photogrammetry in a karst cave, Slovenia

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
We present ground surface movements on sorted circles in a karst cave using time‐lapse photogrammetry with accuracies of up to ±2 mm. Data with 3‐hourly resolution revealed average vertical movements of up to 50 mm and horizontal movements of up to 15 mm during individual freeze–thaw cycles.

Loess Studies in Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Low Hazard–High Risk: A Case Study of the Active Mangatangi Fault

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Activity on low deformation rate faults are challenging to quantify and comparatively understudied. One such fault, the Mangatangi Fault, strikes NE‐SW along the southeastern flanks of the Hunua Ranges c. 52 km south of New Zealand's most populous city, Auckland.
