Palaeoglacier reconstruction and dynamics of Cordillera Vilcanota in the tropical high Peruvian Andes

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.
We provide a geomorphological analysis of Cordillera Vilcanota and use morphostratigraphic principles to reconstruct palaeo icefield extent and palaeoglacier readvances, likely during the Antarctic Cold Reversal and Younger Dryas. We find evidence of temperate and polythermal ice margins, with limited glaciofluvial landform generation.

Giant pockmarks discovered on the West Greenland shelf

open access: yesArctic, Antarctic, and Alpine Research
Pockmarks provide valuable insights into subsurface fluid dynamics, methane release, and potential geohazards. We present the first detailed mapping and characterization of giant pockmarks (>250 m diameter) on the West Greenland continental shelf using ...

Seafloor mapping in the Arctic: support for a potential U.S. extended continental shelf [PDF]

open access: yes, 2010
For the United States, the greatest opportunity for an extended continental shelf under UNCLOS is in the ice-covered regions of the Arctic north of Alaska.

SURFACE TENSIONS: Roads, Potholes and the Embodied Politics of Driving in Urban India

open access: yesInternational Journal of Urban and Regional Research, Volume 50, Issue 1, Page 24-43, January 2026.
Abstract In this article I draw on the embodied experience of driving into potholes and on bumpy roads in Hyderabad to show how pockmarked roads become a terrain on which political sensibilities are shaped. Drawing on ethnographic material collected over six years, I analyze how potholes shape driving dispositions in a city that is attempting to brand ...

Combining morphological and molecular data to study past foraminiferal communities from a temperate coastal sediment core

open access: yesBoreas, Volume 55, Issue 1, Page 198-215, January 2026.
This paper presents the results of a dual approach for assessing fossil benthic foraminiferal communities using both traditional morphology‐based analyses and sedimentary ancient DNA (sedaDNA) metabarcoding. The main objectives are to test the feasibility of sedaDNA analyses to assess foraminiferal biodiversity in temperate shelf sediments (Le Croisic,

Protracted intercontinental aridification preserved within the early Late Cretaceous strata of the Eastern Gobi Basin, Mongolia

open access: yesSedimentology, Volume 73, Issue 1, Page 147-185, January 2026.
ABSTRACT Mongolia's Eastern and Western Gobi Basins preserve a globally significant record of Cretaceous terrestrial vertebrates, yet their biostratigraphic correlations are complicated by a complex geological history. The Eastern Gobi Basin, a northeast‐southwest trending fault‐bounded rift system, includes several minor sub‐basins with distinct ...

Fresh submarine groundwater discharge offshore Wellington (New Zealand): hydroacoustic characteristics and its influence on seafloor geomorphology

open access: yesFrontiers in Marine Science, 2023
Fresh submarine groundwater discharge (FSGD) influences the biogeochemistry of coastal areas and can be a proxy for potential untapped resources of offshore freshened groundwater (OFG).

Influence of Glaciological Structures on the Spatial Distribution of Cryoconite Holes, Northern Victoria Land, East Antarctica

open access: yesJournal of Geophysical Research: Earth Surface, Volume 130, Issue 12, December 2025.
Abstract Three blue‐ice areas in the upper reaches of Rennick Glacier, East Antarctica, are investigated using satellite remote sensing to assess the influence of meso‐ to large‐scale glaciological structures on cryoconite hole distributions. In total, 15,299 cryoconite holes and 1 600 structures were geospatially analyzed, which indicate that ...
