Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 645-667, October/December 2026.
ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...

Offshore Groundwater Salinization and Flushing in the Canterbury Bight During Glacial‐Interglacial Cycles

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Offshore freshened groundwater (OFG) is a significant yet underexplored component of global water resources, occurring widely along many continental margins. However, its dynamics remain poorly constrained due to limited offshore observations and the absence of robust evaluation models for unambiguous emplacement interpretation.

Influence of Orbital Forcing on the Snowball Earth Deglaciation

Geophysical Research Letters
Neoproterozoic snowball Earth events lasted for multiple million years, experiencing many orbital cycles. Here we investigate whether the deglaciation of these events would be triggered more easily at certain orbital configurations than others, by using ...

Frequency‐Domain Airborne Electromagnetic Imaging of Permafrost Reveals Heterogeneity and Drivers of Permafrost Change in the Discontinuous Permafrost Zone of Northwestern Canada

AGU Advances, Volume 7, Issue 7, October 2026.
Abstract Northern permafrost landscapes are undergoing rapid warming and thaw, yet the three‐dimensional subsurface structure that governs thaw vulnerability and landscape response remains poorly resolved by conventional ground temperature monitoring and satellite remote sensing.

Influence of Floodplain Subsurface Composition on Peatland Stream Channel Mobility

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Peatlands are important for the earth's carbon cycle, globally storing the equivalent of two‐thirds of the atmospheric carbon reservoir. The capacity of peatlands to preserve organic matter is influenced by stream‐channel mobility and sediment reworking; however, the nature of these processes is poorly constrained.

Sea Surface Conditions and Antarctic Bottom Water Formation Offshore Cape Darnley, East Antarctica, Over the Last 600 ka: New Insights From the Diatom Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract The Cape Darnley marine region of East Antarctica is one of only four sectors where Antarctic Bottom Water (AABW) is produced. AABW formation at Cape Darnley is highly dependent on surface ocean processes—specifically, the high production of frazil ice. Here, we investigated the sea surface conditions at Cape Darnley over the past 600 thousand

On the Fidelity of Oxygen Isotope‐Based Sea Level Reconstructions: A Case Study of Marine Isotope Stage 3

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract Although foraminiferal oxygen isotope records (δ18OF) have long been used to develop time‐continuous estimates of past global ice volume, growing evidence indicates that the ice volume and temperature contributions to δ18OF diverge considerably over the last glacial cycle.

Transition of Glacial Regimes Recorded at IODP Site U1524 in the Ross Sea, Antarctica, Over the Last 800 Thousand Years

Paleoceanography and Paleoclimatology, Volume 41, Issue 10, October 2026.
Abstract Reconstructing past interactions between the West Antarctic Ice Sheet (WAIS) and changing environmental conditions in the Ross Sea region can help determine long‐term WAIS stability. Existing sedimentary records reveal changes to oceanography, sea ice and ice sheet extent over the glacial‐interglacial cycles of the last ∼800 kyr.

Deglaciation in an area on west Greenland : A Geomorphological studie

, 2011
The aim of this report is to describe the deglaciation in an area on west Greenland in the vicinity of Kangerlussuaq. To do this, the geomorphological landforms were mapped by studying areal photographs and by a two week field study where key areas were ...

Bat community assembly in the ecotone of two neotropical biodiversity hotspots is determined by environmental filtering rather than historical factors

Journal of Animal Ecology, Volume 95, Issue 10, Page 2050-2062, October 2026.
We demonstrate that environmental filtering is the primary mechanism shaping bat communities across the Cerrado–Atlantic Forest ecotone. By integrating phylogenetic diversity, environmental gradients, and coevolutionary assembly models, our study provides new insights into the processes maintaining biodiversity in a globally important transition zone ...
