Evaluating Testability of Permafrost Models Through Physical and Thermal Testing in Complex Mountain Terrain, Yukon, Canada

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 570-591, October/December 2026.
ABSTRACT Due to its subsurface nature, permafrost cannot be directly observed with the naked eye or optical remote sensing. Consequently, accurately describing its distribution and thermal state is challenging. This is especially true in vast, remote environments, where obtaining comprehensive field data is demanding or improbable.

Depositional and Hydrological Relationships Between Buried Dead Ice and the Active Layer in the McMurdo Dry Valleys, Antarctica: A Study of Sediment Geochemistry and Cation Concentrations

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 725-752, October/December 2026.
ABSTRACT The McMurdo Dry Valleys, the largest ice‐free region in Antarctica, are home to a cold‐desert hydrologic system of glaciers, snowbanks, streams, and lakes. Freshwater is also stored as dead glacial ice, which is poorly constrained in terms of ion concentrations and interactions with both in situ and overlying sediments.

Quantifying the Surface Deformation of Pingos on the Alaskan North Slope Using Interferometric Synthetic Aperture Radar (InSAR)

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 682-691, October/December 2026.
ABSTRACT Pingos are large mounds with cores formed of intrusive ice that form in periglacial landscapes. These ice structures can form in regions of discontinuous permafrost, commonly as hydraulic or open‐system pingos, or in locations of continuous permafrost, commonly as hydrostatic or closed‐system pingos.

Carbon Nanorods With Adhered Monodisperse Cobalt Nanoparticles Exhibiting Electromagnetic Wave Absorption and Antibacterial Potential

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Magnetic particles coated with carbon shells have been considered as promising electromagnetic wave absorption materials with antibacterial features. However, how to precisely control the monodispersed magnetic nanoparticles on a carbon matrix to manipulate impedance matching and antibacterial performances is still a key challenge.

Tuvaijuittuq: The Last Refuge of Multiyear Ice (MYI) Is Becoming Increasingly Open

Journal of Geophysical Research: Oceans, Volume 131, Issue 10, October 2026.
Abstract Tuvaijuittuq is currently the largest in a series of Marine Protected Areas (MPAs) in the Canadian Arctic. The remoteness, inaccessibility and paucity of environmental data creates challenges in understanding and establishing conservation management strategies of this unique multiyear ice (MYI)‐dominated region.
