Monsoon and Glacial Meltwater Input Drive Seasonal Cooling of a Himalayan Ice‐Contact Lake

Water Resources Research, Volume 61, Issue 11, November 2025.
Abstract Thousands of glacial lakes exist across the Himalaya. However, the physical characteristics of these lakes that drive changes in glacier mass balance and meltwater delivery downstream are poorly understood. We measured water temperature with depth in Thulagi Lake, Nepal, between May and October 2023 to give the first observations of the ...

Wartanian glacial sediments: insights into deglaciation of Polish Lowlands and Highlands border for geotourism

Miscellanea Geographica: Regional Studies on Development
This paper presents five sites located in the marginal zone of the Wartanian stadial within the Odranian Glaciation (MIS6a) on the border of the Central Polish Uplands and Lowlands, representing different glacial forms and geological structures: terminal

Geomagnetic Secular Variation Models for Latitude Scaling of Cosmic Ray Flux and Considerations for ¹⁰Be Exposure Dating of Laurentide Ice Sheet Retreat

Quaternary
Published cosmogenic 10Be exposure ages from the terminal moraine of the Laurentide Ice Sheet (LIS) in northeastern North America have been interpreted to date the start of the retreat of the LIS at the Last Glacial Maximum (LGM) about 25 thousand years ...

Calving as a Source of Acute and Persistent Kinetic Energy to Enhance Submarine Melting of Tidewater Glaciers

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Calving icebergs at tidewater glaciers release large amounts of potential energy. This energy—in principle—could be a source for submarine melting, which scales with near‐terminus water temperature and velocity. Because near‐terminus currents are challenging to observe or predict, submarine melt remains a key uncertainty in projecting ...

Ancient sedimentary DNA shows more than 5000 years of continuous beaver occupancy in Grand Teton National Park

Ecosphere, Volume 16, Issue 10, October 2025.
Abstract Beaver‐based restoration is emerging as a cost‐effective conservation and climate adaptation strategy, but efforts are constrained by limited knowledge of pre‐colonial beaver distribution and their long‐term ecosystem impacts. Here, we apply sedimentary ancient DNA (sedaDNA) techniques to investigate the history of beaver occupancy at three ...

Multi‐Year Glaciological and Meteorological Observations on Debris‐Covered Kennicott Glacier, Alaska, 2016–2023

Geoscience Data Journal, Volume 12, Issue 4, October 2025.
A seven year record of multi‐variable field observations (meteorological, glaciological mass balance) is presented for Kennicott Glacier, a large debris‐covered glacier in the Wrangell Mountains Alaska. This dataset will be useful for calibrating remote sensed data, constraining energy and mass balance models, and pursuing targeted glaciological and ...

Spatial variations of Sr–Nd isotopic ratios, mineralogical and elemental compositions of cryoconite in an Alaskan glacier

Annals of Glaciology, 2018
To understand the geological origins of minerals in cryoconite and the nutrients sources for microbes on glaciers, we analyzed the Sr–Nd isotopic ratios of the four mineral fractions in cryoconites including saline, carbonate, phosphate, silicate and the

Role of Sparsely Glacierized Basins and Groundwater in Semiarid Andes Periglacial Headwaters

Hydrological Processes, Volume 39, Issue 10, October 2025.
This study highlights for the first time the role of the Andean low‐glacierized headwater basin in providing significant water flow to the outlet discharge (20%–30%) with relatively long residence times (several decades). It can be explained by unknown permafrost bodies, which must be better characterized to manage water in a changing climate in ...
