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

Earth 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.

Asynchronous glacier dynamics during the Antarctic Cold Reversal in central Patagonia [PDF]

, 2018
We present 14 new 10Be cosmogenic nuclide exposure ages quantifying asynchronous readvances during the Antarctic Cold Reversal from glaciers in the Baker Valley region of central Patagonia.

DeepRec: Global Terrestrial Water Storage Reconstruction Since 1941 Using Spatiotemporal‐Aware Deep Learning Model

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.
Abstract Terrestrial water storage (TWS) plays an important role in describing the Earth system, as water availability is decisive for ecosystems and human development. Since 2002, the Gravity Recovery and Climate Experiment (GRACE) and its Follow‐On (GRACE‐FO) mission have measured TWS anomalies with unprecedented accuracy, enabling a leap in ...

The Hydroclimate of the Ottawa River Basin Under Climate Change

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 1, February 2026.
ABSTRACT The freshwater resource of the Ottawa River basin (ORB) is vital for ecological services and economic activities in the region. With climate change impacts becoming more evident, sustainable management is imperative. As a first step, it is important to assess impacts on hydro‐climatology.

Update of annual calving front lines for 47 marine terminating outlet glaciers in Greenland (1999–2018)

Geological Survey of Denmark and Greenland Bulletin, 2019
The Greenland ice sheet has been losing mass in response to increased surface melting (Khan et al. 2015; van den Broeke et al. 2017) as well as discharge of ice from marine terminating outlet glaciers (van den Broeke et al. 2009; Box et al. 2018). Marine

Calibrating calving parameterizations using graph neural network emulators: application to Helheim Glacier, East Greenland [PDF]

The Cryosphere
Calving is responsible for the retreat, acceleration, and thinning of numerous tidewater glaciers in Greenland. An accurate representation of this process in ice sheet numerical models is critical to better predict the future response of the ice sheet to

Implications of Realistic Antarctic Ice Shelf Basal Melting During 2006–2016 on Southern Ocean Climate

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract We investigate implications of the recent change in basal melt rates from 93 Antarctic ice shelves from the 1990s to 2006–2016 (223 Gt yr−1 on average) on Southern Ocean climate using a fully coupled model. The most prominent response is significant increased sea ice coverage in the northern Amundsen Sea and decreased sea ice coverage in the ...

Tides modulate crevasse opening prior to a major calving event at Bowdoin Glacier, Northwest Greenland

Journal of Glaciology, 2020
Retreat of calving glaciers worldwide has contributed substantially to sea-level rise in recent decades. Mass loss by calving contributes significantly to the uncertainty of sea-level rise projections.

Mycobacteriophage Mcgavigan Uses Noncanonical Bxb1‐Like Repressor for Heterotypic Superinfection Immunity

Journal of Basic Microbiology, Volume 66, Issue 1, January 2026.
ABSTRACT Mycobacteriophage Mcgavigan could be a promising candidate for use as a preventative agent against infections with Mycobacterium avium subsp. paratuberculosis. Bioinformatic analysis of the Mcgavigan genome revealed the presence of an operon containing a “Bxb1‐like” repressor.
