Seasonal variations in proglacial lake area revealed by high spatial resolution planetscope satellite imagery

Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.
High‐resolution PlanetScope imagery reveals seasonal variations in proglacial lake area are underestimated by ~7% in moderate‐resolution data, while use of a single summer image can underestimate annual maximum area by ~2%. Capturing these seasonal variations provides valuable insights into the factors driving lake dynamics at Fjallsárlón, Iceland ...

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

Water Resources Research
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.

A low‐cost, automated, and adaptable system for field‐based measurement of pCO2, pCH4, and associated variables in groundwater

Limnology and Oceanography: Methods, Volume 24, Issue 2, February 2026.
Abstract The Groundwater Automated Chemical Examiner (GrACE) is an automated analytical system of integrated sensors for the field‐based measurement of chemical and physical properties of groundwater. The GrACE system was designed to explore parameters influencing the dissolved concentrations of carbon dioxide (pCO2) and methane (pCH4) in groundwater ...

From Collision to Subduction: Thermal‐Kinematic Inversions Constrain Plate Boundary Structure and Dip‐Slip Activity in Southwestern New Zealand

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Constraints on three‐dimensional fault system geometry and kinematics are required to understand both long‐term tectonics and contemporary seismic hazard. In many cases, these parameters must be inferred from a combination of different data or analyses.

The length of the world’s glaciers – a new approach for the global calculation of center lines [PDF]

, 2014
Glacier length is an important measure of glacier geometry. Nevertheless, global glacier inventories are mostly lacking length data. Only recently semi-automated approaches to measure glacier length have been developed and applied regionally.

Subglacial Topography of Coats Land Records Post‐Gondwanan Landscape Evolution and Early Ice‐Sheet Behavior in East Antarctica

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The East Antarctic Ice Sheet (EAIS) formed circa 34 million years ago and now contains an ice volume equivalent to ∼52 m of global sea‐level rise. Although the EAIS is approximately in balance today, there is substantial uncertainty regarding the sensitivity of sectors underlain by low‐lying bed topography to future climate and ocean warming ...

Six Decades (1958–2018) of Geodetic Glacier Mass Balance in Monte San Lorenzo, Patagonian Andes

Frontiers in Earth Science, 2019
A full understanding of glacier changes in the Patagonian Andes over decadal to century time-scales is presently limited by a lack of detailed and appropriate long-term observations.

A last glacial ice sheet on the Pacific Russian coast and catastrophic change arising from coupled ice–volcanic interaction [PDF]

, 2008
Controversy exists over the extent of glaciation in Eastern Asia at the Last Glacial Maximum: complete ice sheet cover vs. restricted mountain icefields (an area discrepancy equivalent to 3.7 Greenland Ice Sheets).

Increased Glacier Melt Across Millennia to Hours Enhances Erosion and Sediment Export Processes

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract Glacial erosion and sediment evacuation are key in shaping polar and mountain landscapes and influencing downstream ecological and social systems. The glacier dynamics and hydrology responsible for these processes are closely linked to hydrological and climatic (hydro‐climatic) conditions.

Subglacial hydrology at Rink Isbræ, West Greenland inferred from sediment plume appearance

Annals of Glaciology, 2016
Marine-terminating outlet glaciers discharge most of the Greenland ice sheet's mass through frontal ablation and meltwater runoff. While calving can be estimated by in situ and remote sensing observations, submarine melting and subglacial meltwater ...
