Learning to melt: Emulating Greenland surface melt from a polar RCM with machine learning [PDF]

The Cryosphere
Predicting surface melt on the Greenland ice sheet is critical for understanding surface mass balance (SMB) and its sensitivity to a changing climate. Polar regional climate models (RCMs) are the primary tools for simulating melt and projecting future ...

Triple Oxygen Isotope Compositions of Isotopic Reference Waters: Implications for VSMOW‐Scale and VSMOW–SLAP‐Scale Δ′17O Calibration

Geostandards and Geoanalytical Research, EarlyView.
Key Points Triple oxygen isotope ratios of two primary (VSMOW, SLAP) and twelve secondary water isotopic reference materials were precisely measured using BrF5 fluorination‐IRMS. The measured Δ'17OVSMOW value for SLAP (34 ± 6 per meg) demonstrates that VSMOW‐SLAP normalisation ensures interlaboratory comparability, but introduces systematic offsets for

The layering of polar firn - investigations of the climatic impact on polar firn structure using high resolution density measurements and 3D-X-ray-microfocus-computer-tomography [PDF]

, 2010
The polar firn structure is investigated in terms of layering using high-resolution density measurements of 19 firn cores and X-ray-microfocus-computer-tomography image analysis of 6 surface firn cores. The impact of local climate conditions such as mean

Passive Radar Sounding for Firn Aquifer Monitoring

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Firn aquifers may play an important role in the mass balance of the Greenland ice sheet, but changes in their water storage are challenging to measure due to their spatiotemporal variability.

A Causal Examination of the Solar Influence on Holocene Climate

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Variations in Total Solar Irradiance (TSI) have long been hypothesized to influence global mean surface temperature (GMST) on multidecadal to millennial timescales, but empirical evidence has remained elusive. Here, we explore the link between solar variability and climate over the pre‐industrial Holocene, when anthropogenic influences were ...

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

Challenges in modeling the energy balance and melt in the percolation zone of the Greenland ice sheet

Journal of Glaciology, 2023
Increased surface melt in the percolation zone of the Greenland ice sheet causes significant changes in the firn structure, directly affecting the amount and timing of meltwater runoff.

Atmospheric River‐Cyclone Events Disrupting an Antarctic Peninsula Field Campaign: Dynamics, Mesoscale Wind Amplification, and Long‐Term Context

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 16, 28 August 2026.
Abstract Extreme weather in the Antarctic Peninsula arises from interactions among large‐scale circulation variability, atmospheric rivers (ARs), extratropical cyclones, and complex coastal terrain, yet the linkages across these scales remain insufficiently resolved.

Satellite Mapping of the Moulin Distribution Across the Entire Greenland Ice Sheet

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Moulins drain meltwater from the surface of the Greenland Ice Sheet (GrIS), affecting subglacial hydrology. However, the moulin distribution across the entire GrIS remains unclear. Using 10‐m Sentinel‐2 imagery from the summer of 2019, we manually mapped GrIS‐wide major moulins, excluding undetectable minor moulins.
