Mechanisms of Surface Meltwater Ponding and Drainage on the Greenland Ice Sheet Revealed Using SkySat Imagery and Deep Learning

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Surface meltwater impacts Greenland Ice Sheet mass balance indirectly by reducing albedo and promoting hydrofracture. However, fully understanding both processes requires accurate mapping of small‐scale features such as ponds, channels, and moulins that govern meltwater formation and drainage. Here we investigate surface water dynamics at high

The role of subtemperate slip in thermally driven ice stream margin migration [PDF]

, 2018
The amount of ice discharged by an ice stream depends on its width, and the widths of unconfined ice streams such as the Siple Coast ice streams in West Antarctica have been observed to evolve on decadal to centennial timescales.

The Development of a Low Power GNSS System, as Part of a Drone Assisted Environmental Sensor Network for a Glacial Environment

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract We show the development of an innovative Internet of Things Real Time Kinematic Global Navigation Satellite System, to study the short‐term changes in surface velocity of two adjacent Icelandic glaciers, in order to understand the response of glaciers to climate change.

Drivers of Benthic Iron Fluxes and the Pore‐Water Iron Isotopic Signature in Surface Sediments of South Georgia Fjords, Sub‐Antarctica

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Benthic iron (Fe) fluxes from coastal sediments support phytoplankton blooms downstream of subpolar islands. We combine solid‐phase and pore‐water geochemical data, including its iron isotopic signature (δ56Feaq), to identify the main drivers of benthic Fe fluxes from sub‐Antarctic fjord and shelf sediments of South Georgia, and to evaluate ...

Emergence of the Shackleton Range from beneath the Antarctic Ice Sheet due to glacial erosion [PDF]

, 2014
This paper explores the long-term evolution of a subglacial fjord landscape in the Shackleton Range, Antarctica. We propose that prolonged ice-sheet erosion across a passive continental margin caused troughs to deepen and lower the surrounding ice-sheet ...

Iron and Manganese Cycling in the Atlantifying Barents Sea: Concentrated Inputs and Emerging Limitations

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Dissolved iron (dFe) and manganese (dMn) are essential micronutrients required in marine primary production; however, their low availability limits productivity and impacts the efficiency of the biological carbon pump. Therefore, it is crucial to elucidate their sources, sinks, and internal cycling.

Extremely low long‐term erosion rates around the Gamburtsev Mountains in interior East Antarctica [PDF]

, 2010
The high elevation and rugged relief (>3 km) of the Gamburtsev Subglacial Mountains (GSM) have long been considered enigmatic. Orogenesis normally occurs near plate boundaries, not cratonic interiors, and large‐scale tectonic activity last occurred in ...

Mantle Dynamic Topography of the Fringing Oceanic Basins of Antarctica

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Dynamic mantle processes are known to influence oceanic basins with implications for ocean circulation and climate. This study exploits an interdisciplinary approach to probe present‐day mantle and lithosphere beneath Antarctica's fringing oceanic basins to better understand sub‐crustal processes and implications for the continental realm.

Analysis of long-term dynamic changes of subglacial lakes in the Recovery Ice Stream, Antarctica [PDF]

The Cryosphere
The dynamic activity of subglacial lakes plays a crucial role in modulating glacial processes and the mass balance of the Antarctic ice sheet. The Recovery Ice Stream (RIS), projected to experience significant mass loss in East Antarctica during coming ...
