Drivers of Dissolved Thorium Isotope Distributions Along the Adélie Land Margin, East Antarctica: The Roles of Reversible Scavenging, Conservative Transport, and Lithogenic Supply

Global Biogeochemical Cycles, Volume 40, Issue 9, September 2026.
Abstract In this study, we present a mix of full‐depth profiles and near‐bottom observations of dissolved 230Th and 232Th from the Adélie Land margin in East Antarctica, a key site of Antarctic Bottom Water (AABW) formation. We show that the distribution of dissolved Th isotopes in this region is governed by a combination of reversible scavenging ...

Distinct Groundwater Regimes in West Antarctic Sedimentary Basins Inferred From Magnetotelluric Imaging

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Subglacial sedimentary basins in Antarctica are hypothesized to modulate ice flow and biogeochemical cycles via groundwater and geothermal feedbacks, yet their properties remain poorly constrained. Here, we present a joint quantitative analysis of new magnetotelluric (MT) data acquired at Thwaites Glacier (TG) and WAIS Divide, alongside legacy

The "tipping" temperature within Subglacial Lake Ellsworth, West Antarctica and its implications for lake access. [PDF]

, 2011
We present results from new geophysical data allowing modelling of the water flow within Subglacial Lake Ellsworth (SLE), West Antarctica. Our simulations indicate that this lake has a novel temperature distribution due to significantly thinner ice than ...

Recent aeromagnetic and deep electromagnetic exploration projects in East Antarctica

, 2006
Airborne geophysical surveys play a pivotal role in imaging subglacial geology and characterizing broad areas of the Antarctic liothsphere. Ground-based geophysics, coupled with airborne geophysics and geology, is essential to further elucidate crustal ...

Internal Structure and Formation Process of a Giant East Antarctic Grounding‐Zone Wedge

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The marine‐based portions of the East Antarctic Ice Sheet are currently losing mass at an accelerating rate due to atmospheric and oceanic forcing. Assessing these changes requires understanding long‐term grounding‐zone dynamics preserved in glacial geomorphology, including understudied East Antarctic shelf sectors.

Subglacial drainage processes at a High Arctic polythermal valley glacier [PDF]

, 2005
Dye-tracer experiments undertaken over two summer melt seasons at polythermal John Evans Glacier, Ellesmere Island, Canada, were designed to investigate the character of the subglacial drainage system and its evolution over a melt season. In both summers,

Exploring Antarctic Feedback Mechanisms Using Two‐Way Coupled Subglacial Hydrology and Ice Flow Modeling in the Siple Coast

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The Siple Coast region of West Antarctica is known for its fast flowing, topographically unconstrained ice streams that evolve due to subglacial conditions. In this work, we analyze the nature of the Siple Coast subglacial hydrologic system and its interactions with the ice sheet using two‐way coupled subglacial hydrology and ice flow modeling.
