Hidden subsurface suspended sediment export from Greenland's marine‐terminating glaciers

Limnology and Oceanography Letters, Volume 11, Issue 6, November 2026.
Abstract Runoff and calved ice volumes from the Greenland Ice Sheet are well constrained, but quantifying the associated suspended sediment flux remains challenging. Here we present near‐terminus observations from three glacierized fjords in southeast Greenland, combining full‐depth turbidity profiles and current velocity from summer 2024 to evaluate ...

Macrofauna Associated With Submarine Groundwater Discharge Sites and a Cold Seep in Svalbard Fjords

Ecology and Evolution, Volume 16, Issue 10, October 2026.
This conceptual model illustrates how the balance between submarine groundwater discharge (SGD), glacimarine sedimentation, and benthic community development may change during glacier retreat in Arctic fjords. In present‐day marine‐terminating systems, high sedimentation and physical disturbance may mask the ecological effects of SGD.

Geochronological reconstruction of the Lateglacial deglaciation in the Arve Valley (Northern French Alps)

Journal of Quaternary Science, Volume 41, Issue 7, Page 1020-1035, October 2026.
ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a

Refinement of the Quaternary seismic stratigraphy and analysis of buried glacial channels on the Labrador Shelf

Journal of Quaternary Science, Volume 41, Issue 7, Page 1141-1158, October 2026.
ABSTRACT The Laurentide Ice Sheet covered vast areas of North America during the Wisconsinan, including the Labrador Shelf, off the coast of eastern Canada. The shelf is characterized by glacial cross‐shelf troughs, which have been considered as predominantly eroded by the last ice advance.

Hydraulic impacts of glacier advance over a sediment bed [PDF]

, 2006
A sedimentary sequence of till overlying a gravel aquifer was instrumented with water-pressure transducers prior to a small, anticipated surge of the margin of the glacier Breiðamerkurjökull in Iceland.

The Causes and Implications of Microstructures in Glacial Sediments [PDF]

, 1998
This thesis examines how microstructures in glaciogenic sediments reflect the processes forming them, and how these microstructures then affect the conditions around them, through a series of field studies, laboratory tests, models, and statistical ...

Depositional and Hydrological Relationships Between Buried Dead Ice and the Active Layer in the McMurdo Dry Valleys, Antarctica: A Study of Sediment Geochemistry and Cation Concentrations

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 725-752, October/December 2026.
ABSTRACT The McMurdo Dry Valleys, the largest ice‐free region in Antarctica, are home to a cold‐desert hydrologic system of glaciers, snowbanks, streams, and lakes. Freshwater is also stored as dead glacial ice, which is poorly constrained in terms of ion concentrations and interactions with both in situ and overlying sediments.

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 ...

Hydrological controls on diurnal ice flow variability in valley glaciers [PDF]

, 2005
This paper uses a combination of field data and three-dimensional modeling to investigate the spatial variability in basal conditions required to induce observed fluctuations in diurnal ice velocity at Haut Glacier d'Arolla, Switzerland.

Crack wave resonances within the basal water layer

Annals of Glaciology, 2019
Hydraulic processes within and beneath glacial bodies exert a far-reaching control on ice flow through their influence on basal sliding. Within the subglacial system, rapid changes in these processes may excite resonances whose interpretation requires an
