Going Deeper With Deep Learning: Automatically Tracing Internal Reflection Horizons in Ice Sheets—Methodology and Benchmark Data Set

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 2, June 2025.
Abstract Mapping the internal stratigraphy of ice sheets serves a variety of glaciological applications, from the study of past ice flows to current distribution of surface mass balance and melting to contemporary ice dynamics, all of which are crucial for improving future projections of sea level rise.

Sea-level response to ice sheet evolution: An ocean perspective [PDF]

The ocean's influence upon and response to Antarctic ice sheet changes is considered in relation to sea level rise over recent and future decades. Assuming present day ice fronts are in approximate equilibrium, a preliminary budget for the ice sheet is ...

Seabed corrugations beneath an Antarctic ice shelf revealed by autonomous underwater vehicle survey: Origin and implications for the history of Pine Island Glacier [PDF]

, 2013
Ice shelves are critical features in the debate about West Antarctic ice sheet change and sea level rise, both because they limit ice discharge and because they are sensitive to change in the surrounding ocean.

Discovery of the William's Ridge and Rig Seismic Seamount Microcontinents, Kerguelen Plateau: Signatures of a Fragmented Rifted Margin

Tectonics, Volume 44, Issue 6, June 2025.
Abstract The Kerguelen large igneous province (LIP), situated dominantly in the southern Indian Ocean, has several exceptional characteristics. These include an episodic and protracted formation over a ∼130 Myr period, sustaining the longest, continuous high‐magma‐flux emplacement interval of any LIP (>38 Myr), and the preservation of multiple ...

Sea-Ice Production in Antarctic Coastal Polynyas Estimated From AMSR2 Data and Its Validation Using AMSR-E and SSM/I-SSMIS Data [PDF]

, 2017
Antarctic coastal polynyas are very high sea-ice production areas. The resultant large amount of brine rejection leads to the formation of dense water.

Modelling iceberg capsize in the open ocean [PDF]

arXiv, 2020
At near-grounded glacier termini, calving can lead to the capsize of kilometer-scale unstable icebergs. The transient contact force applied by the capsizing iceberg on the glacier front generates seismic waves that propagate over teleseismic distances. The inversion of this seismic signal is of great interest to get insight into actual and past capsize

Public Health Microbiome Curriculum: Looking Below the Tip of the Iceberg for Approaches to Population Health

Microbial Biotechnology, Volume 18, Issue 6, June 2025.
Current public health messages represent the ‘tip of the iceberg’. We describe three public health microbiome curriculum modules on breastfeeding, antibiotics and diet that examine how upstream factors affect the microbiome and influence health across the life course.

Surface wave generation due to glacier calving

Oceanologia, 2013
Coastal glaciers reach the ocean in a spectacular process called "calving". Immediately after calving, the impulsive surface waves are generated, sometimes of large height.

Calving dynamics at Jakobshavn Isbrae (Sermeq Kujalleq) controlled by local geometry: insights from a 3D Stokes calving model

Journal of Glaciology
We present the first simulations of Jakobshavn Isbrae (Sermeq Kujalleq), west Greenland, using a 3D Stokes calving model that permits unrestricted advance and retreat.

Calving Fronts of Antarctica: Mapping and Classification

Remote Sensing, 2013
Antarctica is surrounded by a variety of large, medium and small sized ice shelves, glacier tongues and coastal areas without offshore floating ice masses. We used the mosaic of the Radarsat-1 Antarctica Mapping Project (RAMP) Antarctic Mapping Mission 1
