Research progress in geophysical exploration of the Antarctic ice sheet

Earthquake Research Advances, 2023
The Antarctic ice sheet is an important target of Antarctic research. Thickness and structure, including intraice and subice, are closely related to the mass balance of the ice sheet, and play an important role in the study of global sea level and ...

The sedimentary legacy of a palaeo-ice stream on the shelf of the southern Bellingshausen Sea: Clues to West Antarctic glacial history during the Late Quaternary [PDF]

, 2010
A major trough ("Belgica Trough") eroded by a palaeo-ice stream crosses the continental shelf of the southern Bellingshausen Sea (West Antarctica) and is associated with a trough mouth fan ("Belgica TMF") on the adjacent continental slope.

Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel

Advanced Functional Materials, EarlyView.
This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create

Proglacial Lake Drainage Events Drive Fast Grounding Line Advance in a Warming Climate

Geophysical Research Letters
Proglacial lakes along the retreating margin of the Laurentide ice sheet (LIS) significantly influenced the ice sheet's dynamics. This study investigates the interaction between proglacial lake drainage events and ice sheet evolution during deglaciation.

Peridynamic Simulation of the Penetration of an Ice Sheet by a Vertically Ascending Cylinder

Journal of Marine Science and Engineering
The vertical ice breaking of marine structures in ice-covered areas involves the deformation and failure of an ice sheet. Different from the existing conventional scenarios where the ice sheet is used as a transportation and support medium, the damage to

Rapid Basal Channel Growth Beneath Greenland's Longest Floating Ice Shelf

Geophysical Research Letters, 2023
Nioghalvfjerdsfjorden Glacier (N79) is one of the two main outlets for Greenland's largest ice stream, the Northeast Greenland Ice Stream, and is the more stable of the two, with no calving front retreat expected in the near future. Using a novel surface

An assessment of key model parametric uncertainties in projections of Greenland Ice Sheet behavior [PDF]

, 2012
Lack of knowledge about the values of ice sheet model input parameters introduces substantial uncertainty into projections of Greenland Ice Sheet contributions to future sea level rise.

Investigating the impact of sub-ice shelf melt on Antarctic ice sheet spin-up and projections [PDF]

The Cryosphere
Sub-ice shelf melting is critical for the stability of the Antarctic ice sheet, as it influences ice-shelf buttressing that reduces grounded ice flow. Previous studies have emphasized that uncertainties in the state of sub-ice shelf melting contribute to

Residual‐Lithium‐to‐LiF Conversion Enables a LiF–Fluorinated Carbon Interphase for Reconstruction‐Resistant Ni‐Rich Cathodes

Advanced Functional Materials, EarlyView.
A fluorine‐rich acrylate monomer (PFHEA) was solvent‐free applied to NCM90 and thermally decomposed under Ar to convert residual lithium into LiF and form a pre‐built LiF/fluorinated amorphous carbon (LiF/FC) interphase. The LiF/FC layer suppresses NiO rock‐salt reconstruction and microcrack propagation, lowers interfacial resistance, and improves Li ...
