Measurements of Ice Shelf Water beneath the front of the Ross Ice Shelf using gliders

Annals of Glaciology, 2017
Measurements made by an underwater glider deployed near the Ross Ice Shelf were used to identify the presence of Ice Shelf Water (ISW), which is defined as seawater with its potential temperature lower than its surface freezing point temperature ...

Simulating ice-shelf extent using damage mechanics

Journal of Glaciology, 2022
Inaccurate representations of iceberg calving from ice shelves are a large source of uncertainty in mass-loss projections from the Antarctic ice sheet. Here, we address this limitation by implementing and testing a continuum damage-mechanics model in a ...

Molecular Engineering Mediated Interfacial Assembly as an Artificial Extracellular Matrix Remolds Bacteria With Enhanced Abiotic Resilience

Advanced Science, EarlyView.
A biomimetic artificial extracellular matrix is assembled directly on Pseudomonas fluorescens by co‐assembling amyloid‐like lysozyme and alginate at the cell surface. This conformal nanocoating acts as both a hydration buffer and a physiological priming layer, markedly enhancing desiccation tolerance, seed adhesion, storage stability, and biocontrol ...

Actively evolving subglacial conduits and eskers initiate ice shelf channels at an Antarctic grounding line

Nature Communications, 2017
The formation mechanisms of ice-shelf channels remain poorly understood. Here, using ice-penetrating radar data, the authors propose that ice-shelf channel morphology in the Roi Baudouin Ice Shelf, East Antarctica, is seeded by esker ridges, indenting ...

Frazil ice formation in an ice shelf water plume [PDF]

Journal of Geophysical Research: Oceans, 2004
We present a model for the growth of frazil ice crystals and their accumulation as marine ice at the base of Antarctic ice shelves. The model describes the flow of buoyant water upward along the ice shelf base and includes the differential growth of a range of crystal sizes.

Ice Shelf Water Structure Beneath the Larsen C Ice Shelf in Antarctica

Geophysical Research Letters, 2023
AbstractUnderstanding ice shelf water (ISW) structure is crucial for studying the basal melting of ice shelves. In this study, we performed large‐eddy simulation experiments to assess ISW structure and basal melt patterns under different current velocity scenarios observed in the Larsen C ice shelf, Antarctica.

Does a Specialized Niche Market Vegetable Processor Enjoy Bargaining Power?

Agribusiness, EarlyView.
ABSTRACT Agribusiness companies may achieve competitive advantage through specialization within niche markets. One such niche is the fresh‐cut fruit and vegetable market, which has been steadily growing in Germany. This study examines whether the specialization of a German fresh‐cut producer grants it with market power within this niche market.

Accelerating Biosensor Discovery: A Computationally‐Driven Pipeline for Microplastics Monitoring

Advanced Intelligent Discovery, EarlyView.
A computationally guided pipeline unites molecular simulation, synthetic biology, electrochemical engineering, and machine learning to accelerate biosensor discovery. A Bacillus anthracis carbohydrate‐binding module is used to develop a high‐performance micro‐ and nanoplastics sensor with greatly reduced error and variability.

Ocean wave blocking by periodic surface rolls fortifies Arctic ice shelves

Journal of Glaciology, 2023
The Ward Hunt and Milne ice shelves are the present-day remnants of a much larger ice shelf that once fringed the coast of Ellesmere Island, Canada. These ice shelves possess a unique surface morphology consisting of wave-like rolls that run parallel to ...

The potency of native postbiotics and paraprobiotics in modulating inflammation by affecting the gut–kidney axis

Animal Models and Experimental Medicine, EarlyView.
Native postbiotics and paraprobiotics derived from Lactobacillus and Bifidobacterium strains were administered to dextran sulfate sodium–treated C57BL/6 mice to evaluate their impact on kidney inflammation via the gut–kidney axis. Histological analysis and quantitative polymerase chain reaction of autophagy‐related genes (atg5, atg7, atg12, atg13 ...
