Basal topographic controls on the stability of the West Antarctic ice sheet: lessons from Foundation Ice Stream

Annals of Glaciology, 2017
Using observations of basal topography, ice thickness and modern accumulation rates, we use theory and a dynamic flowline model to examine the sensitivity of Antarctica's Foundation Ice Stream to changes in sea level, accumulation and buttressing at the ...

Modeling ice stream flow [PDF]

Eos, Transactions American Geophysical Union, 2011
Ice flow speed within an ice sheet can vary from a few meters to thousands of meters per year. Fast flowing ice streams can affect sea level, and their flow variation is one factor that determines whether an ice sheet is gaining or losing mass. But different ice streams exhibit different behaviors, and these spatial and temporal variations are not well

Aramid Nanofiber Aerogels: Preparation, Modification, Composite Fabrication, and Applications

Advanced Materials, EarlyView.
Different forms of aramid nanofibers (ANFs) and especially aerogels from them, offer a sustainable route to high‐performance biomimetic nanocomposites. Due to the cartilage‐like architecture, ANF‐based materials enable breakthroughs in energy, electromagnetic, biomedical, and water purification technologies.

A viscoelastic model of ice stream flow with application to stick-slip motion

Frontiers in Earth Science, 2016
Stick-slip motion such as that observed at Whillans Ice Stream, WestAntarctica, is one example of transient forcing significantly affecting longer-termice-stream dynamics.

Superimposition of ribbed moraines on a palaeo‐ice‐stream bed: implications for ice stream dynamics and shutdown [PDF]

Earth Surface Processes and Landforms, 2008
AbstractThe sediments and landforms preserved on palaeo‐ice‐stream beds can provide important information about their subglacial conditions and flow mechanisms, and the processes accompanying their shutdown. In this paper, detailed observations of an intriguing subglacial landform assemblage of ribbed moraines superimposed on glacial lineations on the ...

Nanoarchitectonics of Metal–Organic Framework and Nanocellulose Composites for Multifunctional Environmental Remediation

Advanced Materials, EarlyView.
Nanoscale metal–organic frameworks (MOFs) and nanocellulose composites have significant potential for the multi‐functional remediation of the environment. This review focused on the synthesis strategies (in situ growth, ex situ growth, and other approaches), typical forms (aerogel, hydrogel, beads, and membrane), and applications in the removal of ...

Basal melt beneath Whillans Ice Stream and Ice Streams A and C, West Antarctica [PDF]

Annals of Glaciology, 2003
AbstractWe have used a recently derived map of the velocity of Whillans Ice Stream and Ice Streams A and C, West Antarctica, to help estimate basal melt. Ice temperature was modeled with a simple vertical advection–diffusion equation,“tuned” to match temperature profiles.
