InSAR observations of ice elevation and velocity fluctuations at the Flade Isblink ice cap, eastern North Greenland [PDF]
, 2010 The 8500 km(2) Flade Isblink ice cap (FIIC) (81 degrees 15'N, 15 degrees 0'W) is the largest ice cap in Greenland. We use repeat-pass interferometric synthetic aperture radar (InSAR) techniques to investigate the form and flow of the FIIC.

Subglacial hydrology and the formation of ice streams [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 Antarctic ice streams are associated with pressurized subglacial meltwater but the role this water plays in the dynamics of the streams is not known. To address this, we present a model of subglacial water flow below ice sheets, and particularly below ice streams.

Advanced Science, EarlyView.The pholidota‐inspired electronic skin is successfully constructed, originally realized four‐state reversible switching of terahertz‐wave reflection, absorption, transmission, and secondary reflection. In response to external demands, it issues deformation instructions, verifies the deformation state after the equipment executes the action, and thus ...

High basal melting forming a channel at the grounding line of Ross Ice Shelf, Antarctica
Geophysical Research Letters, 2016 Antarctica's ice shelves are thinning at an increasing rate, affecting their buttressing ability. Channels in the ice shelf base unevenly distribute melting, and their evolution provides insight into changing subglacial and oceanic conditions.

Temporal variations in the flow of a large Antarctic ice stream controlled by tidally induced changes in the subglacial water system [PDF]
The Cryosphere, 2015 Observations show that the flow of Rutford Ice Stream (RIS) is strongly modulated by the ocean tides, with the strongest tidal response at the 14.77-day tidal period (Msf). This is striking because this period is absent in the tidal forcing.

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.

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity
Advanced Science, EarlyView.This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

Surface undulations of Antarctic ice streams tightly controlled by bedrock topography [PDF]
The Cryosphere, 2013 Full Stokes flow-line models predict that fast-flowing ice streams transmit information about their bedrock topography most efficiently to the surface for basal undulations with length scales between 1 and 20 times the mean ice thickness.

Glacial Geomorphology of southern Alberta, Canada [PDF]
, 2009 During deglaciation from the Last Glacial Maximum three terrestrial ice streams within the south western sector of the Laurentide Ice Sheet competed and coalesced in southern Alberta; the High Plains Ice Stream (HPIS), Central Alberta Ice Stream (CAIS ...
