Subglacial controls on the flow of Institute Ice Stream, West Antarctica
Annals of Glaciology, 2016 The Institute Ice Stream (IIS) rests on a reverse-sloping bed, extending >150 km upstream into the ~1.8 km deep Robin Subglacial Basin, placing it at the threshold of marine ice-sheet instability. Understanding IIS vulnerability has focused on the effect

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma
Advanced Engineering Materials, EarlyView.The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Constraining the geothermal heat flux in Greenland at regions of radar-detected basal water
Journal of Glaciology, 2019 The spatial distribution of basal water critically impacts the evolution of ice sheets. Current estimates of basal water distribution beneath the Greenland Ice Sheet (GrIS) contain large uncertainties due to poorly constrained boundary conditions ...

Journal of General Internal Medicine, 2013 Alice was in her 80s and appeared the quintessential grandmother: she had short, neatly-cropped gray hair and a pleasantly round face that gave her the appearance of being incapable of malediction. Her shoes were arranged neatly on the floor next to her bed; they were unmistakably non-athletic, beige “grandma shoes” with thick soles and Velcro.
