Radio Echo Sounding: Absorption and Scattering by Water Inclusion and Ice Lenses [PDF]
Journal of Glaciology, 1972 Abstract The absorption of radio waves propagating through naturally occurring waters varies greatly with the electrical conductivity. Glacier melt water is very transparent and the attenuation by melt water layers is due to reflexion of power, whereas the attenuation of sea-water layers is due to absorption. The attenuation of soaked

Location of a new ice core site at Talos Dome (East Antarctica)
Annals of Geophysics, 2006 In the frame of glaciology and palaeoclimate research, Talos Dome (72°48lS; 159°06lE), an ice dome on the East Antarctic plateau, represents the new selected site for a new deep ice core drilling. The increasing interest in this region is due to the fact

Radio-Echo Sounding: Focusing Effects in Wavy Strata [PDF]
Geophysical Journal International, 1971 Summary An airborne radio-echo sounding system, employing a wide downward-looking beam, has produced records of the Antarctic ice sheet containing fault-like, near-vertical lines through the strata of partially-reflecting layers within the ice. It is shown that interpretation of these lines as near-vertical faults is in general incorrect, and a more

Radio Echo-Sounding of Riiser-Larsenisen (Abstract only) [PDF]
Annals of Glaciology, 1982 The Norwegian Antarctic Research Expedition 1978–79 used the Scott Polar Research Institute Mk IV radio echo-sounding system fitted in a Bell 206B helicopter to survey 620 km of Riiser-Larsenisen and 100 km across the outer part of Stancomb-Wills Ice Stream.

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

Titanium Suboxides Responsible for Electronic Anomaly Near Room Temperature in the Ti3C2Tx MXene
Advanced Functional Materials, EarlyView.Our multi‐technique study reveals that the near‐room‐temperature anomaly in Ti3C2Tx MXene is linked to titanium suboxide nanodomains, including Ti3O5, embedded within the MXene host. Their temperature‐driven transformation provides an alternative explanation to solvent‐ and swelling‐based models and offers new insight into the thermally activated ...
