Entrainment, transport and concentration of meteorites in polar ice sheets [PDF]

Glaciers and ice sheets act as slow-moving conveyancing systems for material added to both their upper and lower surfaces. Because the transit time for most materials is extremely long the ice acts as a major global storage facility.

IceCube's In-Ice Radio Extension: Status and Results

, 2010
In 2006-2010, several Radio Frequency (RF) detectors and calibration equipment were deployed as part of the IceCube array at depths between 5 to 1400 meters in preparation for a future large scale GZK neutrino detector.

Geothermal heat flux of Ridge B region in Antarctica inferred from basal dry–wet distribution

Journal of Glaciology
Ridge B is one of the least studied areas in Antarctica but has been considered to be a potential location for the oldest ice on Earth. Among important parameters for calculating where very old ice may exist, geothermal heat flux (GHF) is critical but ...

Glaciological bodies: Australian visions of the Antarctic ice sheet

International Review of Environmental History, 2018
Building upon work in environmental history and the history of science that has critically investigated the relationships between humans and ice, this article approaches the history of the Antarctic ice sheet through the particular experiences, practices and ideas of Australian glaciologists between the late 1940s and late 1980s. It seeks to understand

Drilling deep in South Pole Ice

, 2014
To detect the tiny flux of ultra-high energy neutrinos from active galactic nuclei or from interactions of highest energy cosmic rays with the microwave background photons needs target masses of the order of several hundred cubic kilometers.

Snow metamorphism: a fractal approach

, 2010
Snow is a porous disordered medium consisting of air and three water phases: ice, vapour and liquid. The ice phase consists of an assemblage of grains, ice matrix, initially arranged over a random load bearing skeleton.

Mapping Antarctic Blue Ice Areas With Sentinel-2A/B Images and LightGBM Model

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Antarctic blue ice plays a crucial role in surface energy balance and paleoclimate research. A high-accuracy and comprehensive dataset of blue ice areas (BIAs) is essential for understanding climate dynamics and environmental changes in the region. While

A direct helicopter EM sea ice thickness inversion, assessed with synthetic and field data [PDF]

, 2007
Accuracy and precision of helicopter electromagneticHEM sounding are the essential parameters for HEM seaicethickness profiling. For sea-ice thickness research, thequality of HEM ice thickness estimates must be better than10 cm to detect potential ...

A synthesis of the basal thermal state of the Antarctic ice sheet

Journal of Glaciology
The basal thermal state of the Antarctic ice sheet (AIS)—whether the base is frozen or thawed—fundamentally underpins its flow and is an important factor in understanding its large-scale response to external forcings.
