Measuring thickness of marine ice using IR thermography [PDF]

open access: yesCold Regions Science and Technology, 2019
Abstract There are several challenges to operating in a cold climate. Marine icing is one of them, and its mitigation is vital for marine operations. The presented work is a laboratory-scale setup to measure marine ice thickness. The developed methodology can be applied towards de-/anti-icing setups.

Ice thickness, volume and subglacial relief of Djankuat Glacier (Central Caucasus)

open access: yesЛëд и снег, 2015
In this paper we present and discuss results of radio-echo sounding and modelling of ice thickness of the Djankuat Glacier. This glacier is the reference one for the Central Caucasus and was earlier studied comprehensively, but direct ice thickness ...

A sea-ice thickness retrieval model for 1.4 GHz radiometry and application to airborne measurements over low salinity sea-ice [PDF]

open access: yesThe Cryosphere, 2010
In preparation for the European Space Agency's (ESA) Soil Moisture and Ocean Salinity (SMOS) mission, we investigated the potential of L-band (1.4 GHz) radiometry to measure sea-ice thickness.

Crevasse-induced Rayleigh-wave azimuthal anisotropy on Glacier de la Plaine Morte, Switzerland

open access: yesAnnals of Glaciology, 2019
Crevasses and englacial fracture networks route meltwater from a glacier's surface to the subglacial drainage system and thus influence glacial hydraulics.

Sea-ice thickness measurement based on the dispersion of ice swell

open access: yesThe Journal of the Acoustical Society of America, 2012
The dispersion of flexural waves propagating in the Arctic sea ice cover is exploited in order to locally measure the ice thickness. The observed dispersion, for waves filtered in the 4–20 s period interval, at up to 4 broad-band seismometers deployed in Spring 2007 near the North Pole, is compared to a parameterized model that accounts for a complex ...

Bias-corrected estimates of glacier thickness in the Columbia River Basin, Canada

open access: yesJournal of Glaciology, 2020
Several global datasets of glacier thickness exist, but the number of observations from western Canada are sparse and spatially biased. To supplement these limited observations, we measured ice thickness with ice penetrating radar on five glaciers in the

Application of GNSS Interferometric Reflectometry for the Estimation of Lake Ice Thickness

open access: yesRemote Sensing, 2020
Lake ice thickness is a sensitive indicator of climate change largely through its dependency on near-surface air temperature and on-ice snow mass (depth and density). Monitoring of the seasonal variations and trends in ice thickness is also important for

Interannual variability in Transpolar Drift summer sea ice thickness and potential impact of Atlantification [PDF]

open access: yesThe Cryosphere, 2021
Changes in Arctic sea ice thickness are the result of complex interactions of the dynamic and variable ice cover with atmosphere and ocean. Most of the sea ice exiting the Arctic Ocean does so through Fram Strait, which is why long-term measurements of ...

Discrimination Algorithm and Procedure of Snow Depth and Sea Ice Thickness Determination Using Measurements of the Vertical Ice Temperature Profile by the Ice-Tethered Buoys

open access: yesSensors, 2018
Snow depth and sea ice thickness in the Polar Regions are significant indicators of climate change and have been measured over several decades by ice-tethered buoys.

MeasureIce: accessible on-the-fly measurement of ice thickness in cryo-electron microscopy [PDF]

open access: yesCommunications Biology, 2021
Abstract Ice thickness is arguably one of the most important factors limiting the resolution of protein structures determined by cryo-electron microscopy (cryo-EM). The amorphous atomic structure of the ice that stabilizes and protects biological samples in cryo-EM grids also imprints some additional noise in cryo-EM images.
