Sea-ice freeboard and thickness in the Ross Sea from airborne (IceBridge 2013) and satellite (ICESat 2003–2008) observations

Annals of Glaciology, 2020
NASA's Operation IceBridge mission flew over the Ross Sea, Antarctica (20 and 27 November 2013) and collected data with Airborne Topographic Mapper (ATM) and Digital Mapping System (DMS).

Improving the spatial distribution of modeled Arctic sea ice thickness [PDF]

, 2005
The spatial distribution of ice thickness/draft in the Arctic Ocean is examined using a sea ice model. A comparison of model predictions with submarine observations of sea ice draft made during cruises between 1987 and 1997 reveals that the model has the

Influence of ice crystal shape on retrieval of cirrus optical thickness and effective radius: A case study [PDF]

, 2009
Airborne measurements of spectral upwelling radiances (350â  2200 nm) reflected by cirrus using the Spectral Modular Airborne Radiation measurement sysTem (SMART)-Albedometer were made over land and water surfaces.

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

Annals 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.

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

Journal 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

Ice volume distribution and implications on runoff projections in a glacierized catchment [PDF]

Hydrology and Earth System Sciences, 2012
A dense network of helicopter-based ground-penetrating radar (GPR) measurements was used to determine the ice-thickness distribution in the Mauvoisin region.

Airborne radar ice thickness measurements in Antarctica 1994-2007

, 2023
In these datasets we publish ice thickness data collected by ice-penetrating radar measurements of the Alfred Wegener Institute between the years 1994 and 2007.

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

Remote 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

Evaluation of Operation IceBridge quick-look snow depth estimates on sea ice [PDF]

, 2015
We evaluate Operation IceBridge (OIB) ‘quick-look’ (QL) snow depth on sea ice retrievals using in situ measurements taken over immobile first-year ice (FYI) and multi-year ice (MYI) during March of 2014. Good agreement was found over undeformed FYI (-4.5

The relation between sea ice thickness and freeboard in the Arctic [PDF]

The Cryosphere, 2010
Retrieval of Arctic sea ice thickness from CryoSat-2 radar altimeter freeboard data requires observational data to verify the relation between these two variables.
