Effect of Ice Thickness on Ice Forces
Offshore Technology Conference, 1974ABSTRACT Ice forces are the main concern in designing offshore structures such as drilling platforms, translating points, or bridge piers in arctic regions. Even though some results have been obtained by field measurements in recent years, there are still significant gaps in the knowledge of ice forces on structures.

Utilizing CryoSat-2 sea ice thickness to initialize a coupled ice-ocean modeling system
Advances in Space Research, 2018 Two CryoSat-2 sea ice thickness products derived with independent algorithms are used to initialize a coupled ice-ocean modeling system in which a series of reanalysis studies are performed for the period of March 15, 2014–September 30, 2015. Comparisons

Estimation of Thin-Ice Thickness and Discrimination of Ice Type From AMSR-E Passive Microwave Data
IEEE Transactions on Geoscience and Remote Sensing, 2019Detection of thin-ice thickness with microwave radiometers, such as the Advanced Microwave Scanning Radiometer-Earth Observing System (AMSR-E), is very effective for the estimation of sea-ice production, which causes dense water driving ocean ...

Thickness of ice on perennially frozen lakes
Nature, 1985The dry valleys of southern Victoria Land, constituting the largest ice-free expanse in the Antarctic, contain numerous lakes whose perennial ice cover is the cause of some unique physical and biological properties. Although the depth, temperature and salinity of the liquid water varies considerably from lake to lake, the thickness of the ice cover is

Measuring Ice Thickness with Cygnss Altimetry
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018Cyclone Global Navigation Satellite System (CYGNSS) is collecting GPS signals reflected from two high altitude lakes with ice cover during Winter 2017–2018. Coherent reflections occur at the ice/water interface and carrier phase altimetry is used to estimate the draft of the ice cover. Simulated data are created using a forward model. Signal processing

DRILL FOR DETERMINING THICKNESS OF ICE
Canadian Journal of Research, 1947A device is described for quickly drilling through ice to determine its thickness. It consists of an electric heater mounted at the tip of a rod long enough to penetrate to the desired depth. The unit drills a half inch diameter hole at the rate of about two feet per minute.

1989
Abstract : Prototype Upward Looking Sonar (ULS) instruments that monitor time series of ice draft from oceanographic moorings have been designed, built, tested and deployed in arctic waters. The measured time series recovered from these instruments reveal many geophysically significant, quantitative aspects of the sea ice draft distribution that have ...

Estimating the thickness of sea ice
Journal of Geophysical Research: Oceans, 1989Sea ice freeboard, thickness, and snow depth were measured from a series of closely spaced (5 to 10 m) drill hole sites from five free‐floating multiyear ice floes in the Beaufort Sea during the spring of 1986 and 1987. A regression of ice thickness on ice draft was performed on the data from each floe and for the combined data set.
