Glaciological regime of the Ross Ice Shelf

Journal of Geophysical Research, 1962
A description of the floating Ross ice shelf in Antarctica, determined from miscellaneous studies between 1957 and I960, is provided by contoured maps giving values of ice thickness, ocean floor depth, surface snow density, average annual temperature, and average annual snow accumulation.

ICE REGIME OF THE ABAKAN RIVER

Themed collection of papers from Foreign International Scientific Conference «Modern research on the way to a new scientific revolution». by HNRI «National development» in cooperation with AFP (Puerto Cabezas, Nicaragua). November 2024. – Havana (Cuba)
The study of the ice regime of rivers is mandatory when designing hydraulic structures. The thickness of the ice affects the bearing capacity of the ice sheet, which is necessary to know when setting up crossings. The empirical method allows you to determine the thickness of the ice.

Classification of Ice-Induced Vibration Regimes of Offshore Wind Turbines

Volume 6: Polar and Arctic Sciences and Technology, 2022
Abstract Ice-induced vibrations of offshore wind turbines on monopile foundations were investigated experimentally at the Aalto Ice Tank. A real-time hybrid test setup was developed allowing to accurately simulate the motion of a wind turbine in interaction with ice, incorporating the multi-modal aspects of the interaction and the effect

Temperature regime of antarctic fast ice

Polar Geography and Geology, 1981
Abstract Direct measurements of fast‐ice temperatures in Alasheyev Bight demonstrate the strong effect of snow cover on temperature amplitude. A change from cyclonic weather to drainage wind with low air temperature is accompanied by removal of part of the snow cover that acts as a thermal insulator, reducing the amplitude of the fast‐ice temperatures.

The Changing Ice Regime of Northeastern Baffin Bay

SNAME 10th International Conference and Exhibition on Performance of Ships and Structures in Ice, 2012
The sea ice concentrations and areal extent in Baffin Bay have undergone major reductions over the past 31 years (1981-2011). Of particular interest is the Northeastern Baffin Bay area off West Greenland, which is a promising frontier area for oil and gas exploration.

Impacts of Dam Removal on Riverine Ice Regime

Journal of Cold Regions Engineering, 2002
The impact of dam removal on the ice regime of northern rivers has largely been ignored in the recent push for removal of dams to restore or improve aquatic habitat.

Effect of river barrages on ice regime

Journal of Hydraulic Research, 1990
Ice regime of natural rivers is influenced by climate, water regime and channel morphology. Since channel morphology and water regime are influenced by river dams, changes in ice conditions can be expected. Ice appears commonly on the Hungarian rivers uninfluenced by human activities.

Ice Regime for Basins and Pumped-Storage Facilities

Applied Mechanics and Materials, 2015
The article deals with various optional combinations of upper and lower basins in pumped-storage power plants (PSPP) which determine ice conditions that may appear on water surfaces, headwater discharge basins and slopes basins. There are also examples of calculation methods of ice regimes that are given in this article.

Reservoir Operations and Their Effect on Ice Regime

Cold Regions Engineering, 2002
The Baltimore District of the U.S. Army Corps of Engineers recently undertook a study to determine whether a change in the operation of one of its flood control reservoirs would affect the degree of flood protection downstream. The intended operational change entails eliminating the current practice of providing an additional winter drawdown, which ...

Ground penetrating radar for measurement of ice regime

Abstract The ground penetrating radar(GPR) is a new method for measurement of ice regime. For overcoming disadvantages of single frequency radar system, this study presents a double frequency radar system with 100 MHz and 1500 MHz working frequency to measure water depth and ice thickness at the same time.
