Changes in the Velocity Structure of the Greenland Ice Sheet [PDF]
Science, 2006 Using satellite radar interferometry observations of Greenland, we detected widespread glacier acceleration below 66° north between 1996 and 2000, which rapidly expanded to 70° north in 2005. Accelerated ice discharge in the west and particularly in the east doubled the ice sheet mass deficit in the last decade from 90 to 220 cubic kilometers per year.

Influence of Velocity on Ice-Cone Interaction
, 2001 A series of upward breaking cone tests was conducted at NRC/IMD’s ice tank in level ice using EG/AD/S correct density model ice. Cone angles of 45° and 60° were tested. The effect of ice draft velocity in the range 0.005 to 0.5 m/s was studied for ice thicknesses ranging from 35 to 110 mm. The mean peak forces in both horizontal and vertical directions

Ice Floe Trajectory Under the Action of Propeller Pumping
Shanghai Jiaotong Daxue xuebao, 2021 In order to study the influence of propeller pumping action on ice trajectory during the process of ice propeller interference, this paper built a motion trajectory measurement platform based on circulating water tank, combining high-speed camera and the

Subglacial roughness of the Greenland Ice Sheet: relationship with contemporary ice velocity and geology [PDF]
The Cryosphere, 2019 Abstract. The subglacial environment of the Greenland Ice Sheet (GrIS) is poorly constrained, both in its bulk properties, for example geology, presence of sediment, and of water, and interfacial conditions, such as roughness and bed rheology. There is, therefore, limited understanding of how spatially heterogeneous subglacial properties relate to ice ...

Journal of Glaciology, 2023 The dynamics of the Greenland Ice Sheet are affected by surface meltwater reaching the base of the ice, altering ice contact with the bedrock. Lack of understanding of this evolution hampers the ability to predict the effects of increasing temperatures ...

Impact of boundary conditions on the modeled thermal regime of the Antarctic ice sheet [PDF]
The CryosphereA realistic initialization of ice flow models is critical for predicting future changes in ice sheet mass balance and their associated contribution to sea level rise. The initial thermal state of an ice sheet is particularly important, as it controls ice

Ice Crystal Terminal Velocities [PDF]
Journal of the Atmospheric Sciences, 1972 Terminal velocities of different ice crystal forms were calculated, using the most recent ice crystal drag coefficients, aspect ratios, and densities. The equations derived were primarily for use in calculating precipitation rates by sampling particles with an aircraft in cirrus clouds, and determining particle size in cirrus clouds by Doppler radar ...
