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

Ice sheet extent and early deglacial history of the southwestern sector of the Greenland ice sheet [PDF]

, 2009
The offshore and coastal geomorphology of southwest Greenland records evidence for the advance and decay of the Greenland Ice Sheet during the Last Glacial Maximum.

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

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 ...

The distribution of basal motion beneath a High Arctic polythermal glacier [PDF]

, 2003
The longitudinal pattern of surface velocity of a large, predominantly colds polythermal glacier (John Evans Glacier, Ellesmere Island, Canada) was measured over summer and winter periods.

An ice-sheet scale comparison of eskers with modelled subglacial drainage routes [PDF]

, 2015
Eskers record the signature of channelised meltwater drainage during deglaciation providing vital information on the nature and evolution of subglacial drainage.

Outlet glacier flow response to surface melt: based on analysis of a high-resolution satellite data set

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 ...

Potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets [PDF]

, 2013
We use the Shreve hydraulic potential equation as a simplified approach to investigate potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets. We validate the method by demonstrating its ability

Bayesian Inference of Ice Softness and Basal Sliding Parameters at Langjökull

Frontiers in Earth Science, 2021
We develop Bayesian statistical models that are designed for the inference of ice softness and basal sliding parameters, important glaciological quantities.

Impact of boundary conditions on the modeled thermal regime of the Antarctic ice sheet [PDF]

The Cryosphere
A 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
