Ice Composition and Glacier Dynamics

1991
The study of ice composition represents an effective tool in our understanding of the dynamics of glaciers, ice sheets and ice shelves. The authors of this work relate the distribution of isotopes and impurities in ice masses to ice flow, to the key zone close to the ice-substratum interface and to the mechanisms effective in the contact zone between ...

Permafrost creep and rock glacier dynamics

Permafrost and Periglacial Processes, 2006
Final report of the Task Force on Permafrost Creep and Rock Glacier Dynamics. This Task Force was established in 1998 by the International Permafrost Association (IPA) and the International Commission on Snow and Ice (ICSI; now the Commission on Cryospheric Sciences, CCS) with Wilfried Haeberli and Bernard Hallet as co-chairs in order: (1) to define ...

Dynamics of Glacier Flow

2009
As mentioned in the introduction (Chapter 1), the size of land ice masses spans several orders of magnitude, from large ice sheets of a few thousand kilometres in diameter down to small glaciers of a few hundreds of metres in length. Consequently, the scaling given for ice sheets in Chapter 5 [Eqs.

Dynamics of an alpine cirque glacier

American Journal of Science, 2010
Alpine cirques are excavated by glacial erosion, a process that depends in turn on the movement of ice by basal sliding. Cirque glacier flow is usually depicted as rotational sliding of a rigid block, but this model is based on little evidence and implies unorthodox glacier behavior given typical cirque dimensions.

Dynamics of the Glaciers of Georgia

2017
This chapter discusses the dynamics of the glaciers of Georgia by periods of individual decades since the LIA to the present day. The rates of old glaciers are reconstructed based on the micro-stade moraines; also the topographic maps of the 19–20th centuries and the modern satellite images (Landsat/ASTER) are used.

Laboratory Models of Glacier Dynamics

Geological Society of America Bulletin, 1972
Excellent laboratory models of glaciers were produced by pouring a mixture of molding plaster and water down a prefashioned trough of nonabsorbent material. The plaster models simulate the dynamics of glacier flow and accurately display many surface and internal structures common to real glaciers, including crevasse and flow patterns, icefalls and ...

Seasonal dynamics of Earth’s glaciers and ice sheets

Science
The sensitivity of Earth’s glaciers to environmental change is on display each year as they change speed with the seasons, and a glacier’s response to warming from winter to summer may help predict its response to warming on multiyear timescales. We present a global analysis of seasonal glacier and ice sheet dynamics, finding that seasonal velocity ...
