Mercury in the Greenland Ice Sheet
Nature, 1978REPORTS of the mercury content of the Greenland Ice Cap have varied within one or two orders of magnitude. Weiss et al.1 found an increase from about 50 ng per kg in ancient deposit layers to about 100 ng per kg in surface samples from 1964 to 1965, and concluded that there was an increase in man's global input of mercury to the atmosphere.

Is the Greenland Ice Sheet bistable?
Paleoceanography, 1995Ice core work on Greenland has produced dramatic evidence for an instability of the climate system in the North Atlantic sector. In this paper, we provide climate modeling results indicating another possible example of a multiple equilibrium climate state, where such behavior might apply to the ice sheet itself.

Folding in the Greenland Ice Sheet
Journal of Geophysical Research: Solid Earth, 1987The deformation of layering into folds is modeled for a linear viscous medium moving over a décollement. Folds are generated by flow variations caused by relief on the décollement, variations in friction, or both. The model is applied to folds forming now in the Greenland Ice Sheet near Dye 3, for which more complete data are available than for ...

ICE CORES | Dynamics of the Greenland Ice Sheet
2007The Greenland ice sheet is the largest ice sheet in the Northern Hemisphere. It plays an important role in climate research because of its location in the North Atlantic, which is a region thought to play a key role in climate changes on Earth. Because snow accumulation rates in the central areas have been sufficiently high, annual layers may be ...

Dynamics of the Greenland Ice Sheet
2007The Greenland ice sheet is the largest ice sheet in the Northern Hemisphere. Snow accumulation is high due to the proximity of the North Atlantic, and annual layers have been resolved in ice core records through the last glacial period. Ice flows from the interior toward the margin, where it is lost by surface melting or drains through fast-flowing ...
