TL;DR: In this paper, the Nd, Sr and Pb isotopic compositions of silt particles from the basal silty ice of two deep ice cores in Central Greenland, GISP 2 and GRIP, are compared to those of the subglacial rock material (dolerite boulder, till and granitic bedrock).

TL;DR: In this article, a non-linear, one-dimensional flow model of an ice sheet is used to investigate how net accumulation-rate changes affect the time evolution of: (1) the ice-sheet thickness, the vertical strain rate, and the corresponding internal annual-layer structure.

TL;DR: The microstructures and microchemistry of four US International Trans-Antarctic Scientific Expedition ice cores were examined, at three depths (30, 60, 90 m) each, using scanning electron microscopy, including electron backscattered patterns and energy-dispersive spectroscopy (EDS), in order to assess the relationship between chemical and physical properties as discussed by the authors.

TL;DR: In this article, a scanning electron microscope (SEM) coupled with X-ray spectroscopy and electron back-scattered diffraction patterns was used to examine firn in cores retrieved by the United States International Trans-Antarctic Scientific Expedition.

TL;DR: In the Siple Dome and Greenland Ice Sheet Project 2 (GISP2) ice cores, a dramatic change to a shear fabric appears to be directly related to the higher concentration of volcanic particles in the ice between 700 and 800 m as discussed by the authors.
