Flow properties of the ice from the Greenland Ice Core Project ice core: The reason for folds?

Journal of Geophysical Research: Oceans, 1997
Long‐term deformation tests on ice from the Greenland Ice Core Project (GRIP) deep ice core show that ice from the different climate zones in the ice core has flow properties correlated with the concentrations of impurities in the sample. The deformation tests are performed by uniaxial unconfined compression at −16°C with an octahedral compression ...

ICE CORES

2014
Ice cores from Antarctica, from Greenland, and from a number of smaller glaciers around the world yield a wealth of information on past climates and environments. Ice cores offer unique records on past temperatures, atmospheric composition (including greenhouse gases), volcanism, solar activity, dustiness, and biomass burning, among others.

Ice core methodology

2012
Willi Dansgaard is a Danish scientist who is credited with the original idea of using ice cores to probe temperature changes over the past thousands of years. His book provides a very interesting history of the early evolution of this technique (Dansgaard, 2005).

Ice core data

2012
Oard (2005) provides an excellent introductory overview of ice cores from the ice sheets at Greenland and Antarctica. The two great ice sheets presently existent on Earth are located where landmasses exist near the poles: Greenland and Antarctica. Both ice sheets store a huge amount of water, as indicated in Table 4.1.

ICE CORE METHODS | Methane Studies

2007
This article presents a state-of-the-art of atmospheric methane reconstruction based on ice-core studies. Starting with a biogeochemical overview of the methane cycle, it explains the processes of gas diffusion in firn and trapping in ice. It presents and discusses the anthropogenic impact on atmospheric CH4, and then the trend of this greenhouse gas ...

Making an Ice Core

Journal of Geological Education, 1995
A simple exercise suitable for grades three through eight in which students construct a simulated ice core is described. Materials required include only a freezer, food coloring, a glass or plastic bottle, and water. This hands-on exercise provides an opportunity for learning several important lessons.
