The measurements on the ice from the ice core have little or no scientific value if they cannot be related to a specific time or time period. It is therefore one of the most important tasks before and after an ice core has been drilled to establish a time scale for the ice core. Dating of ice cores is done using a combination of annual layer counting and computer modelling. Ice core time scales can be applied to other ice cores or even to other archives of past climate using common horizons in the archives.

Annual layers in the ice can be counted like annual rings in a tree.

The United States could lower the number of its armed forces in Iraq to approximately 3,, The Wall Street Journal reported on Friday, citing several country’s officials. At the moment, the Pentagon has 5, active troops in the Middle Eastern country, and the reduction by one third would bring the total number of soldiers to the one seen in , the report read.

A week ago, US President Donald Trump signaled the idea of limiting the military presence in the area, noting it might come “shortly.

Find out why ice core research is so important for our understanding of climate change and how we drill and analyse the ice cores. For a detailed look at how ice cores are recovered from Antarctica watch this video. Why do scientists drill ice cores?

Image processing and analysis software provide the capability to extract quantitative information from digital images, and microstructural modeling software is used.

The oldest ice core ever drilled outside the polar regions may contain ice that formed during the Stone Age–more than , years ago, long before modern humans appeared. Researchers from the United States and China are now studying the core–nearly as long as the Empire State Building is tall–to assemble one of the longest-ever records of Earth’s climate history. What they’ve found so far provides dramatic evidence of a recent and rapid temperature rise at some of the highest, coldest mountain peaks in the world.

The change is most noticeable on the Guliya Ice Cap, where they drilled the latest ice core. In this region, the average temperature has risen 1. Lonnie Thompson, Distinguished University Professor in the School of Earth Sciences at The Ohio State University and co-leader of the international research team, said that the new data lend support to computer models of projected climate changes.

There, glaciologist Yao Tandong secured funding for a series of joint expeditions from the Chinese Academy of Sciences. Continued warming in these regions will result in even more ice melt with the likelihood of catastrophic environmental consequences,” Yao noted. The name “Third Pole” refers to high mountain glaciers located on the Tibetan Plateau and in the Himalaya, in the Andes in South America, on Kilimanjaro in Africa, and in Papua, Indonesia–all of which have been studied by the Ohio State research team.

Of particular interest to the researchers is a projection from the Intergovernmental Panel on Climate Change that future temperatures on the planet will rise faster at high altitudes than they will at sea level. The warming at sea level is expected to reach 3 degrees Celsius by the year , and possibly double that, or 6 degrees Celsius, at the highest mountain peaks in the low latitudes.

Around the world, hundreds of millions of people depend on high-altitude glaciers for their water supply.

Microstructures from deep ice cores reflect the dynamic conditions of the drill location as well as the thermodynamic history of the drill site and catchment area in great detail. Ice core parameters crystal lattice-preferred orientation LPO , grain size, grain shape , mesostructures visual stratigraphy as well as borehole deformation were measured in a deep ice core drilled at Kohnen Station, Dronning Maud Land DML , Antarctica.

The results suggest a division of the core into five distinct sections, interpreted as the effects of changing deformation boundary conditions from triaxial deformation with horizontal extension to bedrock-parallel shear. Region 1 uppermost approx. Region 2 approx. In this region approx. Region 3 approx. The fully developed single maximum LPO in region 4 approx. Region 5 below approx. The details of structural observations are compared with results from a numerical ice sheet model PISM, isotropic for comparison of strain rate trends predicted from the large-scale geometry of the ice sheet and borehole logging data.

This comparison confirms the segmentation into these depth regions and in turn provides a wider view of the ice sheet. Variations in net mass transport of ice towards the ocean lead to variations in ice flux and eventually sea-level variations. Ice sheets possess the highest potential to cause drastic changes within the global water cycle owing to their large water reservoir.

An ice core is a core sample that is typically removed from an ice sheet or a high mountain glacier. Since the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper, and an ice core contains ice formed over a range of years. Cores are drilled with hand augers for shallow holes or powered drills; they can reach depths of over two miles 3.

The physical properties of the ice and of material trapped in it can be used to reconstruct the climate over the age range of the core.

The ice core dating software is a program designed to create a depth-age scale from ice core glaciochemical records. It reads data from comma separated files that contain depth vs. The user selects the elements he wants to plot, and then dynamically perform the dating process on the charts drawn.

Much of the global annual mean temperature change over Quaternary glacial cycles can be attributed to slow ice sheet and greenhouse gas feedbacks, but analysis of the short-term response to orbital forcings has the potential to reveal key relationships in the climate system.

In particular, obliquity and precession both produce highly seasonal temperature responses at high latitudes. This comparison reveals mismatches between the annual mean response to obliquity and precession in models versus the signals within Antarctic ice cores. Weighting the model-based reconstruction toward austral winter or spring reduces these discrepancies, providing evidence for a seasonal bias in ice cores.
