If the analyses are performed in order to give a continuous profile downward from the surface in adequate element to allow interpretation, counting of annual layers leads to an absolute time scale along the core. The essential degree of detail to be studied relies upon of course on the thickness of the annual layers and on the regularity of the cycles, the criterion being that no new important function seems in the profile when the ice core is studied in further element. Here, we focused on the identification of seasonal patterns within the ionic and

Then, to the far left of the graph, a rapid rise in temperature once more as the mud settles down and the temperatures and thus the pressures have additionally settled. The earth warms again and the ices melt, leaving what is left on the poles. You see, if one does not presume lengthy ages, many speedy storms in a time of fluctuating temperatures and world upheaval can account for what we see in that graph. Approximately ninety eight per cent of the Antarctic continent is covered by the ice sheet which is on average about 2,500 metres thick and, at it’s deepest location, 4,seven-hundred metres thick. It is because of this thick ice mass that Antarctica is, on average, the highest continent.
