If the analyses are carried out so as to give a steady profile downward from the surface in adequate element to allow interpretation, counting of annual layers leads to an absolute time scale alongside the core. The needed diploma of element to be studied relies upon in fact on the thickness of the annual layers and on the regularity of the cycles, the criterion being that no new significant function appears within the profile when the ice core is studied in further detail. Here, we centered on the identification of seasonal patterns within the ionic and

Then, to the far left of the graph, a speedy rise in temperature again as the mud settles down and the temperatures and thus the pressures have additionally settled. The earth warms again and the ices soften, leaving what is left on the poles. You see, if one does not presume long ages, many rapid storms in a time of fluctuating temperatures and world upheaval can account for what we see in that graph. Approximately 98 per cent of the Antarctic continent is roofed by the ice sheet which is on average about 2,500 metres thick and, at it’s deepest location, 4,700 metres thick. It is due to this thick ice mass that Antarctica is, on average, the highest continent.
