If the analyses are performed so as to provide a continuous profile downward from the floor in enough element to allow interpretation, counting of annual layers leads to an absolute time scale along the core. The essential diploma of detail to be studied relies upon after all on the thickness of the annual layers and on the regularity of the cycles, the criterion being that no new vital function seems in the profile when the ice core is studied in additional detail. Here, we centered on the identification of seasonal patterns within the ionic and
horizons offered by historically recognized volcanic eruptions. The obtained age

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 soften, leaving what’s 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 covered by the ice sheet which is on common 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 best continent.
