Data about ancient ocean
Recently carried out researches have forced scientists to recognise amazing fluctuations of level of the World ocean in rather recent past. It has appeared that an order 100 thousand years ago the ocean has sharply increased the level approximately by 15 metres, then so sharply it has lowered.
Usually change of level of ocean is connected with polar ices. Than thaws glaciers - that above ocean level more. Thus, as scientists mark, process is periodical. Duration of one such cycle makes approximately 100 thousand years.
Meanwhile, calculations show that fluctuations of level of ocean about which there is a speech, occurred extremely promptly - on the specified 15 metres the ocean "has grown up" literally for a millenium. Level decrease has occurred for so short term to geochronological measures. An explanation to this phenomenon scientists yet do not send.
