This is part two of a two-part series about the first Antarctic winter solstice.
How it happened.
About 90 years ago, about 90 million year ago, a giant iceberg called a glacial morain, named after a Greek f코리아 카지노igure, sank around Antarctica.
During the day, the ice on the surface was not very thick and thinned quickly. But gradually and rapidly the ice became much thicker and much harder to come by and a few thousand years after the iceber더킹 카지노 3 만g sank, this ice was replaced by new glaciers that have covered vast areas of the southern hemisphere.
What the scientists – from Britain, Australia and France – discovered is that the glaciers were gradually being replaced with ice that was much more compact than the rest and much more stable.
They found that this ice started melting around 25,000 years ago and had to be replaced with more recent ice at a rate of about 5cm a year (1ft). The glacier gradually melted off and over millions of years a much larger part of it was replaced by new ice at some rate that was now faster and much less compact than the old ice.
All this takes place over a period of thousands of years.
In fact, our Antarctic research team is doing something unusual in the geological record – we are taking ice cores that used to be on Antarctica and studying them at Antarctica in order to try to understand when, where and how these ice ages ended.
How did they find out about the ice-based life form?
The ice is a mass of ice floating on water. If you look very closely, you will see tiny craters on the surface which are actually the water-free deposits of some deep ocean water that was once in the middle of Antarctica and it’s about 60m (230ft) deep. The ice is very compact.
We can actually see them from space.
So we see these tiny craters. But what the scientists do with ice cores isn’t si카지노 슬롯 머신 규칙mply to drill them deep inside the continent – instead, they drill them into the ground where they are frozen and freeze them on a subfloor for 3,000 years. That results in a sort of ice sheet on top of the Earth that’s at least as thin as sea level and much more stable. We can actually see them from space. But we think they ca
