The physical properties of the ice and of material trapped in it can be used to reconstruct the climate over the age range of the core.The proportions of different oxygen and hydrogen isotopes provide information about ancient temperatures, and the air trapped in tiny bubbles can be analysed to determine the level of atmospheric gases such as carbon dioxide.As further layers build up, the pressure increases, and at about 1500 m the crystal structure of the ice changes from hexagonal to cubic, allowing air molecules to move into the cubic crystals and form a clathrate.

Depths of over 400 m were reached, a record which was extended in the 1960s to 2164 m at Byrd Station in Antarctica.
Soviet ice drilling projects in Antarctica include decades of work at Vostok Station, with the deepest core reaching 3769 m.
“If that were true, they would be lowering their standards. In fact, she notes that older women are a lot more selective than older men and younger women are when it comes to picking a partner If anything, it’s more of a level playing field when it comes to midlife dating.
In a talk before boomers (you can watch it below), Adshade says older women really aren’t disadvantaged on the dating market.
Ms Lowe was arrested last week after police received a tip, and is charged with sexual activity with a boy under the age of 16 and abusing a position of trust, She denied the charges, and her defending lawyer reportedly said she "wants to clear her name".
The prosecution said police had obtained diaries and text messages which showed Ms Lowe, who has separated from her husband, was “infatuated” with the alleged victim.
She believes — and I agree — that more people need to talk openly about this because all older women hear (and thus believe) is that older men are them from the 50-something dating pool ASAP; I’m not interested in men like that so move along, men, and good luck! As a newly single woman after an eight-plus year relationship, I am curious about what to expect this time, now that I’m 50-something instead of 40-something.
I, too, am not looking for a husband (although I’m not necessarily against marrying), but I most definitely would like a partner — uhh, with conditions.
Since heat flow in a large ice sheet is very slow, the borehole temperature is another indicator of temperature in the past.
