The persistent belief is that women are looking for long-term committed relationship and men are looking for short-term sexual relationships.
That may be true for younger people, but that isn’t always the case at this age, she says.
The length of the record depends on the depth of the ice core and varies from a few years up to 800 kyr (800,000 years) for the EPICA core. the shortest time period which can be accurately distinguished) depends on the amount of annual snowfall, and reduces with depth as the ice compacts under the weight of layers accumulating on top of it.
Upper layers of ice in a core correspond to a single year or sometimes a single season.
The properties of the ice and the recrystallized inclusions within the ice can then be used to reconstruct a climatic record over the age range of the core, normally through isotopic analysis.
