Soviet ice drilling projects in Antarctica include decades of work at Vostok Station, with the deepest core reaching 3769 m.Numerous other deep cores in the Antarctic have been completed over the years, including the West Antarctic Ice Sheet project, and cores managed by the British Antarctic Survey and the International Trans-Antarctic Scientific Expedition.Radioactive elements, either of natural origin or created by nuclear testing, can be used to date the layers of ice.Some volcanic events that were sufficiently powerful to send material around the globe have left a signature in many different cores that can be used to synchronise their time scales.Cores are drilled with hand augers (for shallow holes) or powered drills; they can reach depths of over two miles (3.2 km), and contain ice up to 800,000 years old.

The lowest layer of a glacier, called basal ice, is frequently formed of subglacial meltwater that has refrozen.Ice cores are collected by cutting around a cylinder of ice in a way that enables it to be brought to the surface.Early cores were often collected with hand augers and they are still used for short holes.At Summit Camp in Greenland, the depth is 77 m and the ice is 230 years old; at Dome C in Antarctica the depth is 95 m and the age 2500 years.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.

Most of the time, California doesn’t get the national government we choose. Clearly California leans left but by the time of the 2016 election we will have had a Republican-controlled House for 19 out of the last 24 years and a Republican-controlled Senate for 15 out of the last 24 years. population is not from California, and that means in practice all these non-Californians decide what national government California gets.
