An art science collaboration starts today on the Ross Ice Shelf. 99 blue spheres varying in size from ten inches to four feet across represent the stars as of 2006-12-22.
This temporary monument with about 800 feet in diameter is conducted by internationally renowned artist Lita Albuquerque of Los Angeles and funded by the National Science Foundation and US Antarctic Programme.
This ephemeral artwork will be a major extension of her commitment to develop a visual language that addresses the realities of time and space.

Not far away near Mt. Erebus an international science team managed to drill through 100m of ice shelf, 900m of water and more than 1000m into the seabed. The deepest hole ever drilled in Antarctica tells the story of a dynamic Antarctic ice sheet advancing and retreating more than 50 times during the last five million years.
By Christmas at 1200m depth, the researchers will be able to review seven million years of climate and geological history. First analyses shows some evidence of collapses in shelf’s past. As known from the Larsen A + B shelfs a full collapse may happen within a few days.
The Ross Ice Shelf, big as France, performs an important function by slowing down the flow of glacial ice. If the ice sheets go away, many scientists believe that glaciers will flow more swiftly, adding their ice to the oceans, and that could cause sea level rise. nzherald.co.nz: Antarctic drilling record
