New observatory offers a look at life's 'thin veneer'
Eco-hydrologist Greg Barron-Gafford shows how the gantry-crane basket works during a demonstration of the new Landscape Evolution Observatory at Biosphere 2. Researchers will use the basket to keep from walking on the testing beds.

The University of Arizona took over management of Biosphere 2 in 2007 and accepted ownership in 2011.

A few of the attendees walk under two of the three 40-by-100-foot test beds during a demonstration last month of the new Landscape Evolution Observatory at Biosphere 2.
Work under way in Biosphere 2 on 3 huge experimental slopes
An architectural rendering shows how the three slopes should look once finished in 2012.

A crane from Parsons Steel Erectors moves a support beam into place inside Biosphere 2. Big equipment had to squeeze into the glass structure.

Atop a beam, Nate McCollum of Parsons Steel Erectors works to attach a crossbeam for one of the new slopes inside Biosphere 2. The $7 million Landscape Evolution Observatory, or LEO, will help study how water moves through and across various landscapes. "This will be the largest earth science instrument ever built," said John Adams, assistant director of Biosphere 2.
Research is a half-billion-dollar annual enterprise at the University of Arizona. As the president and Congress trim the deficit, university researchers brace for funding cuts, attacks on winning proposals and ideological snipes at areas such as climate research.
