Antarctic adventure for NIU scientists begins with test run in fabled depths of Lake Tahoe
Upcoming journey to ice-entombed lake will be no easy trek
Sep 10, 2012
Just after Christmas this year, NIU scientists Ross Powell and Reed Scherer, with colleagues from nine other major universities, will traverse more than 600 miles across the Ross Ice Shelf in Antarctica, braving potential crevasses and wind speeds as high as 100 mph along the way...
Over the past few weeks, researchers and engineers involved in the Antarctic expedition have been testing their custom-made scientific instruments from a barge anchored in the nation’s second deepest lake.
Several coring devices and other instruments were tethered to an above water bank of computers, providing for real-time data, and lowered into the lake via a crane on the barge.
“Despite some substantial winds that kicked up nearly every afternoon on the lake, the testing was very successful,” Powell says. “We now have a strong understanding about how the drill and science operations can be handled and integrated at our Antarctic field sites. We also learned how to tweak our instrumentation to collect reliable scientific data.”
