Many angles to decode frozen debris lobes

“Something chewed on the casing,” Margaret Darrow explained. “Probably a bear.” Blue chips were scattered from the cracked ABS pipe. Inside the casings that protect the holes drilled in and around frozen debris lobe -A there’s non-toxic propylene glycol. Propylene glycol, this brand a clear greenish liquid, prevents freezing – helpful for scientific instruments – […]

Temperamental machinery and FDL science

When the machinery mounted to the man-height pole announced “RTK initialized,” the scientists gave a cheer. It was late afternoon and the morning’s downpour had finally cleared. They were gathered in a sunny spot discussing what was still on the agenda for the day when the rover – the pole and its paramount differential GPS […]

Unmanned Aircraft: Arctic science & technology

Speeding over Arctic sea ice, small remote-controlled aircraft snag video footage and high-definition shots of endangered Steller Sea Lions in their natural habitat. Quiet and unobtrusive, the machines can serve as Special Op.s for researchers. Low-altitude remote sensing using Unmanned Aerial Vehicles (UAVs) has vast potential… and we’re only beginning to explore it. Gregory Walker, […]
