Sea otter UAV health checkup

Spying on sea otter activities lets biologists measure populations of other species in the otters’ habitat. “It’s just a lot of work to get densities of clams and marine species like that,” described wildlife biologist Daniel Monson. To get a better idea of ecosystem health, scientists can use Unmanned Aerial Vehicle (UAV) technology to take […]

UAVs trail building potential sea ice maps

Trail building potential with UAV maps

“Breaking ice: it’s a community effort where a large amount of ice is leveled by the use of only hand tools,” said Eyal Saiet. Trail building off Barrow’s shore happens every spring. “It can be more than a month’s effort of breaking trail, so anything that can help breaking trail is of value.” “Sea ice […]

Hovering UAVs over sea otters

“Do you want lots of kelp forests? Than you want sea otters in your system.” “A kelp forest is a forest; it’s like you’re flying through a redwood forest.” Brenda Konar, professor in marine biology at the University of Alaska Fairbanks School of Fisheries and Ocean Sciences, both dives and teaches divers to handle cold […]

New videos about Frozen Debris Lobes, geohazards

February 24 2015— Slow landslides in permafrost slide downhill on mountain slopes in the Brooks Range of Alaska. These massive frozen debris lobes are geohazards. They pose a potential threat to the Dalton Highway, Alaska’s lone road to the North Slope. There are 23 identified frozen debris lobes situated less than one mile uphill from […]

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 – […]

Effective stress and FDL science

“It’s a very dynamic slope,” Margaret Darrow said, standing in front of frozen debris lobe -A. FDL-A is a slow landslide; among the frozen debris lobes documented it’s the closest to the Dalton Highway and the Trans-Alaska Pipeline. Although the lobes likely began their life as debris left over when Pleistocene glaciers disappeared 10 to […]

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 Aerial Vehicles (UAV’s) Fly in the Aleutians

August 14, 2012— Three videos detail the Unmanned Aircraft work from the University of Alaska Fairbanks (UAF). In March, Greg Walker, UAF’s Unmanned Aircraft Program Manager, led research in the Aleutians. Walker flies the UAVs in just about all conditions except freezing rain which would stick to delicate equipment. “We’ve regularly flown in showers, we’ve […]

Flying machines for the dirty, dull and dangerous

Some places in this world are just too dirty, dull or dangerous for human pilots to fly. An airspace in the latter category is anywhere near gas flares in Alask’s oil fields. With only a few seconds of warning, flames blast high in the air from a network of pipes, releasing the stress of sucking […]

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, […]
