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 […]
Jonathan Perez stands in a remote part of Alaska’s North Slope while White-Crowned Sparrows sing from surrounding shrubs and a Jaeger flies overhead, calling. Perez is listening to the bird calls, recording what species sound out and how many individuals are singing. Next to him, an automated device is attempting to do the same.
Even Wacky Weather doesn’t stop bird migration to Alaska. Scientists on the north side of the Brooks Range at Toolik Field Station find the birds which made it over the mountains have located their nests, indicating procreation has begun.
Vacuuming at home isn’t too edifying. How about vacuuming the Alaska tundra to snag a bag full of bugs? That’s an entirely different story. Ashley Asmus, graduate research assistant at the University of Texas at Arlington, is using a huge reverse leaf blower to collect the bugs she’ll study.
On the tundra a wire walk-in trap has been placed over seed scattered atop icy Alaskan ground. A Longspur alights nearby. It twists its head to eye the seed, hops inside then briefly flaps – unsettled by the trap door closing behind it. The Longspur settles and eyes the ground again, beginning to peck. PhD student Jesse Krause, a researcher […]
The Arctic is blanketed in snow for 9 to 10 months of the year. Then in May or June, with the Sun shining long overhead, snow melt comes sudden. Mathew Sturm, professor of Geophysics, University of Alaska, Geophysics Institute says the world of the Arctic can go from “White to dark in a space of […]
Laura Nielsen for Frontier Scientists – Jason Dobkowski stands on the shores of Wolverine Lake. His research site is located in the North Slope of Alaska, nestled near the remote foothills of the Brooks Range. “I’m here studying permafrost thaw slump which is depositing silt and material into the lake behind me. And that material, […]
Laura Nielsen for Frontier Scientists Sea ice is the foundation of an entire Arctic ecosystem. Algae flourishes where the ice is active, providing sustenance for hordes of zooplankton. Birds feed on schools of small fish sustained by the zooplankton. There are species of seabirds which live here and nowhere else, and others whose natural rhythms […]
As she scraped cold dirt from the remains of an extinct bison, Pam Groves wrinkled her nose at a rotten-egg smell wafting from gristle that still clung to the animal’s bones. She lifted her head to scan the horizon, wary of bears that might be attracted to the flesh of a creature that gasped its […]
Each spring, wildlife biologist Craig George stands where shore-bound sea ice meets open water at Point Barrow and counts whales. Barrow Alaska is the northernmost town in the united states. The lookout point, accessed daily via snowmobile, is no more than a canvas windbreak atop a pile of ice. Warming spring temperatures thin and break […]
Ned Rozell for UAFGI – HALL ISLAND — On this windy, misty August day, there are perhaps one million birds clinging to the cliffs that buttress this Bering Sea island. These seabirds, crazy-eyed and with bodies both sleek and clumsy, need solid ground for just a few months to hold their eggs. When their summer […]
Ned Rozell for UAFGI – With their mushroom clouds topped with cauliflower crowns, plumes from wildfire smoke are again a common sight in Interior Alaska, which — with barely a sprinkle of rain — just experienced one of the driest Mays in the 100-year written record. Though it’s a normal human reaction to think of […]
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 […]
In Alan Weisman’s book, The World Without Us, the author ponders “a world from which we all suddenly vanished. Tomorrow.” In last week’s column, a few experts discussed the fate of Alaska structures if Alaskans were to disappear. This week, people who study Alaska’s wildlife donate some thought to the subject. Alaska’s lack of people […]
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, […]
