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 […]
It’s hard to imagine stalking the shores of Alaska hunting with spear or net more than four millennia ago. Harder still to know that the people living in that already-harsh time faced an even more insidious threat than hunger or the fierce elements. New archaeological findings show elevated levels of toxic mercury in Pacific Cod […]
If you know where to look in the Arctic, you’ll find strange hexagons dotting the tundra beneath the enduring summer sun. Strange, scattered honeycomb chambers. The open-top hexagonal units shelter 1 or 2 square meters’ worth of tundra plants, passively raising the temperature within their fiberglass walls by 1-3°Celcius.
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.
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, […]
Liz O’Connell for Frontier Scientists – Multiple instruments, configured along a tram-like platform, sense the tundra below and gather detailed data while traveling along a 50 meter transect. “We are gathering measurements that we don’t know exactly how they will be used,” said Steven Oberbauer, professor of biological sciences at Florida International University. The high […]
In Alaska’s North Slope snow can be called overeager. Scientists at Toolik Field Station know that —except for the second half of August— they can expect it to snow any day of the year. Even during the brief summer, fierce storm fronts sometimes bring snow that melts away in 70°F (21°C) weather the very next […]
Ned Rozell for UAFGI – Despite taking up as much space as Australia, the blue-white puzzle of ice floating on the Arctic Ocean is an abstraction to the billions who have never seen it. But continued shrinkage of sea ice is changing life for many living things. A few Alaska scientists added their observations to […]
Laura Nielsen for Frontier Scientists – Plants, evolved to move with the natural rhythms of the world, cannot keep up with the rapid pace of climate change we are facing today. Their ideal habitats are sliding north as the world heats up. Do we get our hands dirty and help move the species most at […]
Laura Nielsen for Frontier Scientists – On a remote island in Norway, deep within an old coal mine sealed behind blast doors, seeds sit in the cold and quiet and wait. They are an insurance against an uncertain future. Our uncertain climate future is altering habitats so swiftly that plants can’t keep up, and we’re […]
Laura Nielsen for Frontier Scientists – Arctic temperatures are warming at twice the rate of lower latitudes’, making the area one of the most rapidly changing regions on Earth. Arctic ecosystems are facing radical alteration. And, surprisingly, a tiny furry rodent may be a major player in those changes. Lemming populations have a powerful impact on […]
Laura Nielsen for Frontier Scientists – There’s a new Titanic under construction: a grandiose ocean liner, maiden voyage set for 2016. The Australian billionaire undertaking the project intends Titanic II to be a near-perfect replica of the original RMS Titanic, the ill-fated steamship which sank in 1912 after striking an iceberg. The disaster claimed over 1,500 lives. […]
Laura Nielsen for Frontier Scientists The Arctic hosts a complex ecosystem, sensitive to the alterations in our changing world. Algae is part of that biome, growing in strands which hang down from the edge of ice floes. New conditions have caused an explosion in the growth rate of the algae Melosira arctica, which will influence […]
Imagine yourself on a Colorado mountain slope. Bumblebees buzz happily around dwarf bluebell blossoms, and the spring sun is bright. Except not all is well. The flowers bloom a good seven hundred feet upslope of where they grew five years ago, forcing bees ever higher. Bright petal colors are faded: the flowers are past their […]
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 […]
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 […]
