Water is strangely warm in parts of the North Pacific: in the Gulf of Alaska, off Southern California, and stretching across the Bering Sea. A NOAA Northwest Fisheries Science Center press release reported: Not since records began has the region of the North Pacific Ocean been so warm for so long. That references over a […]
Instruments made to measure currents tug against their moorings on the sea floor. Others bob and whirl, catching currents, winds and tides with their rectangular wings spread just under wavetops in the Bering Strait west of Alaska. Ocean water is on the move. “There’s a strong connection between the world’s ocean currents and what comes […]
June 21 2015 was this year’s Summer Solstice. But for much of Alaska the long hours of sunlight were obscured by smoke. The Sockeye Fire near Willow Alaska started Sunday and raged, burning over 7,000 acres, forcing evacuations, ravaging homes and other structures and interrupting traffic on the Parks Highway. An admirable firefighting effort involving […]
During high school when the day promised heat I used to spend a minute in the morning to put sunglasses on my car. They were ‘shutter shades’, louvered sunglasses printed in bold lines on folded white cardboard meant to be spread just under the windshield. The car may not have contained power anything, a reliably […]
“They do their best to approximate a sphere,” Loren Buck explained as he removed the ground squirrel from its lab-made hibernaculum. Hibernating Arctic ground squirrels can sustain a core body temperature of just -2.9°C [26.78°F]. “It’s cold… Do you want to touch it?” Buck uncurled the animal carefully. “He knows he’s being handled, it just takes a […]
At Atigun River, north of the Arctic Circle, the sandy soil is run through with an interlaced network of burrows. The Arctic ground squirrels which call those burrows home have encountered something mundane to you or me, but no-doubt wondrous to them: big tasty taproots, stunningly orange. Carrots! Trapping squirrels The carrots are bait, placed […]
They survive colder core body temperatures than any other known vertebrate, sustaining a temperature below freezing yet not becoming frozen. They emerge from hibernation with clock-like accuracy
There’s a place where the perennially frozen ground of the Alaskan tundra is interrupted by 2 square miles [~ 5 km² ] of thawed soil. There, cottonwoods and thick brush grow among lazily meandering waterways. The Pilgrim Hot Springs are a pleasant symptom of the geothermal heat which warms the earth deep beneath Alaska’s Seward […]
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.
Azara Mohammadi – To become a PhD candidate at the University of Alaska Fairbanks, Soumik Basu moved from his home in Kolkata, India to a region infamous for its “below zero” weather: Interior Alaska. Basu left warm weather and his family (not to mention his mother’s cooking) because “The climate is changing, so I wanted […]
Laura Nielsen for Frontier Scientists – This winter snowy owls were on the move; unusually large numbers of the magnificent birds made their way to the Lower 48 United States. With a wing span greater than four feet and distinctive plumage, snowy owls are a glorious sight. The birds’ winter migrations normally take them to […]
Laura Nielsen for Frontier Scientists – The year 2013 was the fourth warmest year on record, according to the National Oceanic and Atmospheric Administration’s National Climate Data Center. 2013 tied with 2003 in NOAA’s record, which details global average temperatures all the way back to the year 1880. NOAA notes: “Including 2013, 9 of the […]
Laura Nielsen for Frontier Scientists – Recent research published in Nature Geoscience states that the largest contributors to warming in the Arctic are the region’s distinct surface temperatures coupled with the Arctic atmosphere’s prevailing vertical temperature structure. The research suggests that diminished snow and melting ice cover, previously thought to have the largest impact on […]
Laura Nielsen for Frontier Scientists – Wildfires are a hungry, terrible and complex force which we’ve long struggled to live alongside. Smoke and particulate matter from wildfires can travel thousands of miles, lowering air quality and causing health impacts. Local fires risk lives, and fire damage costs millions or more to repair. And now, conditions […]
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 In September 2012, at the end of last summer, the Arctic sea ice extent reached a record low since satellite measurements began. And, according to the National Snow and Ice Data Center, summer sea ice extent in the Arctic has declined roughly 40 percent in the last three decades. The […]
Laura Nielsen for Frontier Scientists The ozone hole is a problem which plagues the skies above Antarctica. Yet in 2011, Arctic skies experienced the most severe ozone depletion ever measured in the north. The reasons why are now explained in a paper published in the Journal of Geophysical Research-Atmospheres headed by lead author Susan E. Strahan, an atmospheric scientists […]
Laura Nielsen for Frontier Scientists Researchers have combed through the last 2,000 years of climate records. Their assessment affirms that a persistent long-term cooling trend concluded in the late 19th century, reversed by global warming. The study was performed by members of the “2K Network” of the International Geosphere Biosphere Program (IGBP) Past Global Changes […]
Laura Nielsen for FrontierScientists The face of the Arctic is changing as plant growth flourishes further north than before. According to the National Aeronautics and Space Administration (NASA), “Temperature and vegetation growth at northern latitudes now resemble those found 4 degrees to 6 degrees of latitude farther south as recently as 1982.” This change accompanies […]
Ned Rozell for UAFGI – This just in: 2012 was the coldest year of the new century in Fairbanks, and the second coldest here in the last 40 years. Fairbanks isn’t the only chilly place in Alaska. Average temperatures at 19 of 20 long-term National Weather Service stations displayed a cooling trend from 2000 to […]
Alaska was once the setting for an environmental shift so dramatic it forced people to evacuate the entire North Slope, according to Michael Kunz, an archaeologist with the Bureau of Land Management. About 10,000 years ago, a group of hunting people lived on the North Slope, the swath of mostly treeless tundra that extends north […]
Ned Rozell for UAFGI – Northern sea ice is at its lowest extent since we’ve been able to see it from satellites. Greenland experienced its warmest summer in 170 years. Eight of 10 permafrost-monitoring sites in northern Alaska recorded their highest temperatures; the other two tied record highs. 2012 was a year of “astounding” change for much […]
Kristin Knight Pace for Frontier Scientists – The brittle cold of Dead Dog Flats is enough to make my parka crinkle as I ladle out the hot mixture of fat and tripe, chicken protein and kibble. One by one the dogs emerge from their houses and, by the time I have gone through the whole […]
The permafrost monitoring network in the polar regions of the Northern Hemisphere was enhanced during the International Polar Year (IPY), and new information on permafrost thermal state was collected for regions where there was little available. This augmented monitoring network is an important legacy of the IPY, as is the updated baseline of current permafrost […]
