Researchers developed a method that uses high-resolution satellite imagery and deep machine learning to double the mapped infrastructure of Alaska and more accurately project economic risks associated with permafrost thaw In the Arctic, permafrost plays a crucial role in building infrastructure. However, as the region warms and permafrost thaws, infrastructure is threatened as the ground […]
Tiny ocean wave vibrations from the Gulf of Alaska — too subtle for humans to notice — can travel through land as far north as Alaska’s Arctic coastline. These and other low-frequency vibrations generated daily by ocean waves offer insights into climate change. Research by doctoral student Sebin John at the University of Alaska Fairbanks […]
Civil War veteran Charles Raymond was 27 when he accepted an assignment to visit the new U.S. territory of Alaska, a place so far away from his home in New York City he couldn’t imagine it. Two years after Secretary of State William Seward had brokered the purchase of Alaska from Russia, U.S. leaders suspected […]
Winter’s sea ice extent in the Arctic set a new record low as it peaked March 22, according to the Alaska Climate Research Center’s monthly report. The report, released April 2, states the maximum sea ice for the season reached 5.5 million square miles. This is the lowest value in the satellite record, which began in […]
