New videos: Brant, carbon and climate in the Y-K Delta

In Alaska’s Yukon Delta National Wildlife Refuge scattered ponds and twining rivers dot the landscape. Here in the remote Yukon-Kuskokwim Delta (Y-K Delta) researchers tackle five months in the field. New Frontier Scientists videos feature their work gathering information about our shifting climate, investigating the implications of mismatched natural events.

Carbon dioxide, geese and greenhouse gasses

“The effects of climate change are are really complex,” and “There are a number of changes that are happening together that are going to ultimately affect how ecosystems operate,” Kathy Kelsey, postdoctoral researcher at the University of Alaska Anchorage, told Frontier Scientists. Kelsey and colleagues are studying changes in the Yukon-Kuskokwim Delta (YKD) of western […]

Pondering the infinite in Yukon Flats

YUKON FLATS — Out here, in a smooth plain stretching over Alaska’s wrinkled face, water and tree and mud dissolve to fuzz at each horizon. No hills or bumps. An ocean of sky. An observer once said Yukon Flats looks like a place where God forgot to put something. Garrett Jones and I are camped […]

Geese mowing the climate lawn

“It’s amazing that these little two-pound birds running around the Delta can have such a large impact,” Ryan Choi told Frontier Scientists. Pacific black brandt wing their way to western Alaska every year. There, these geese are influential players in their ecosystem, impacting vegetation, carbon cycling, and greenhouse gas emissions. Ryan Choi, PhD student at […]

“Doing science in the Delta is more than just coming up with interesting questions and implementing them. It also requires a lot of on-the-ground work and pre-season preparation in order to be out here for as long as we are.” A five month field season in remote Alaska is no deterrent to Ryan Choi. “I […]

Biologist creates legacy at village goose camp

When Craig Ely thumbed through his collection of photos of Alaska Native kids and biologists gathered in front of an old church, he knew he had to make a yearbook. Not for himself, though he would savor the memories, but for all the kids who had helped him do science since the 1980s. The U.S. […]
