At the height of summer in 2021, Ned accompanied University of Alaska Fairbanks ecologist Ben Gaglioti to a ghost forest a glacier had run over in Southeast Alaska. Ned and Ben spent about two weeks near La Perouse Glacier, the one that ran over the trees during a cold period called the Little Ice Age. The story begins with the pair standing on a lonely beach about 100 miles south of Yakutat after a bush pilot dropped them off. (28:10)

Permafrost researcher Vladimir Romanovsky, professor emeritus at the Geophysical Institute, reflects on his career and surprising changes to Alaska's permafrost during his 30-year career. This episode is part 2/2 of  a conversation with Romanovsky starting in the previous episode . (38:51)

Vladimir Romanovsky is retiring after 30 years of studying permafrost at UAF's Geophysical Institute. He enters professor emeritus status while seeing changes in Alaska's frozen ground he never anticipated when scientists spoke of a new ice age in the 1970s. Romanovsky talks about why these discoveries of rapidly thawing ground are hard on roads and houses built over permafrost — frozen ground that has survived the heat of two summers — but are fascinating to him as a researcher. Part 1 of 2.

Bird biologist Dan Ruthrauff of the USGS Science Center in Anchorage describes the bar-tailed godwit, a bird that every fall flies from Alaska to New Zealand without stopping. That’s a week to nine days straight in the air!

Hannah Myers is a graduate student and a killer whale linguist. She has listened to hundreds of underwater recordings from which she can identify distinct families of whales. Myers and other researchers found that killer whales hang offshore of the Gulf of Alaska even during winter, when salmon are no longer headed for their birth streams.

Martin Truffer is a glaciologist at the University of Alaska Fairbanks Geophysical Institute. He reports that the Malaspina Glacier is more than three thousand feet deep in some places, describes how his research group is monitoring its progress and speculates about future changes to this massive glacier in Southcentral Alaska.
