Is glacier tourism changing the chemistry of the Juneau Icefield? ACRC supported graduate student wins National Geographic Society grant to find out.

Visiting graduate student Megan Behnke spent her last summer in Juneau deep in the mud, looking at how dissolved organic matter moves from wetlands into streams. This summer, she has something a few degrees cooler in store. Behnke was awarded a prestigious National Geographic Early Career Grant to investigate ancient carbon and the impacts of fossil fuels from tourism on the Juneau Icefield.

Dim Future: Black carbon and dust are speeding up glacial melt on the Juneau Icefield

Are tiny, heat-absorbing particles accelerating the melt of the Juneau Icefield? A recent study led by UAS Assistant Professor of Geology and ACRC collaborator Sonia Nagorski found that dust and black carbon particles darkening the snow surface are speeding up snowmelt on the Icefield by days, or even weeks each year. The study also included UAS faculty Eran Hood and Jason Fellman, Susan Kaspari from Central Washington University, and McKenzie Skiles from the University of Utah.

What does drought look like in Southeast Alaska?

The term drought brings to mind cracked earth, forest fires, and empty river beds, but at the Southeast Alaska Drought Workshop held in Juneau this week, a different type of drought was discussed.

By Rope, Raft, and Air: A season of research on glacier-dammed lakes

Rappelling down rock cliffs, rafting across glacial lakes, and traversing icy crevasses, all in the presence of a massive, ever-changing glacier – it's all part of the job for glaciologists monitoring glacial outburst floods (also known as jökulhlaups) in Alaska.

Thinking Deep: Land, sea, and soil connections at the Coastal Rainforest Margins Research Network Workshop

In March, over 30 scientists from across the US, Canada, and as far as Germany stood on the soggy wetlands of Juneau’s Douglas Island during the third Coastal Rainforest Margins Research Network workshop.

Salmon density exacerbates low dissolved oxygen in Southeast Alaska streams

Stand above a salmon spawning stream in Southeast Alaska come late summer, and the sheer quantity of fish is impressive. Maneuvering through water sometimes barely higher than their gills, salmon are powerful ecosystem engineers that disturb sediment and fertilize rivers. This fall, a study published in Aquatic Sciences led by ACRC researchers Jason Fellman, Eran Hood, and Sonia Nagorski looked at how salmon may be changing the chemistry of streams they travel in.
