How do landslides impact the carbon balance of Southeast Alaska?
The Tongass National Forest in Southeast Alaska is the greatest carbon reserve in North America, capturing carbon from the atmosphere and storing it in plants and soil. But natural and human disturbances, like erosion and logging, affect carbon stocks by moving organic material out of the forest, into streams and eventually coastal waters.

Backcountry enthusiasts take to the slopes to improve snow models
For scientists collecting data deep in Alaska’s backcountry, there are few access roads and even fewer weather stations to be found. There are, however, dedicated winter recreationists traversing the landscape by ski, snowshoe, and snowmachine. These backcountry enthusiasts are being recruited by scientists to contribute to a growing dataset of snow depth observations that are improving our understanding of snow distribution in remote locations.

Juneau students work with ACRC scientist to measure water quality
A steady curtain of rain falls over the banks of the Mendenhall River, but you’d never know it from the high spirits of Thunder Mountain students who have been working in the drenching conditions for over an hour. The students collect water samples in chest-high waders, armed with small vials and temperature probes. A group onshore inspects sediment and invertebrates collected from the stream bed. They are part of an ongoing program led by science educators Adriana Northcutt and Kristen Wells to engage eleventh- and twelfth-grade biology students in studying the Mendenhall watershed and impacts of water quality on salmon habitat.

Dead trees could bring new life to southeast Alaska lumber mills
As climate change rapidly alters conditions in southeast Alaska, lower snowpack levels have caused a massive decline of yellow-cedar trees. Without an insulating blanket of snow, the shallow roots of yellow-cedar trees freeze during late spring cold snaps. Left behind is a growing expanse of “ghost forests” of dead yellow-cedars, affecting roughly 678,000 acres (nearly the area of Yosemite National Park). The decay-resistant properties of yellow-cedar allow the trees to remain standing for decades after death. ACRC director Allison Bidlack, and collaborators Brian Buma, Sarah Bisbing, and Brian Vander Naald, set out to determine whether these ghost stands might provide an economic opportunity for small lumber mills in Tongass National Forest.

Paralytic shellfish toxins spike amidst new research
Shellfish harvesters and beachcombers wandering the shores around Juneau might have made an odd discovery this summer– a small white hunk of plaster under the water, strapped to a neatly labeled brick. These contraptions are part of an effort to better monitor and predict paralytic shellfish poison (PSP) levels, which were almost ten times higher this summer than at any time in the last three years.

Can yellow-cedar recover from climate-driven declines?
Across the temperate rainforest of Southeast Alaska, a change is taking root. Warming winters are reducing snowpack in the region and causing a massive decline in a culturally, economically, and ecologically important tree species; yellow-cedar. Yellow-cedar trees are adapted with fine, shallow roots that allow them to respond to early spring warming and get a head start on growth over other species. Once an advantageous adaptation, it has now made the species susceptible to freezing when early snowmelt and frosts can be fatal to mature yellow-cedar trees. In Alaska and British Columbia, yellow-cedar is declining across 400,000 hectares and ten degrees of latitude.

Unique drainage event at Suicide Basin causes minor flooding in Juneau
As smoke from distant wildfires clouds the skies above Southeast Alaska, Juneau residents have a much closer hazard on their minds. Warm weather sped up water collection in Suicide Basin, a glacier-dammed lake adjoining Mendenhall Glacier that has generated outburst floods regularly over the last decade. On Sunday, July 7th, the basin water level reached a point where it began to overtop the Mendenhall Glacier ice dam, flowing along the side of the glacier towards Mendenhall Lake. Almost one week later, on July 13th, the basin began draining beneath the glacier. At Mendenhall Lake, the water level rose to 8.62 feet (just under minor flood stage) and peaked just after 8 P.M. – earlier and lower than predicted.

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.
