An Alaska Army National Guard UH-60 Black Hawk helicopter from 1st Battalion, 207th Aviation Regiment, drops approximately 700 gallons of water from a “Bambi Bucket” on to the Stetson Creek Fire near Cooper Landing, Alaska, June 17. Two AKARNG Black Hawk helicopters flew a total of 200 bucket missions, dumping more than 144,000 gallons of water on the 300-acre Stetson Creek Fire on the Kenai Peninsula.

Measuring the Impact of Severe Fires in the Arctic

Ecoss researcher Michelle Mack is leading a $1 million NASA-funded project to measure the extreme fire activity in boreal forests and its effects on arctic tundra. Based on the number of acres burned, 2015 is shaping up to be the second most extreme fire year during the past decade in North […]

Integrating Ecosystem-Scale ’Omics in Microbial Communities.

Soil is a complex ecosystem with diverse microenvironments ranging from bulk soil with low quality substrates and no or very limited microbial growth, to high quality C-rich environments near decomposing litter and rhizosphere where microbial growth and death rates are high. Soil contains different microbial communities, supports varying microbial activities […]

Green microscopic microbes, both tubular and round.

The Role of Soil Processes in the Global Carbon Cycle

When new carbon enters soil, especially carbon that is easily assimilated and decomposed by soil microorganisms, a chain reaction occurs leading to the breakdown of older soil carbon, carbon that would otherwise have remained stable. Current theory does not explain this chain reaction, sometimes called the “priming effect.” But understanding […]
