NASA armada targets thaw in Arctic soil

On a 10-meter-square plot of frozen soil in central Alaska, Ted Schuur is creating a window to the future. Schuur, an ecologist at Northern Arizona University (NAU) in Flagstaff, is intentionally warming this patch of permafrost to see how much of its carbon— now locked in frozen plant matter buried […]

Tents at the Delta Campsite in Alaska

Webinar by Michelle Mack

Dr. Michelle Mack will be discussing the future vulnerabilities to Alaskan ecosystems and tools for permafrost assessment during the next resource conservation and resiliency webinar that will be hosted on Thursday, June 29! The webinar is part of the SERDP and ESTCP webinar series, which was launched to promote the […]

Importance of lateral flux and its percolation depth on organic carbon export in Arctic tundra soil: Implications from a soil leaching experiment

Temperature rise in the Arctic is causing deepening of active layers and resulting in the mobilization of deep permafrost dissolved organic matter (DOM). However, the mechanisms of DOM mobilization from Arctic soils, especially upper soil horizons which are drained most frequently through a year, are poorly understood. Here we conducted […]

Biochar boosts tropical but not temperate crop yields

Biochar, a fine-grained carbon residue of charred plant material, has recently been promoted as a universal amendment to soil to improve moisture and nutrient content with the expectation of higher agricultural yields, fostering the rise of a large global biochar industry.  In the original context of “terra preta,” the rich […]

The economic value of grassland species for carbon storage

Ecoss research demonstrated that grasslands with more diverse plant species pull down and store more carbon per acre: in this illustration, the same plot of soil from a diverse vs.  depauperate grassland shows more belowground investment in deeper roots and denser storage of carbon in a diverse array of plants. […]

The economic value of grassland species for carbon storage

In a groundbreaking study, Ecoss research produced a monetary value for biodiversity by demonstrating that having more diverse plant species enables a grassland to draw down and store more carbon.  This finding allows calculations of how much carbon storage is lost or gained per species added or lost from a […]
