NASA's Arctic-Boreal Vulnerability Experiment


Mack-01 Project Profile
  (updated 19-Oct-2016)
Project Title:Increasing fire severity and the loss of legacy carbon from forest and tundra ecosystems of northwestern North America
Project Lead: Michelle Mack, Northern Arizona University
Project Funding: 2015 - 2019
NASA (agency representative: Eric Kasischke)
Project Type:NASA -- joined ABoVE in 2015
Solicitation:NASA: Terrestrial Ecology (2014)
Abstract: Depth of burning of the soil organic layer (SOL) and resultant carbon (C) emissions from wildfire is an important component of net ecosystem C balance in the ABoVE Domain. The SOL sequesters the majority of ecosystem C in layers that can be hundreds to thousands of years old. Deeper burning could rapidly shift ecosystems across a C cycle threshold: ... [more]
