  (updated 08-Feb-2017)
Project Title:Vulnerability of inland waters and the aquatic carbon cycle to changing permafrost and climate across boreal northwestern North America
Project Lead: Rob Striegl, USGS
Project Funding: 2015 - 2018
NASA (agency representative: Eric Kasischke)
Project Type:NASA -- joined ABoVE in 2015
Solicitation:NASA: Terrestrial Ecology (2014)
Abstract: Water is key to all ecosystem functions, including the carbon (C) cycle. Additionally, rates of C biogeochemical processing are commonly much greater in inland waters than terrestrial landscapes, as they collectively store C in sediments, export C to oceans, and emit carbon dioxide (CO2) and methane (CH4) to the atmosphere. Terrestrial ecosystems ... [more]
