Title:Warming effects of spring rainfall increase methane emissions from thawing permafrost: Site-level data from bog complex II - Carex Metrics 2014-2016
Alternate Identifier:DOI PLACE HOLDER
Abstract:

Methane emissions regulate the near-term global warming potential of permafrost thaw, particularly where loss of ice-rich permafrost converts forest and tundra into wetlands. Northern latitudes are expected to get warmer and wetter, and while there is consensus that warming will increase thaw and methane emissions, effects of increased precipitation are uncertain. At a thawing wetland complex in Interior Alaska, we found that interactions between rain and deep soil temperatures controlled methane emissions. In rainy years, recharge from the watershed rapidly altered wetland soil temperatures, warming the top ~80 cm of soil in spring and summer, and cooling it in autumn. When soils were warmed by spring rainfall, methane emissions increased by ~30%. The warm, deep soils early in the growing season likely supported both microbial and plant processes that enhanced emissions. Our study identifies an important and unconsidered role of rain in governing the radiative forcing of thawing permafrost landscapes. All site-level data from the studied bog, eddy covariance and micrometeorological data referenced in the published manuscript are available in the LTER data repository. These data are related to the following data package: Surface carbon, water and energy fluxes measured by eddy covariance at 3 sites within the Alaska Peatlands Experiment and Bonanza Creek Experimental Forest 2013-2016 (http://dx.doi.org/10.6073/pasta/4fabab3846113a1866b06f1b3d6d52a3).

Methods and protocols used in the collection of this data package
Description:

Methods

All data were collected 2014 to 2016 from a thawing bog complex. Plant data were collected from gas flux collars at the edge and center of the bog during peak biomass (mid to late July). Each year, percent cover of Carex species was visually estimated. In 2014, stems of Carex were counted within five 8-cm by 8-cm subsections of collars and scaled up based on collar area, while in 2015 and 2016, stems were counted within entire collars. In all three years, heights of Carex species were measured relative to the bog surface within five 8-cm by 8-cm subsections of collars.
