  • Abstract:

    All data on soil carbon flux (“soil respiration”) collected using chamber-based methods at Harvard Forest from a range of observational and experimental plots were collated, their units were harmonized, and geographic (locations) and environmental characteristics (soil series, drainage class, soil temperature, soil moisture, vegetation type, etc.) were identified for each observation. This yielded a dataset with 106,192 observations of soil respiration taken between 1991 and 2008. These data provide a unique resource for exploring spatial and temporal patterns in soil respiration in a range of common New England forest types.

    For the Giasson, et al. (2013) publication, we also used 24 site-years of eddy covariance measurements from two Harvard Forest sites (EMS and Hemlock towers) to examine the relationship between soil and ecosystem respiration. Here, we present all derived/synthetic datasets associated with the manuscript.

  • Methods:

    Methods are detailed in the Giasson, et al. (2013) Ecosphere publication. See original publications for methods for individual studies.

    All data are quality checked by individual investigators before submission to the data archive. Data was also quality checked upon compilation for appropriate ranges of values consistent with individual sites. For most sites, geographic coordinates, elevation, vegetation class, soil series and soil drainage class data were obtained using Harvard Forest Properties Maps (HF110) in ArcGIS v.9.3. For sites outside of the range of the soil series and soil drainage class maps, investigators were contacted to provide this information.
