Hubbard Brook Experimental Forest: Soil-atmosphere fluxes of carbon dioxide, nitrous oxide and methane on Watershed 1 and Bear Brook

Soil atmosphere fluxes of the trace gases; carbon dioxide (CO2),
nitrous oxide (N2O) and methane (CH4) have been measured at several
locations at the Hubbard Brook Experimental Forest (HBEF) including 1)
the “freeze” study reference plots that provide contrast between
stands dominated (80%) by sugar maple versus yellow birch and low and
high elevation areas, 2) the Bear Brook Watershed where trace gas
sampling is coordinated with long-term monitoring of microbial biomass
and activity and 3) watershed 1 where trace gas sampling locations
were co-located with long-term microbial biomass and activity
monitoring sites that are located near a subset of the lysimeter sites
established for the calcium addition study on this watershed. This
dataset contains the Watershed 1 and Bear Brook data. Freeze plot
trace gas can be found in:

These data were gathered as part of the Hubbard Brook Ecosystem Study
(HBES). The HBES is a collaborative effort at the Hubbard Brook
Experimental Forest, which is operated and maintained by the USDA
Forest Service, Northern Research Station.
