Forest soil:atmosphere fluxes of carbon dioxide, nitrous oxide and methane at the Hubbard Brook Experimental Forest, 1997- present

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. 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.
