Title:	Soil respiration from the Ice Storm Experiment (ISE) at the Hubbard Brook Experimental Forest
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	An ice storm simulation was performed at the Hubbard Brook Experimental Forest to evaluate impacts of these extreme weather events on northern hardwood forests. Water was pumped from the main branch of Hubbard Brook and sprayed above the forest canopy in subfreezing conditions so that it rained down and froze on contact with trees. The experiment included five ice storm intensities (0, 6.4, 12.7 and 19.1 mm radial ice accretion) applied in a single year, and one ice storm intensity (12.7 mm) applied in two consecutive years. Measurements of soil respiration were made with an infrared gas analyzer during the snow-free season before and after the ice was applied. 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.

Methods and protocols used in the collection of this data package

Description:

Soil respiration was measured with an infrared gas analyzer system (LI-8100A survey system; Li-Cor Biosciences, Lincoln, NE, USA). Measurements were made approximately fortnightly between the hours of 10:00 a.m. and 3:00 p.m. during the snow-free season. Two permanent PVC soil collars (20 cm (8 inch) diameter) were positioned randomly in four subplots within each plot (eight collars per plot). The rate of soil C efflux was calculated based on the increase in chamber CO2 concentration over 2 min. Soil temperature was measured at 5 cm soil depth using a soil probe for each reading. Additionally, measurements of air temperature and relative humidity were made within the chamber. The collar offset was measured to determine the headspace within the collar.
