Lysimeter chemistry from the Ice Storm Experiment (ISE) at the Hubbard Brook Experimental Forest

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. Samples of soil solution chemistry were collected with
lysimeters throughout the year 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.
