Hubbard Brook Experimental Forest: Chemistry of freely-draining soil solutions in Watershed 6, 1984 - ongoing

Alternate Identifier:

DOI PLACE HOLDER

Abstract:

Tension-free lysimeters were installed in three soil horizons at three locations adjacent to Hubbard Brook Experiment Forest Watershed 6. At each location lysimeters were placed beneath the Oa horizon and within the upper and lower B horizon. Soil solution samples were collected approximately monthly and analyzed for pH, acid neutralizing capacity (ANC), base cations, soluble anions, trace metals, nitrogen and carbon.

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.

LOCATION DESCRIPTION

Tension-free lysimeters are installed in the Oa, Bh and Bs horizons at 3 sites located adjacent to watershed 6 at elevations of 750m (spruce-fir-white beech zone; SFB), 730m (high elevation hardwood zone; HH) and 600m (low elevation hardwood zone; LH). Three replicate lysimeters were installed beneath the Oa and Bh horizons and within the Bs horizon at the HH and LH sites, and two replicate lysimeters were installed in each horizon at the SFB site.

SAMPLING DESIGN

The lysimeters were constructed from either polyethylene funnels filled with acid-washed silica sand that drain into 1-L polyethylene containers or rectangular polyethylene containers filled with acid-washed Teflon beads that drain into 2-L polyethylene bottles. At each site, lysimeters were carefully installed in the wall of excavated soil pits, immediately below the Oa and Bh horizons and within the lower Bs horizon. Soil pits were backfilled to prevent accumulation of water and to eliminate freezing during winter months. Soil solution samples are collected approximately monthly in acid-washed polyethylene bottles and refrigerated at 4 degrees C.

NOTES ON DATA

Between 1984 and 1986 and 1998-present, data are the arithmetic means for samples collected from individual lysimeters. From 1986 through 1998, data are for bulked soil solutions collected from replicate lysimeters. Current detection limits for the Driscoll laboratory: Na (0.015 umol/L), K (0.12 umol/L), Ca (0.030 umol/L), Mg (0.0032 umol/L), Alt (0.0026 umol/L), Altm (1.3 umol/L), Alom (1.3 umol/L), NH4 (0.55 umol/L), H4SiO2 (3 umol/L), Cl (0.55 umol/L), NO3 (0.85 umol/L), SO4 (0.53 umol/L), F (0.097 umol/L), DIC (20 umol/L), DOC (20 umol/L), TN (0.81 umol/L). It is suggested to dataset users to use a value of one half the detection limit when a value for a solute is less than the detection limit. The data is physically located at the Department of Civil and Environmental Engineering, Syracuse University, Syracuse, NY.

Data correction in July of 2024: wherein 2009-2011 inorganic monomeric aluminum was inadvertently reported as organic monomeric aluminum (Alom), wherein 2012-2020 inorganic monomeric aluminum was inadvertently reported as total monomeric aluminum (Altm), wherein a date previously displayed as “9/15/2108” was changed to “9/15/2018” in Watershed 6 Lysimeter data. All errors have been corrected and the datasets have been updated to reflect the change.

“Alt” data represents Total Aluminum. “Altm” data represents Total Monomeric Aluminum. “Alom” data represents Organic Monomeric Aluminum.
