SSHCZO -- Soil Porewater Chemistry -- Shale Hills -- (2006-2011)

OVERVIEW

Description/Abstract

Chemistry of soil water collected from 2006-2010 at four transects in the Susquehanna Shale Hills Critical Zone Observatory. Two transects were located on the Northern (N) side of the catchment while the additional two transects were located on the Southern (S) side. Each portion of the catchment then contained a Planar (P) hillslope and a Swale (S) depression transect. Three different topographic sites were sampled within each transect, the most elevated site was located at the Ridge Top (RT) followed by the Mid Slope (MS) and lowest site at the Valley Floor (VF). As the lysimeters were installed to the depth of auguring refusal, first lysimeters was installed at a depth 10 cm with subsequent lysimeters installed every 10 cm.

Comments

Soil water was collected using nested-suction lysimeters (Soil water samplers, 1900 series, SoilMoisture Equipment Corp., Santa Barbara, CA) that collected soil water 10 cm depth increments. All lysimeters were suctioned to 50 k Pa one week prior to sampling. Soil was collected from each lysimeters using PVC tubing and syringe. When possible, four unfiltered soil water samples were collected at each lysimeters. Two samples were collected in screw top Nalgene bottles for anion and cations. The additional two samples were collected in glass bottle and analyzed for dissolved organic carbon (DOC) and oxygen and hydrogen stable isotopes. Cations and DOC samples were acidified in the laboratory with nitric and hydrochloric acids, respectively.

Major cations and silica were analyzed on an inductively coupled plasma–optical emission spectrometer (ICP– OES), while major anions were measured on the Dionex Ion Chromatograph (Sunnyvale, CA). DOC was analyzed using a Shimadzu TOC-5000A analyzer (Shimadzu Scientific Instruments, Columbia, MD). Oxygen and hydrogen stable isotopes were analyzed ion the DLT-100 liquid water stable analyzer (Los Gatos Research, Mountain View, CA).
