  • Description

    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.

    Annual datasets have been registered with the EarthChem Library and assigned dataset DOI’s. Please reference the associated DOI for any research derived from this data.
    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).

Data Use Policy
Data Sharing Policy
  • Data Use Policy

    DRAFT v.0.4.0

    1. Use our data freely. All CZO Data Products* except those labelled Private** are released to the public and may be freely copied, distributed, edited, remixed, and built upon under the condition that you give acknowledgement as described below. Non-CZO data products — like those produced by USGS or NOAA — have their own use policies, which should be followed.

    2. Give proper citation and acknowledgement. Publications, models and data products that make use of these datasets must include proper citation and acknowledgement. Most importantly, provide a citation in a similar way as a journal article (i.e. author, title, year of publication, name of CZO “publisher”, edition or version, and URL or DOI access information. See Also include at least a brief acknowledgement such as: “Data were provided by the NSF-supported Southern Sierra Critical Zone Observatory” (replace with the appropriate observatory name).

    3. Let us know how you will use the data. The dataset creators would appreciate hearing of any plans to use the dataset. Consider consultation or collaboration with dataset creators.

    *CZO Data Products.  Defined as a data collected with any monetary or logistical support from a CZO.

    **Private. Most private data will be released to the public within 1-2 years, with some exceptionally challenging datasets up to 4 years. To inquire about potential earlier use, please contact us.

  • Data Sharing Policy

    DRAFT v.0.2.5

    All CZO investigators and collaborators who receive material or logistical support from a CZO agree to:

    1. Share data privately within 1 year. CZO investigators and collaborators agree to provide CZO Data Products* — including data files and metadata for raw, quality controlled and/or derived data — to CZO data managers within one year of collection of samples, in situ or experimental data. By default, data values will be held in a Private CZO Repository**, but metadata will be made public and will provide full attribution to the Dataset Creators†.

    2. Release data to public within 2 years. CZO Dataset Creators will be encouraged after one year to release data for public access. Dataset Creators may chose to publish or release data sooner.

    3. Request, in writing, data privacy up to 4 years. CZO PIs will review short written applications to extend data privacy beyond 2 years and up to 4 years from time of collection. Extensions beyond 3 years should not be the norm, and will be granted only for compelling cases.

    4. Consult with creators of private CZO datasets prior to use. In order to enable the collaborative vision of the CZO program, data in private CZO repositories will be available to other investigators and collaborators within that CZO. Releasing or publishing any derivative of such private data without explicit consent from the dataset creators will be considered a serious scientific ethics violation.

    * CZO Data Products. Defined as data collected with any monetary or logistical support from a CZO. Logistical support includes the use of any CZO sensors, sampling infrastructure, equipment, vehicles, or labor from a supported investigator, student or staff person. CZO Data Products can acknowledge multiple additional sources of support.

    ** Private CZO Repository. Defined as a password-protected directory on each CZO’s data server. Files will be accessible by all investigators and collaborators within the given CZO and logins will be maintained by that local CZO’s data managers. Although data values will not be accessible by the public or ingested into any central data system (i.e. CUAHSI HIS), metadata will be fully discoverable by the public. This provides the dual benefit of giving attribution and credit to dataset creators and the CZO in general, while maintaining protection of intellectual property while publications are pending.

    † Dataset Creators. Defined as the people who are responsible for designing, collecting, analyzing and providing quality assurance for a dataset. The creators of a dataset are analogous to the authors of a publication, and datasets should be cited in an analogous manner following the emerging international guidelines described at
