    Comments
    Stream samples were collected as grab samples on a weekly basis and additional grab samples were collected before and after (within 24 hr) storm events. During storm events, samples were collected more frequently using automatic samplers (model-6712, Teledyne ISCO, Lincoln, NE, USA). Automatic samplers were programmed to collect samples on a 15-min interval or 30-min interval, depending on storm forecast. Threshold values were programmed before storm events based on current stage, previous stage behavior and future storm forecast. All samples were collected in 1-L Teflon® bottles previously washed in a 10 percent hydrochloric acid solution and rinsed three times with high-purity deionized (DI) water. Grab sample bottles were rinsed three times with streamwater before collecting a sample. Within 24 hrs of sample collection, samples were filtered using a 0.45 μm (47-mm) membrane filter (Pall Laboratory, VWR International LLC, Radnor, PA, USA) and the filtered water was parsed into separate bottles (rinsed three times with filtered sample water) individually tailored for preservation requirements according to specific constituent analysis. Samples for δ18O were collected unfiltered with no headspace in 20-mL borosilicate glass bottles with a poly-seal cone liner cap wrapped in parafilm to prevent evaporation and isotopic fractionation. Samples for anions were collected in 20-mL high density polyethylene (HDPE) bottles. Samples for dissolved organic carbon (DOC) were collected in 40-mL amber-colored borosilicate glass bottles (previously heated to 500°C for 4 hr). Samples for inductively coupled plasma optical emission spectrometry analysis were collected in 125-mL HDPE bottles pre-washed in an acid solution and the pH was lowered using a 1 percent (volume per volume) concentrated trace-metal grade HNO3. All samples were stored in the dark and refrigerated at 4°C until analysis. For quality assurance, duplicates and blanks (using DI water) were run approximately every 10 samples. For more information on sample preservation techniques, refer to McCleskey et al. (2012). Major cations and trace metals were determined using inductively coupled plasma optical emission spectrometry (ICP–OES, PerkinElmer 7300 DV) analysis at the USGS in Boulder, CO, with an accuracy of 1% and precision of 6%. Major anions were determined using ion chromatography system (model Dionex DX 600, Thermo Fisher Scientific, Waltham, MA, USA), with an accuracy of 9% +/- 2% standard deviation (SD) and precision of 6% +/- 4% SD. δ18O were analyzed using wavelength-scanned cavity ringdown spectroscopy with a L2120-i Isotopic Liquid Water Analyzer (Picarro Incorporated, Santa Clara, CA, USA), with a mean accuracy of 0.09 ‰ +/- 0.08 SD and a mean precision of 0.06 ‰ +/- 0.01 SD. DOC concentrations were determined using wet oxidation method with an Oceanography International Model 700 TOC Analyzer at the USGS Analytical Trace Elements Chemistry Laboratory in Boulder, CO, with an accuracy and precision <5%. Samples were analyzed for pH in the field using a portable pH meter (Orion Star A221, Thermo Fisher Scientific, Waltham, MA, USA) that was calibrated before every sampling event. Samples not analyzed for pH in the field were analyzed in the lab on 8/14/19 using the same pH meter.

  • 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 http://www.datacite.org/whycitedata). 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 http://www.datacite.org/whycitedata.
