  1. National Soil Survey CenterSoil Survey Laboratory Data Webinar • Steve Monteith • Rick Nesser • Steve Baird • Henry Ferguson January 12, 2012 1-212-287-1661 Passcode CFISK Please do not put your phone on hold for ANYreason during the teleconference. Unless you intend to talk to all of us, use *6 or the mute button during the teleconference.

  2. Today’s Webinar will address three aspects of SSL data : • Data associated with sample submission • Data produced by sample analysis • Storage, maintenance and distribution of existing data.  

  3. Soil Survey Lab Data Creation, Maintenance, and Retrieval • There are data from over 49,000 samples in the NCSS database. Without complete and accurate descriptive data (metadata), the analytical data cannot be utilized. • There is an increased demand for data from internal users and from new classes of external users. • Metadata elements in the NCSS database are in need of update. This will require input from local soil scientists who have the specific knowledge and skills to do this. • New lab data is expensive and time consuming to acquire, but is essential to soil survey projects at whatever the cost. The expense necessitates complete and accurate sample documentation.

  4. Data associated with Soil Samples LIMS - Laboratory Information Management It manages: • Metadata submitted with samples describes Project, Site, Pedon, Layer, Samples • Analytical data created in the SSL • Output of Lab Data with associated metadata: Characterization data, Web site queries, CDs

  5. Part 1: Information Needed for Soil Sample Submission and Processing • A spreadsheet and checklist for submitting samples will be available on soils technical references web page: • http://soils.usda.gov/technical/

  6. Organization of Metadata in LIMS • Project (associated with all pedons and samples submitted) • Site (geographically associated with samples) • Pedon - Description (from NASIS, not Pedon PC) • Layer - Sampling zone, usually a horizon. There can be more than one layer per horizon. • Sample - Represents a layer. There can be multiple samples from a layer.

  7. Project Level Information • Submitter’s (your) contact information • SSL Liaison or project coordinator • Contacts to receive lab data and correspondence • Project description: Objective, parent material, setting, topography… (Will be used in selecting needed analyses.) • Date when data is needed • List of samples including sample types, horizon nomenclature and depths, fragment content. (SSL Sample Submission Worksheet) • Analyses requested for each sample

  8. Site Information • Location: lat – long in degrees, minutes, seconds if possible. Include datum. • Area overlap tables - MLRA, soil survey area code, state, county • This information must be in your NASIS pedon description.

  9. Pedon Information • Hard copies of pedon descriptions from NASIS pedon report. (Sample log-in area at SSL does not have NASIS) • Control section upper and lower depth. • Series name and / or taxonomic class. Pedon and site naming convention: (from Field Book for Describing and Sampling Soils ver 2.0):

  10. User Pedon and User Site ID • Example: S2004WA027009 • S = Indicates sampled pedon. • 2004 = Calendar year sampled. Use four digit format. • WA = Two-character (alphabetic) Federal Information Processing Standards (FIPS) code for state where sampled. For non-US samples, use FN. • 027 = Three-digit (numeric) FIPS code for county where sampled. It is important that this be the actual county (not the soil survey area) where the samples are taken to ensure compliance with APHIS regulations. • 009 = Consecutive pedon number for calendar year for county. This should be a three digit number. • A one-character ‘satellite’ code can be used if needed, e.g. S2004WA027009A • Do not use spaces, dashes or hyphens. Use 0 place holders when necessary . Use upper case letters. • Use the same ID for the User Pedon ID and User Site ID if possible. A spreadsheet for submitting samples is available at http://soils.usda.gov/technical/

  11. Pedon / Site information • Include an accurate list of NASIS User Pedon IDs and record IDs for all pedons in the project. The SSL will find these and make a copy of each pedon and assign that pedon to the “Pedons” group owned by the SSL. In the future, output of lab data will be associated with your NASIS pedon / site information. You will make any needed edits directly to your NASIS pedon. This will replace the SOI-8 process.
