The California Division of Mines and Geology (CDMG) selected the San Bernardino area for detailed geothermal resource investigation because the area was known to contain promising geothermal resource sites, the area contained a large population center, and the City of San Bernardino had expressed serious interest in developing the area's geothermal resource.

SUMMARY: This report presents the results of a cooperative study of geothermal systems in the region from Aurora, Nevada, and Bridgeport, California, south to Long Valley, California, by the Division of Mines and Geology and the Division of Earth Sciences of the University of Nevada, Las Vegas. The study is the initialreconnaissance phase of a project that was proposed to span several years. Magmatic and hydrothermal systems have been common in this region for the last 15 million years. The objectives of this study were to begin determination of the properties ~nd interactions of these systems and to develop hypotheses on the locations of undiscovered, active systems _in the region. SpeCial emphasis was given to the re~ional relationships and controls of the systems. New data presented include a Bouguer gravity map of the region, several gravity and magnetic profiles, a resistivity profile near Aurora, and a potassium-argon date on Mud Spring volcano, also near Aurora. New interpretations are presented regarding relative 8Qes and distributions of thermal fluids, gravity anomalies, d~pths to pre-Cenozoic: basement, structural controls of the geothermal systems, and the late Cenozoic tectonic-magmatic evolution of the region. The U.S. Department of Energy provided most of the funds for this project.

This addendum report presents the results of the California Division of Mines and Geology (CDMG) drilling program at Calistoga, California, which was the final geothermal-resource assessment investigation performed under terms of the second year contract (1979-80) between the u.s. Department of Energy (DOE) and the CDMG under the State Coupled Program. This report is intended to supplement information presented in CDMG's technical report for the project year, "Resource Assessment of Low-and Moderate-Temperature Geothermal Waters in Calistoga, Napa County, California."

The Reviewing Data for Online Delivery webinar covers topics on data delivery problems, the use of the templates and specifics about their worksheets, a brief review of the Identifiers and URI’s, and a review on the metadata for the data sets. The webinar also includes an overview of the geochemistry template. The AZGS takes a look at the new face of the State Geothermal Data website and its features.

This spreadsheet is a compilation of Aqueous Spring Chemistry observations compiled by the Arizona Geological Survey, published as a Web feature service for the National Geothermal Data System. The document contains 15 worksheets, including information about the template, notes related to revisions of the template, Resource provider information, the data, a field list (data mapping view), An Analyte Dictionary and a worksheet with vocabularies for use in populating the spreadsheet (data valid terms). Data from 116 springs are included.

This report provides a compilation of geothermal well and spring information in Arizona up to 1933. This report and data base are a part of a larger congressionally-funded national effort too encourage and assist geothermal direct-use. In 1991, the U.S. Department of Energy, Geothermal Division (DOE/GD) began a Low-Temperature Geothermal Resources and Technology Transfer Program. Phase 1 of this program includes updating the inventory of wells and springs of then western states and placing this data into a digital format that is universally accessible to the PC.

A brief overview on how to link data, obtain Identifiers, a look at the actual data and templates, and how to get your borehole data online. Video's part 1 - 5 Part 1 introduces and explains types of data for boreholes with an explanation on identifiers and linking data. Part 2 briefly explains metadata vs. data with an overview on templates used for borehole data. Part 3 takes a look at actual data being used and made through templates, spreadsheets and feature services. Part 4 starts off where part 3 stopped, a look at the actual data using the templates and feature services. Part 5 explains how to search the catalog for metadata records.

A brief overview on creating metadata records for resources in the US Geoscience Information Network (USGIN) and getting them in the system catalog. The catalog should include records for individually retrievable resources that are considered as a unit— things that come bundled in an individual file, document, or container. Software applications and services are also resources that should be documented in the catalog. Domain specific description information should be provided in domain-specific services like OGC feature or observation services or NetCDF services. Resources that would be provided by such ‘data’ services include individual database records, polygons in a GIS dataset, individual chemical analyses, and individual temperature measurements. Three workflows are currently supported by the system. The first is for situations in which there is some metadata information already compiled in a structured form that can be converted to a table for manipulation in a spreadsheet or database. Existing metadata should be loaded into the metadata template spreadsheet (http://www.stategeothermaldata.org/data-delivery/content-models/metadata/), and any missing information that can be added can be entered in the spreadsheet. The second workflow is for situations in which the metadata record must be created from scratch. There are two online tools for creating metadata in this situation. If the resource is already accessible online, the metadata wizard (http://mw.usgin.org/) provides forms for generating the metadata record. If the resource needs to be placed in a web accessible repository, the USGIN repository (http://repository.usgin.org/) is available to create a metadata record and upload the resource to make it available for online access. The AASG geothermal data project has implemented an online catalog using the open-source ESRI Geoportal software (http://catalog.usgin.org/geoportal). This catalog software has functions to harvest metadata from OGC service GetCapabilities documents, providing another path to get service metadata into the catalog. Includes webinar audio/video

This spreadsheet indicates the content requested for AASG geothermal data compiled from logs acquired in boreholes. The compiled data will be used to produce metadata records describing logs as resources of interest. Typcially bottomhole temperatures are recorded from log headers, and this information will be provided through a borehole temperature observation service. The HeaderURI for a particular borehole (well for simple wells) is the cross-referencing link (foreign key) used to associate the header record, well logs, temperature measurements, and other information from a particular borehole.
