Notes on the oil and gas fields of Webb and Zapata counties : the underground position of the Austin formation in the San Antonio oil fields
Cockpit resource management at USAir
The current USAir CRM program is presented. The lessons learned and the program issues are combined. The training material was developed after an extensive literature search and pilot interview survey to determine the problem. The investigation led to the design, implementation, and evaluation of a behavioral science awareness training program. The need was found, and the target population was identified as the pilot group

Geologic map of the New Braunfels, Texas, 30 x 60 minute quadrangle : geologic framework of an urban-growth corridor along the Edwards Aquifer, south-central Texas
Process Steps: 1. Either: a) a Portable Document Format (PDF) version of the map provided the Bureau of Economic Geology, University of Texas at Austin was converted from pdf to Tagged Image File Format (TIFF) or b) a paper map was scanned and saved in TIFF at 200 dots per inch (dpi) and the original map size. The TIFF file was then opened in Adobe Photoshop, converted from RGB or other multiband mode to Indexed Color or Grayscale, rotated so that the top map neat line was horizontal, set to 200 dpi, and clipped to the neat lines, removing the map collar. A version with the map collar was retained. 2. Using tools within ArcGIS 10.2, both the collared and collarless Indexed Color TIF images were then either: a) georeferenced to Universal Transverse Mercator (UTM) zone 14, North American Datum 1927 (NAD27) coordinates using a digital 1:24,000 U.S. Geological Survey quadrangle index map from the Texas Natural Resources Information Services as the referencing layer or b) georeferenced to World Geodetic System 1984 (WGS84) geographic coordinates using the map corner coordinates for reference. Keyhole Markup Language (KML, KMZ) and GeoPDF map versions were created from these georeferenced maps by tools and export options in ArcGIS.
Up to five different georeferenced versions of the original map and, when available, the map pamphlet, are available for download. The versions, as distinguished by Download File name, are: 1) Mapname.pdf: a GeoPDF of the collarless map referenced to UTM zone 14 coordinates relative to the NAD27 datum. The acronym "GAT" (Geologic Atlas of Texas) indicates the source and a map original available only at a small scale (1:250,000). 2) Mapname.kmz: a KML version of the collarless map for viewing in Google Earth. The spatial reference is geographic coordinates relative to the WGS84 datum. 3) Mapname_GCSWGS84_collarless.zip: zipped files that include a collarless map in TIFF format and ancillary ArcGIS v. 10.2 georeferencing files and metadata. The spatial reference is geographic coordinates relative to the WGS84 datum. 4) Mapname_UTM_collarless.zip: a zipped file that includes a collarless map in TIFF format and ancillary ArcGIS v. 10.2 georeferencing files and metadata. The spatial reference is UTM zone 14 coordinates relative to the NAD27 datum. 5) Mapname_with_collar.zip: the same as above but with the map collar still intact. 6) Mapname_pamphlet.pdf: a copy of the map pamphlet in PDF format.
Any file name beginning with "GAT" indicates a map that was clipped from the Geologic Atlas of Texas (scale 1:250,000), the only published source for that area, and thus a much smaller-scale map than all other quadrangles.
Further metadata for each map version are available in Federal Geographic Data Committee (FGDC)-compliant metadata file within the zip files, or in the document properties of the GeoPDF and KML files when opened in Adobe Acrobat or Google Earth.Includes geologic cross-section and stratigraphic column."For use by Barton Spring Edwards Aquifer Conservation District (BSEACD) Central Texas geologic mapping project"Portion of a scanned and georeferenced version of Collins, E.W., 2000, Geologic Map of the New Braunfels, Texas, 30x60 Minute Quadrangle: University of Texas at Austin, Bureau of Economic Geology, Miscellaneous Map MM-39, scale 1:100,000.UT Librarie

Clastic Sinkhole and Pseudokarst Development in East Texas
Pseudokarst development in East Texas is controlled primarily by a combination of suffosion and preferential flow paths, often creating small ephemeral sinkholes but occasionally persistent features develop in more indurated facies. Pseudokarst occurs in Claiborne (Eocene) strata in Angelina, Cherokee, Nacogdoches, Panola, Rusk, San Augustine and Shelby counties. Strata consist of interbedded fine- and coarse-grained clastics with variable cementation and associated permeabilities
