Seismic data collected during this survey can help to define the rates of deposition within the San Juan and Colorado Rivers, which are the main inflows to Lake Powell. These new data are intended to improve water budget management decisions that affect the natural and recreational resources of the reservoir. Multibeam echosounder bathymetry and backscatter data were collected along 2,312 kilometers of tracklines (331 square kilometers) of the lake floor to regionally define its depth and morphology, as well as the character and distribution of lake-floor sediments. Ninety-two kilometers of seismic-reflection profile data were also collected to define the thickness and structure of sediment deposits near the confluences of the San Juan and Colorado Rivers. Purpose: This dataset contains 500 shot point navigation and unique shot point navigation for approximately 92 km of chirp seismic-reflection data collected by the U.S. Geological Survey during survey 2017-049-FA along the San Juan Arm and Good Hope Bay to Hite sections of Lake Powell in the Glen Canyon National Recreation Area. This information allows for spatial correlation of chirp seismic-reflection profiles images with other geophysical and sample data for investigating lake-floor morphology and stratigraphy in the area.

Browse_Graphic_File_Type: JPEG Native_Data_Set_Environment: Microsoft Windows 7 Version 6.1 (Build 7601) Service Pack 1; Esri ArcGIS 10.3.1.4959 Data_Quality_Information: Logical_Consistency_Report: Chirp seismic-reflection profile data were collected continuously along the San Juan River between 16:35 and 22:47 (UTC) on 10/12/17 (JD285) and the Colorado River between 15:52 and 19:07 on 10/17/17 (JD290). Line numbering in the San Juan section begins with l1f1.001 and ends with l1f5.001. Line numbering in the Colorado section begins with l2f1 and ends with l2f2.001. There is a starting shot point (1) and ending shot point (x) with even 500-shot intervals in the shapefile for each seismic trackline. The CSV file contains unique shot point navigation. No duplicate navigation fixes exist for multiple shots. The attribute field 'ImageName' lists the PNG profile image included in "2017-049-FA_Edgetech424_Images.zip" (available from the larger work citation) that corresponds to each line. Seismic profiling was conducted only at these locations to investigate sediment accumulation near the confluences of the rivers with Lake Powell. Completeness_Report: Sections of tracklines where navigation was recorded but no seismic data were logged are not included such as during testing, some turns, and very short files. There is no line l1f1. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The EdgeTech SB-424 subbottom profiler was towed from a port side davit on the R/V Stephens with the transducer approximately 1 m below the water line, and 2.8 meters astern of the DGPS antenna mounted atop the port side of the cabin. Navigation data for the SB-424 were collected using a Hemisphere Differential GPS (DGPS) receiver. Positioning data were recorded using Edgetech Discover Sub-Bottom (version 4.04) acquisition software, which logged positioning coordinates to individual trace headers SEG-Y format. DGPS horizontal positional accuracy is assumed to be within 2 m; the layback position of the transducer relative to the DGPS antenna was accounted for during processing.

Edgetech Discover Sub-Bottom (version 4.04) seismic acquisition software was used to control the 3100 topside unit, digitally log trace data in the SEG-Y Rev. 1 format (IEEE floating point), and record GPS navigation coordinates to the SEG-Y trace headers (in arc seconds of Latitude and Longitude, multiplied by a scalar of 100). Data were acquired using a 250 milliseconds (ms) shot rate, a 10-ms pulse length, and a 4 to 20 kHz frequency sweep. Traces were recorded with a 23-microsecond sample interval over lengths of approximately 236 ms. Process_Step: Process_Description: PROCESS STEP 1: SIOSEIS (version 2015.3.1), OpenCPS (version 3.3.0), and Seismic Unix (version 4.2) were used to process SEG-Y data, create navigation files, and plot images. The processing flow and scripts used to produce navigation files including trackline shapefiles are summarized below and in the following processing steps. 1) SIOSEIS was used to read the raw SEG-Y files, extract the envelope-detected trace, renumber shots starting from one, and write out new SEG-Y files. 2) OpenCPS was use to run the following flows: A) read_segy.flow - SegyTapeRead read the traces. HeaderMath and UTMLatLong were used to convert the source lat/lon positions from seconds of arc to decimal degrees, project them to UTM Zone 12N WGS 84 meters, and write each to new header words (NRP_LAT, NRP_LON, NRP_X, and NRP_Y). DBWrite wrote the UTM positions for the first channel of each FFID to an internal OpenCPS database table. Finally, Output wrote the traces to a new file "*.sht-raw.seis" in the internal OpenCPS format. B) layback_shift.flow - Input read the "*.sht-raw.seis" file and sorted the traces to FFID/CHANNEL. The custom Python module ShotlineLayback (developed by Nathan Miller of USGS-WHCMSC) was used to define the measured horizontal offset between the DGPS antenna and the SB-424 transducer (-2.8 m). The algorithm interpolated a sail line from the source shot positions (NRP_X and NRP_Y), then computed layback positions for the SB-424 shots by translating them back along the sail by the measured offset. ApplyStatic was used to shift the traces down by 1.35 ms to account for the approximate 1 m tow depth of the SB-424 (the sound speed of 1480 m/s, a typical value observed from SVP profiles during the survey, was used to convert the depth in meters to 2-way travel time in ms). Output wrote the shifted traces to a new SEG-Y files in which the trace header words SRC_X, SRC_Y represent the calculated layback coordinates, and REC_X, REC_Y maintain the original DGPS coordinates. 3) The SIOSEIS script Read424 was used to read layback and static corrected SEG-Y files, write a Seismic Unix file, and extract SEG-Y trace header information, including shot number, pre-layback and layback longitude and latitude, year, Julian day, and time of day (UTC). Header information from each SEG-Y file was saved to text files after an AWK (no version) filter was used to maintain the first and last shots, shots at multiples of 100, 500, and shots with unique navigation coordinates. Geographic coordinates (WGS 84) were converted to UTM zone 12 N coordinates (WGS 84) using Proj (version 4.6.0). End shots and shots at multiples of 100 may not have unique navigation coordinates. Separate text files containing the first and last shots and even 500 shot intervals were also saved. A 500 shot interval was chosen because it corresponds to the annotation interval provided along the top of the seismic-reflection profile images. Read424 called a Python script 424toSQL17049.py, written by Wayne Baldwin, which imported the CSV files to a Spatialite (version 4.3.0) enabled SQLite (version 3.21.0) database, creating two tables containing point geometries for the unique and 500 shot interval navigation. These process steps and all subsequent process steps were conducted by the same person - Wayne Baldwin.
