Distributed Acoustic Sensing Experiment Data from Garner Valley, California

Description

In September 2013, an experiment using Distributed Acoustic Sensing (DAS) was conducted at Garner Valley, a test site of the University of California Santa Barbara (Lancelle et al., 2014). This submission includes all DAS data recorded during the experiment. The sampling rate for all files is 1000 samples per second. Any files with the same filename but ending in _01, _02, etc. represent sequential files from the same test. Locations of the sources are plotted on the basemap in GDR submission 481, titled: "PoroTomo Subtask 3.2 Sample data from a Distributed Acoustic Sensing experiment at Garner Valley, California (PoroTomo Subtask 3.2)."

57 This is an ambient noise zip file containing multiple 30 second segments of data from an 8 hour block of overnight recording. The local (PDT) start time of these files is 18:58:50 and the end time of this zip file is 21:11:04. No active sources were used during these tests, though passing traffic is seen in the data. https://gdr.openei.org/files/614/ambient_noise_2.zip

The local (PDT) start time of these files is 21:11:05 and the end time of this zip file is 23:23:15. No active sources were used during these tests, though passing traffic is seen in the data. https://gdr.openei.org/files/614/ambient_noise_3.zip
57 This is an ambient noise zip file containing multiple 30 second segments of data from an 8 hour block of overnight recording. The local (PDT) start time of these files is 23:23:16 and the end time of this zip file is 01:35:30 the following day. No active sources were used during these tests, though passing traffic is seen in the data. https://gdr.openei.org/files/614/ambient_noise_4.zip
57 This is an ambient noise zip file containing multiple 30 second segments of data from an 8 hour block of overnight recording. The local (PDT) start time of these files is 01:35:31 and the end time of this zip file is 01:56:05. No active sources were used during these tests, though passing traffic is seen in the data. https://gdr.openei.org/files/614/ambient_noise_5.zip
57 This file is a zip file containing all cable mapping tests. Each data file is at most 30 seconds in length. These tests were recorded using repeated hammer blows on a steel plate at 13 locations around the array. The location is given in the filename. https://gdr.openei.org/files/614/CM_all_tests.zip
57 This file is a zip file containing all tests during which the DAS system was set up to use. During this file, the system would likely have recorded passing traffic. https://gdr.openei.org/files/614/traffic_all_tests.zip
57 This file is one zip file containing multiple tests from a 27 kN swept source. The source swept from 20 to 100 Hz over 10 seconds. The location is given in the filename. https://gdr.openei.org/files/614/VibroTruck_All_Files.zip

57 This file represents up to 30 seconds from one test of a 45 kN swept source on top of a structure. The source swept from 0 Hz, up to 10 Hz, and back down to 0 Hz over 60 seconds, followed by a three second listening time. https://gdr.openei.org/files/614/Large_Shaker_All_Files.zip
