Abstract:
Bear Lake is a tectonic lake that has existed for at least several hundred thousand years. The lake basin is a relatively simple half graben, a spoon-shaped depression tilted toward the main fault on the east side of the lake. The U.S. Geological Survey, in cooperation with researchers from several universities, has been studying the sediments of Bear Lake since 1996. The general purpose of this effort is to reconstruct past limnological conditions and regional climate on a range of timescales, from hundreds of years to hundreds of thousands of years. This research relates to a variety of human concerns, including water usage in the Bear River basin. Past work has included several coring operations, a seismic-reflection survey, sediment-trap deployments, a barge-mounted drilling operation with the GLAD800 drill rig, and a variety of other studies.
The objectives of the September, 2002 operations, preliminarily reported here, were (1) to compile a detailed bathymetric map of the lake using swath-mapping techniques, in order to provide baseline data for a variety of applications and studies, and (2) to complete a sidescan-sonar survey of the lake, providing a nearly complete acoustic image of the lake floor. Limited amounts of subbottom acoustic-reflection data (CHIRP) were also collected, along with samples of lake-floor sediments representative of different kinds of backscatter patterns. These surveys followed an earlier subbottom acoustic-reflection survey (1997), using boomer and 3.5 kHz systems (S. M. Colman, unpublished data).
Purpose:
JPG images of each seismic line were generated in order to incorporate images of the seismic data into Geographic Information System (GIS) projects and data archives utilizing HTML. The JPG format is universal and enables hassle-free transfer of data. These data yield a pictoral view of the seismic data acquired.

Horizontal_Positional_Accuracy_Report:
WAAS (Wide Area Augmentation System) is assumed to be accurate within 1-2 meters. Standard GPS is assumed accurate within 5-10 meters. All WAAS data are referenced to WGS84. The data were acquired with an Edgetech 424 kHz CHIRP sub-bottom profiler. The system was towed at the surface, close to the survey vessel. Horizontal accuracy is thus assumed to be within +/-3 meters.

Process_Description:
Raw SEGY-Y data were processed utilizing Colorado School of Mines Seismic Unix (SU) seimsic processing software. The seismic data were recorded with TEI Delph Seismics acquisition software. Durinr processing, the SEG-Y data were converted to SU format. Gains were applied to the data to reduce noise and enhance the data. 'Mute' was used to remove all noise/signals within the water column. The data were then converted to postscript and JPG formats.

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). The larger work citation in the identification section was added. Added the online link to the zipped data file in the Identification_Information section. Added ISO 19115 Topic Category keywords. Modified the Distribution section to include the format and the link to the data. The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.
