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followed an earlier subbottom acoustic-reflection survey (1997), using boomer and 3.5 kHz systems (S. M. Colman, unpublished data).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: Sound velocity profiles were collected in order to map the sound velocity profile of the water column. The interferometric sonar systems acquires high-resolution bathymetric measurements in a swath. However, changes in the sound velocity profile with depth will affect the acousit ray path. The acoustic ray path must be accurately modeled in order to calculate accurate depth and position of individual soundings.

These locations are accurate within 3 meters (recorded WAAS horizontal accuracy). Logical_Consistency_Report: These data were all acquired with a Applied Microsystems Sound Velocity Profiler deployed off of the same platform. These data were collected throughout the survey area. Completeness_Report: These data are known to be complete. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: WAAS is assumed to be accurate within 1-2 meters. Standard GPS is assumed accurate within 5-10 meters. All data were recorded using the WAAS (Wide Area Augmentation System) navigation. All WAAS data are referenced to WGS84. All sample locations are assumed to be accurate to +/- 3 meters. Lineage: Process_Step: Process_Description: Sound Velocity profiles were collected throughout the study area to map the velocity structure of the water column. Changes in the speed of sound throughout the water column will affect the swath bathymetric data; outer beams will experience refraction. The SVP was deployed and sent to the lake floor. Upon retrieval, data were downloaded and placed into a Mircosoft Excel spreadsheet. The individual profiles within the MS Excel spreadsheet were plotted, copied from Excel, pasted as a 'New' file with Adobe Photoshop 6.0, and saved in JPG format. The tabular data were exported from the Excel spreadsheet to a text file. The USGS Mapgen PROJ command was used to convert latitude and longitude values to eastings and northings (UTM Zone 12, WGS84 ellipsoid). This file was imported into ArcView as a table. The table was then converted to a shapefile. The JPG images of the sound velocity profiles were then hotlinked to the sound velocity profile shapefile.

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.
