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 (chrip) 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followed an earlier subbottom acoustic-reflection survey (1997), using boomer and 3.5 kHz systems (S. M. Colman, unpublished data).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:
The bathymetric contours will be used as a reference for depth information within Bear Lake, Utah-Idaho. No bathymetric surveys have been conducted in the Lake since the 1970's. This dataset represents the most up-to-date bathymetric information for the area.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
These data are internally consistent; all data were acquired with an SEA 2000 Series Submetrix interferometric sonar.
Logical_Consistency_Report:
These data are were checked for consistency by plotting the point data with the contoured surface and eliminating suprious and anomolous soundings.
Completeness_Report: These data are complete.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
All navigation data were acquired using the Wide Area Augmentation System (WAAS), a GPS-based navigation and landing system providing precision guidance to aircraft. Horizontal accuracy of the WAAS network is assumed to be accurate < 3 meters.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Vertical accuracy is dependant on the navigation system. All navigation data were acquired using the Wide Area Augmentation System (WAAS), a GPS-based navigation and landing system providing precision guidance to aircraft. The Wide Area Augmentation System (WAAS) is assumed to have a vertical accuracy of +/- 5 meters. All ship motion was recorded by a TSS DMS 2-05 Attitude Sensor.

Process_Step:
Process_Description:
Bathymetric data were corrected for variations in the speed of sound throughout the water column; sound velocity profiles were acquired at locations throughout the lake and throughout the survey period. Attitude sensor and compass information were incorporated into the header of the bathymetric data files using the SEA RTS2000 acquiistion and processing system. The resultant data files were imported into SEA GRID2000 program and gridded to a 10 meter grid cell size.

Process_Description:
The SEA GRID2000 file was then exported as x,y,z. The weighgrid command within the University of New Brunswick, Ocean Mapping Group, SwathEd software was used to interpolate the data to fill in between line data gaps. An interpolation of 300 meter radius was used.

Process_Description:
Edits to the metadata were made to fix any errors that MP v 2.9.32 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 link to the data in the Identification_Information section had to be fixed. The link to the data in the Distribution_Information section had to be added. The blank entity and attribute section was deleted. 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.
