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followed an earlier subbottom acoustic-reflection survey (1997), using boomer and 3.5 kHz systems (S. M. Colman, unpublished data).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:
Sediment samples were collected in order to ground-truth the sidescan-sonar data. Differing backscatter regimes were selected to sample in order to map their surficial sediment character.

Attribute_Accuracy:
Attribute_Accuracy_Report:
Positions are accurate within +/- 3 meters (recorded WAAS horizontal accuracy).
Logical_Consistency_Report:
These data were all acquired with a Van Veen Grab Sample off of the same platform. These data were collected within two days.
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 datum. All sample locations are assumed to be accurate to +/- 3 meters.

Process_Description:
The samples were acquired with a Van Veen grab sampler. The position of each location was recorded using Coastal Oceanographics, Inc HYPACK Max. Latitude and Longitude values were converted to eastings and northings using USGS Mapgen PROJ command (UTM Zone 12, WGS84 Ellipsoid). The location file, listing longitude, latitude, eastings, northings, water depth at sample location, time, date and sample id, was then formated as an ArcView table. The table was imported into ArcView. A shapefile was generated from the table. Photographs of the samples were taken in the lab after cruise completion. JPG images of the grab samples were then hotlinked to sample locations within ArcView.

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.
