Why was the data set created?

How was the data set created?

1. From what previous works were the data drawn?

   Information unavailable from original metadata (source 1 of 1)

   U.S. Geological Survey, unknown, Information unavailable from original metadata.

   Type_of_Source_Media: disc
   Source_Contribution:

   Sidescan-sonar (acoustic-backscatter) data were acquired with a Klein 3000 dual-frequency sidescan-sonar system (100 and 500 kHz), which was towed approximately 3 m astern from a port-side davit. Klein SonarPro acquisition software was used to log the data digitally at a sample rate resulting in raw pixel resolutions of approximately 0.18 and 0.14 m in the across-track and along-track directions, respectively. Horizontal offset values between the sidescan fish and DGPS antenna were provided to SonarPro, which calculated fish position dynamically during acquisition. The Klein system produced useable data over swath widths of 150-m during cruise 2011-013-FA.

2. How were the data generated, processed, and modified?

   Date: 2011 (process 1 of 6)

   Navigation was extracted from the raw sidescan sonar data (*XTF format) at 1 minute intervals in XSonar (version: 2.0) using the 'demultiplex' function (Danforth and others, 1991). Navigation was exported as comma-separated text from XSonar for input into ArcGIS (version 9.3.1). Person who carried out this activity:

   In ArcCatalog (version 9.3.1), navigation text was converted to a point feature class by right-clicking on the comma separated text file -- Create Feature Class -- from XY table, and the projection was defined as UTM Zone 19N, WGS 84. Person who carried out this activity:

   The shapefile created in the previous step was used as an input for XToolsPro (version 7.1.0), which can convert point data to a trackline polyline shapefile based on record order. The 'Filename' field was used to define which points were used to generate each polyline feature. The length of each polyline segment was calculated by right-clicking on the newly created 'Length' attribute field and choosing 'Calculate Geometry'. This length calculation (in meters) was based on UTM, Zone 19N, WGS84. Finally, the file was reprojected to GCS WGS84 using ArcToolBox. Person who carried out this activity:

   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.). Added the DOI link in the Identification section - both as the first link and as part of the Larger Work citation. Fixed the publication date and also the Larger Work citation title to match what is available online. Updated the link to the project page in the abstract as well as the field activity links. The source information was incomplete and had to be modified to meet the standard. Fixed a link in the distribution section. 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. Person who carried out this activity:

How reliable are the data; what problems remain in the data set?

1. How well have the observations been checked?
   All attributes were checked in a consistent manner.
2. How accurate are the geographic locations?
   The navigation for these data were acquired with a Communications Systems International (CSI), Inc. LGBX Pro Differential Global Positioning System (DGPS) receiver and an antenna mounted on the cabin of the R/V Rafael. Unless noted, all DGPS data are referenced to WGS84. The horizontal distance (both x and y) between towed sidescan sonar fish and the mounted GPS antenna were measured on the ship and the correction was applied in the Klein SonarPro acquisition software. The differential GPS is accurate within 1 to 2 meters. The layback of the towfish adds additional uncertainty due to changes in angle and scope of the tow cable in response to sea state and vessel speed. The total horizontal uncertainty is + or - 10 meters.
3. How accurate are the heights or depths?
   
4. Where are the gaps in the data? What is missing?
   Navigation from all the Klein 3000 sidescan sonar tracklines from cruise 2011-013-FA was used to generate this shapefile. The Klein sidescan sonar was not operational (due to malfunction) for 5 lines near Martha's Vineyard on Julian Day 216.
5. How consistent are the relationships among the observations, including topology?
   Any spurious data points were removed during processing.
