Geospatial_Data_Presentation_Form: raster digital data Series_Information: Series_Name: U.S. Geological Survey Data Series Issue_Identification: 291 Publication_Information: Publication_Place: Florida Publisher: U.S. Geological Survey Online_Linkage: http://pubs.usgs.gov/ds/291/ Description: Abstract: This data set contains swath bathymetric data collected during USGS cruise 06FSH01 aboard the R/V G.K. Gilbert. A side scan sonar, bathymetric, and high-resolution seismic-reflection survey was conducted off Sarasota, FL to describe the relationship between the sediments and morphology of the inner shelf and adjacent shoreface. These data are part of the Florida Shelf Habitat (FLaSH) map project. For more information on the seismic surveys see http://walrus.wr.usgs.gov/infobank/g/g106fl/html/g-1-06 -fl.meta.html These data are also available via GeoMapApp (http://www.geomapapp.org/) and Virtual Ocean ( http://www.virtualocean.org/) earth science exploration and visualization applications. Purpose: Part of an offshore site survey using high resolution geophysical mapping (seismic, side scan, and singlebeam bathymetery) techniques as part of the Florida Shelf Habitat (FLaSH) map project. More information at http://coastal.er.usgs.gov/flash. Supplemental_Information: In May of 2006, the U.S. Geological Survey conducted a geophysical survey offshore of Siesta Key, FL, as part of the USGS Florida Shelf Habitat (FLaSH) study, a multiagency benthic habitat mapping project. For more information refer to http://coastal.er.usgs.gov/flash/index.html. This report serves as an archive of the processed side scan sonar mosaic, processed singlebeam and swath bathymetry images, processed x,y,z swath bathymetry data, trackline maps, navigation files, GIS files, Field Activity Collection System (FACS) logs, observer's logbook, and formal FGDC metadata. Scanned images of the handwritten FACS logs and handwritten science logbook (12 MB) are also provided as PDF files. Gridded and interpolated surface digital images of the bathymetry are also provided. Refer to the Acronyms page for expansion of acronyms and abbreviations used in this report.The USGS Florida Integrated Science Center (FISC) - St. Petersburg assigns a unique identifier to each cruise or field activity. For example, 06FSH01 tells us the data were collected in 2006 for the Florida Shelf Habitat (FLaSH) study and the data were collected during the first field activity for that project in that calendar year. Refer to http://walrus.wr.usgs.gov/infobank/programs/html/definition/activity.html for a detailed description of the method used to assign the field activity ID.Aboard the R/V G.K. Gilbert, side scan sonar and interferometric swath bathymetry data were collected simultaneously along the tracklines. The side scan sonar towfish was towed behind the vessel close to the seafloor. The interferometric swath transducer was pole mounted to the ship's hull. See the digital FACS equipment log (13 KB) for details about the acquisition equipment used. Both raw data sets were stored digitally and processed using CARIS software in the St. Petersburg office. For more detailed information on processing refer to the Equipment and Processing page. Post-processing of the swath data set revealed a motion artifact which is attributed to movement of the pole in relation to the boat. Due to scheduling constraints, the survey was forced to take place in less than ideal weather conditions, which caused a reduction in data quality. The rough seas contributed to both the movement of the pole and the very high noise base seen in the amplitude data.In addition, singlebeam bathymetry was collected aboard the R/V Streeterville using SANDS, which is a singlebeam acoustic sounding GPS-based hydrographic data collection and processing system. Differential boat position was recorded using GPS referenced to a land-based benchmark which is occupied throughout the survey. Boat position, boat motion (heave, pitch, and roll), and depth readings are collected and stored in real time on the vessel and are later merged with the DGPS information using time correlations. For more detailed information on processing refer to the Equipment and Processing page. CHIRP data were also collected during the survey and are archived separately in Data Series 254 and can be downloaded at http://pubs.usgs.gov/ds/2007/254.

All data were acquired with a SEA, Ltd. SWATHplus interferometric sonar. Postprocessing of the swath data set revealed a motion artifact which is attributed to movement of the pole in relation to the boat. Due to scheduling constraints, the survey was forced to take place in less than ideal weather conditions, which caused a reduction in data quality. The rough seas contributed to both the movement of the pole and the very high noise base seen in the amplitude data.

Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The ship was navigated with DGPS using two antennas and integrated OmniSTAR/Seastar differential correction. Unless noted all DGPS data are referenced to WGS84 (NAD 83). The fathometer is mounted on the starboard side of the vessel. Offset between the sonar head and the DGPS antenna were measured, and the horizontal accuracy of bathymetric data is within +/- 1-2 m. Motion of the fathometer is not measured. Quantitative_Horizontal_Positional_Accuracy_Assessment: Horizontal_Positional_Accuracy_Value: 1-2 m +/- Horizontal_Positional_Accuracy_Explanation: assumed accuracy of DGPS Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Ship motion was measured using a CodaOctopus F190 motion sensor and gyro with dual frequency GPS and integral satellite differential receiver. The interferometric sonar is an angle-measuring system; depth accuracy decreases with increasing horizontal range. The swath width of the interferometric sonar varied as a function of depth but generally achieved 7- 10 times the water depth. Vertical accuracy is directly affected by the accuracy of both the navigation system and tidal measurements. Lineage: Process_Step: Process_Description: The raw Submetrix data (SXP files) were processed using CARIS HIPS and SIPS v-6.0. A single value sound velocity profile was applied using 1,538.0 m/s. A tide correction was applied using verified tidal data from the NOAA station at Clearwater Beach, FL (#8726724), and referenced to Mean Lower Low Water (MLLW). The Swath Editor within the HIPS package was used to edit the data on a ping-by-ping basis, in both the across- and along-track dimension. Spurious or erroneous data were removed. The navigation and attitude data were also graphically examined for each line of data. The HIPS software was used to create a BASE surface similar to a weighted grid at 5-m grid cell size. The 5-m gridded data were then exported to an x,y,z ASCII file.

An ordinary kriging interpolation was used in order to generate a continuous bathymetric surface from the interferometric sonar data. This surface was exported to raster using a default cell size of 32. This file is named raster_cell32.
