Abstract:
In September and October of 2010, the U.S. Geological Survey (USGS), in cooperation with the Army Corps of Engineers (USACE), conducted geophysical surveys around Cat Island, Miss. to collect bathymetry, acoustical backscatter, and seismic reflection data (seismic-reflection data have been published separately, Forde and others, 2012). The geophysical data along with sediment vibracore data (yet to be published) will be integrated to analyze and produce a report describing the geomorphology and geologic evolution of Cat Island. Interferometric swath bathymetry, and acoustical backscatter data were collected aboard the RV G.K. Gilbert during the first cruise which took place September 7-15, 2010. Single-beam bathymetry was collected in very shallow water around the island aboard the RV Streeterville from September 28 through October 2, 2010 to bridge the gap between the landward limit of the previous cruise and the shoreline. The survey area extended from the nearshore to approximately 5 kilometers (km) offshore to the north, south, and west, and approximately 2 km to the east. This report archives bathymetry and acoustical backscatter data and provides information and mapping products essential for completion of the project goals. The bathymetry will provide elevations and show geomorphic characteristics of the seafloor, while the backscatter and acoustical backscatter imagery will enhance the geomorphic characteristics and give insight to variations of sediment types on the seafloor. This file contains the trackline locations and names of the single-beam bathymetry around Cat Island, Miss.
Purpose:
This file includes all survey tracklines for the single-beam bathymetry data collected around Cat Island, Miss. in September and October 2010 by the U.S. Geological Survey (USGS), St. Petersburg Coastal and Marine Science Center. It serves as the bathymetry part of an archive of data for the entire project.
Supplemental_Information:
Trackline files were recorded using HYPACK software during the survey.

Process_Description:
GPS acquisition: A GPS base station was erected within approximately 20 to 30 km of the survey area on a pre-existing National Geodetic Survey (NGS) benchmark at Point Cadet, Miss. GPS data were recorded using Ashtech Z-Xtreme GPS receivers that record the 12-channel full-carrier-phase positioning signals (L1/L2) from the satellites via the Thales choke-ring antenna. This GPS instrument combination is duplicated on the survey vessel (rover). The base receiver and the rover receiver record their positions concurrently at 1-second (s) recording intervals throughout the survey period.

Process_Description:
Trackline files were saved and exported from HYPACK and imported into ESRI ArcGIS 10 as point files. The point files were converted to line files, edited, and line names were added to the attribute field.

Horizontal_Positional_Accuracy_Report:
All static base station sessions were run through On-Line Positioning User Service (OPUS) maintained by the National Oceanic and Atmospheric Administration (NOAA) and the National Geodetic Survey (NGS). The base location results from OPUS were put in a spreadsheet to compute final values and error analysis. Using the OPUS values for each day and the total time that data were collected each day, the average weighted values were calculated for each day for latitude and longitude (so the longer occupation times held more value than the shorter times). The final value for latitude and longitude was used in GrafNav for the base station value. Error was calculated using UTM output from OPUS (to get error in meters) for each day and was calculated as the absolute value of the final value minus the daily value. For this survey, the maximum horizontal error for the base station used for processing the single-beam bathymetry was 0.6 cm. DGPS navigation for the swath survey used OmniSTAR HP with horizontal accuracy reported by the service as +/- 10 cm (95% of the time).
