Abstract:
In order to test hypotheses about groundwater flow under and into Chesapeake Bay, geophysical surveys were conducted by U.S. Geological Survey (USGS) scientists on Chesapeake Bay and the Potomac River Estuary in September 2006. Chesapeake Bay resource managers are concerned about nutrients that are entering the estuary via submarine groundwater discharge, which are contributing to eutrophication. The USGS has performed many related studies in recent years to provide managers with information necessary to make informed decisions about this issue. The research carried out as part of the study described here was designed to help refine nutrient budgets for Chesapeake Bay by characterizing submarine groundwater flow and discharge of groundwater beneath part of the mainstem and a major tributary, the Potomac River Estuary.
Purpose:
The purpose of the data layer is to provide all of the unique shot point navigation associated with the seismic-reflection profiles collected on USGS cruise 06018.. This information can help correlate the seismic-reflection profiles with other features and data in the GIS. This clean, unique shot point navigation is also used as the navigation when loading the seismic data into a digital interpretation software package.

Logical_Consistency_Report:
These points were visually checked to make sure they were viable fixes. All days were handled the same way, even though the acquisition software changed during the cruise.
Completeness_Report:
This shapefile represents all the unique shot point navigation collected during USGS cruise 06018.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
A differential global positioning system (DGPS) was used for the seismic-reflection data. This system was an Ashtech DGPS2 with the navigation being recorded by HYPACK navigation software. The offset from the seismic transducer to the DGPS antenna was 2 meters. This offset was not entered into the software.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Although bathymetry was not recorded directly with this system, bathymetry can be derived by tracing the seafloor reflector in the seismic-reflection profiles. The seismic transducers were mounted on an over the side mount on the port side of the ship. The transducer draft was 0.7 m below the water surface. The draft offset was not included in the data acquisition.

Source_Contribution:
The seismic acquisition system used on this cruise was a Knudsen Engineering Limited (KEL) 1600 USB system. The system has up to 1.2 kW power and is tuned to work with two Massa 3.5 kHz transducers. The transducers were mounted on an over-the-side mount on the port side of the ship. The transducer draft was 0.7 m below the water surface. This draft offset was not included in the data acquisition. The seismic data acquisition software was SounderSuite-USB Beta. This system failed to acquire navigation data from the DGPS NEMA string on the first two days (Julian day 149 and 150). The software was also not able to record data in SEG-Y standard format. KEL KEB format files were logged to disk. In addition, KEA ASCII files with shot (ping) numbers and times were saved to disk. Shot point navigation was also absent in the KEA files on Julian days 149 and 150. On Julian day 151 a patched version of SounderSuite was received and installed. This version recorded navigation in the KEB and KEA files. SEG-Y recording was still not an option. A time server was used to synchronize the DGPS time on the KEL and HYPACK navigation systems. This was important as KEL SounderSuite records system time. Data were acquired at a 20 micro-second sample interval, 2048 samples for a 40 ms record length. Fire-rate was 0.20 seconds (or 5 shots per second). The KEL SounderSuite software was set up to automatically switch files at shot 20,000. Line 5 switched from file 0005_2006_249_2014_002.keb after shot 13509 to a new file (0005_2006_249_2014_003.keb) while changing display parameters, due to a bug in the acquisition software.
Process_Step:
Process_Description:
The KEL SounderSuite acquisition system records two files with every seismic profile. The file containing the seismic data has the extension KEB. The files with the KEA extension are the ASCII navigation files. The prefix filenames are of the format LLLL_YYYY_JJJ_HHMM_FFF where LLLL refers to the line number, YYYY refers to the year of acquisition, JJJ refers to the Julian day of acquisition, HHMM refers to the hour and minute of the start of acquisition, and FFF refers to the file number associated with the line. Because the KEL software was set to increment the file number at 20,000 shots, it's possible to have multiple files for a single line of acquisition. An example filename is: 0024_2006_251_1733_002. This is line 24, collected in the year 2006 on Julian day 251 with a start time of 17:33. This is part 2 of line 24. KEB seismic files were converted to standard SEG-Y files using KEL's PostSurvey version 1.56 software. During the first two days of data acquisition (Julian day 249 and 250 - Sept. 6 and Sept 7), the seismic acquisition software failed to record the navigation data from the DGPS NEMA string in the KEB and KEA files. However, after receiving a patched version of the SounderSuite software, navigation was recorded in the KEB and KEA seismic files. The KEB file is the KEL format seismic profile, while the KEA files is the KEL ASCII navigation file. On the first two days, the KEA files recorded shot number and times. A time server was used to synchronize the GPS time on the KEL with the HYPACK navigation system as the KEL SounderSuite records system time. The prefix filenames are of the format LLLL_YYYY_JJJ_HHMM_FFF where LLLL refers to the line number, YYYY refers to the year of acquisition, JJJ refers to the Julian day of acquisition, HHMM refers to the hour and minute of the start of acquisition, and FFF refers to the file number associated with the line. Because the KEL software was set to increment the file number at 20,000 shots, it's possible to have multiple files for a single line of acquisition. An example filename is: 0024_2006_251_1733_002. This is line 24, collected in the year 2006 on Julian day 251 with a start time of 17:33. This is part 2 of line 24.

The shot number and time of day were extracted from the SU headers and saved in an ASCII file.
Process_Date: 2006
Process_Step:
Process_Description:
An AWK script was used to parse the one-second HYPACK navigation files to output time of day and UTM, zone 18 eastings and northings. A navigation file with Julian day, time, and UTM zone 18 coordinates was concatenated for each Julian day (coordinates were rounded to integers).
Process_Date: 2006
Process_Step:
Process_Description:
The ASCII navigation data were merged with the shot point and time files based on the common field of Julian day, hours, minutes, and seconds using the Unix command "join" on a Mac OS X computer. The output is a shot point navigation file with fixes every five shots (1 second) for the KEL Chirp data. Julian day 151 was processed the same even though position was available in the trace headers. A command line example of the join command is:
 join 0001_2006_249_1340_001.txt jd249_utm.txt >  0001_2006_249_1340_001.spt
Process_Date: 2006
Process_Step:
Process_Description:
An AWK script was run within a shell script on a Mac OS X to take the complete seismic navigation and reformat it with Cruise ID, linename, shot, easting and northing. The shell script formatjday:
#! /bin/csh
 awk '{FS=" "} {OFS=" "} {printf "%5s %25s %5.0f %6s %7s\n", \
cruise,line,$2,$3,$4,$1} ' cruise=06018 line=$1 $1.spt >> $2.spnav

The combined file was renamed with the extension TXT and a header line was added to the file. This file was then added to ArcMap 9.0 as an event theme using Tools - Add XY data and defining the projection as UTM, zone 18, NAD83. The x field is the easting field, and the y field is the northing field. The event theme was then exported as a shapefile by right-mouse clicking on the theme - Data - Export.

The first recorded line for line 5 needed to be split into two parts. The file naming in terms of files as the ship travels was originally - part 2, part 1, part 4. In order to better use this shapefile for future work which will sort on filename, shots were renamed from "part 1" to fit in with the direction of boat travel so that now there is part 2, part 3, part 4. (the original part 1 is now part 3).

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 cross-reference link to the SEG Y publication was fixed. The source information was incomplete and had to be modified to meet the standard. The distribution format name was modified in an attempt to be more consistent with other metadata files of the same data format. 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.
