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: To provide the calibrate route polyline for the seismic-reflection profiles collected on this cruise. These lines are calibrated based on shot number so that using the route identifier tool allows the user to find the location of a specific shot on any seismic trackline. This helps correlate the seismic-reflection profiles with other GIS data available in the area.

Browse_Graphic_File_Type: GIF Native_Data_Set_Environment: Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; ESRI ArcCatalog 9.2.6.1500 Data_Quality_Information: Logical_Consistency_Report: No additional checks for topological consistency were performed on the data. Completeness_Report: All of the shot point navigation from this cruise was incorporated in this shapefile. 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, 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.

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: An ArcView 3.3 avenue script written in Woods Hole (point2line.ave) was used to connect the individual shot points using the attribute "linename" as the unique line identifier. That attribute is also brought over to the resulting polyline shapefile. This process step, as well as all subsequent process steps, were performed by the same person - VeeAnn A. Cross.

Source_Used_Citation_Abbreviation: track_route_Calib_geog.shp Process_Date: 2009 Source_Produced_Citation_Abbreviation: track_route_Calib_geog.shp Process_Step: Process_Description: Edits to the metadata were made to fix any errors that MP v 2.9.34 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 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.

Overview_Description: Entity_and_Attribute_Overview: In order to effectively utilize the "hotlink" attribute in ArcGIS, the user must follow a couple of steps. First of all, within ArcMap, the user must open the Layer Properties of the shapefile - select the Display tab - and click on the check box next to "Support Hyperlinks using field:" and the field selected from the dropdown menu needs to be "hotlink". The hyperlink is set to a document. Additionally, a hyperlink base must be supplied to complete the full path to the images. This is accomplished from File - Document Properties. On the Summary tab there is a section for "Hyperlink base". The text supplied here needs to be the disk information preceeding "data" in the full path to the image. If the data are being read from a DVD, this would be the drive letter such as F:\.
