The embayments are bounded by steep moraines and are underlain by thick fine-grained sediments deposited in proglacial lakes during the last ice age. Beach sand and gravel overlie the glacial deposits along the coast. The continuous resistivity profiling (CRP) surveys that were conducted indicate the existence of low-salinity groundwater in shore-parallel bands, typically 25 to 50 meters wide, along the shorelines of both bays. Piezometer sampling and seepage meter deployments in intertidal and subtidal areas of the two bays confirmed the presence and discharge of brackish and low-salinity groundwater. The large tidal ranges (up to 3 meters), and the steep onshore topography and hydraulic gradients are important variables controlling coastal groundwater discharge in these areas. For more information on the survey involved in this project, see http://quashnet.er.usgs.gov/data/2008/08007/. Purpose: The purpose of this polyline shapefile is to indicate the ship's position during the continuous resistivity profile survey in Manhasset Bay on northern Long Island, New York from May 15 to May 17, 2008. These lines can also be used to hyperlink to JPEG images of the corresponding resistivity profile enabling the resistivity data to be placed in spatial context with other GIS data.

The "line" attribute reflects the linename assigned in the field. In general, the format is LXFX, which would refer to line number, file number (in the case that more than one file was collected on a single line). There are exceptions to this naming convention, and are usually a result of typos when entering the linename. Completeness_Report: All the points in the input shapefile were used to generate these polylines. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The navigation system used was a Lowrance 480M with an LGC-2000 Global Positioning System (GPS) antenna. The antenna was located at the anchor point for the resistivity streamer, which is also directly above the fathometer transducer mount point. The GPS system is published to be accurate to within 10 meters. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: All bathymetry values were collected by the 200 kHz Lowrance fathometer. The fathometer was mounted starboard side aft, directly below the GPS antenna and the resistivity streamer tow point. The transducer was approximately 0.30 meters below the sea surface, and this draft was not corrected for. The Lowrance manufacturer indicates the speed of sound used by the system to convert to depths is 4800 feet/second (1463 meters/second). All values are assumed to be accurate to within 1 meter. Lineage: Source_Information: Source_Contribution: The continuous resistivity profile (CRP) system used on this cruise was an AGI SuperSting marine system described at the website: www.agiusa.com/marinesystem.shtml. Two different streamers were used for data collection - not simultaneously. One streamer was a 50-m streamer with an 11 electrode array with electrodes spaced 5 meters apart. The other streamer was a 15-m streamer with an 11 electrode array with electrodes spaced 1.5 meters apart. In both cases, the source electrodes are graphite, while the receiver electrodes are stainless steel. A dipole-dipole configuration was used for the data collection in which two fixed current electrodes are assigned with the measurement of voltage potential between electrode pairs in the remaining electrodes. The maximum depth below the water surface the streamer can reach is approximately ¼ the streamer length. So for the 50-m streamer, maximum depth is about 12.5 meters, while the 15 meter streamer can reach about 3.75 meters. Each line of data acquisition records several files. The two files necessary for processing are the *.stg and the *.gps file. The STG file contains the resistivity data, while the GPS file contains the navigation information. The navigation system used in concert with the CRP system is a Lowrance LMS-480M with an LGC-2000 GPS antenna and a 200 kHz fathometer transducer. The transducer also contains a temperature sensor. Lowrance indicates the speed of sound used by the system is 4800 feet/second. Both the temperature and depth information are recorded in the logged GPS file. The CRP system images the subsurface electrical properties of an estuarine, riverine or lacustrine environment. Resistivity differences can be attributed to subsurface geology (conductive vs less conductive layers) and hydrogeologic conditions with fresh water exhibiting high resistivity and saline conditions showing low resistivity. Process_Step: Process_Description: In ArcMap 9.2 an ArcMap extension written in Woods Hole (VACExtras, v2.1) was used to convert the individual navigation points to lines for each day of surveying in Manhasset Bay. The "Points to Line v2" tool within the extension was used. The user selects an attribute to be the unique identifier used to group the points into a line; in this case, the attribute "linename" was used. The script assumes the order of the points in the point shapefile is the order they need to be added to the line, and the projection of the output shapefile is the same as the input point shapefile. The user can also select additional attributes to be carried over to the output polyline shapefile. The value written out is the first occurrence of the attribute on the unique "line". The additional attributes carried over were gpstime, depth, tempc, location, streamer, jday, and col_date. This process step, along with all subsequent process steps, was performed by the same person: VeeAnn A. Cross.

Overview_Description: Entity_and_Attribute_Overview: In order to effectively utilize the "hotlink" or "hlink2" attribute in ArcGIS, the user must follow a couple of steps. First, the user must open the Layer Properties of the shapefile within ArcMap - 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" or "hlink2". The hyperlink is set to a document. Additionally, a hyperlink base must be supplied in the ArcMap document (mxd) 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 preceding "data" in the full path to the image. If the data are being read from a CD-ROM, this would be the drive letter such as F:\.
