Therefore, it can be read by Res2dinv software. The data was processed using SiberTool Software to export. The data was collected by injecting an electric current inside the Earth's surface using a Wenner configuration with a path length of 148.8 meters.

In order to capture the current topography and to provide a basis for subsequent visualisation, relief data were collected by total station mapping (Leica TPS 700) and GPS measurements during several field campaigns and converted into a high resolution digital elevation model. Measurement value willMetadata also available as - Export to various formats (txt, Res2dinv,) and visualization of the exported files Electre Pro The ELECTRE Pro software is a program allowing to create some 2D-3D-surface/boreholes sequences of measurement for IRIS Instruments SYSCAL Pro-Switch resistivity-meters.Processing of resultant data was carried out with RES2DINV software. We get different potential used to calculating apparent resistivity, PFE, and MF.Then, we model each parameter by Surfer 9.0 and inverse it by Res 2Dinv. All tools with its specification which has been used have shown in Appendix A. Geological Survey Field Activity 2010-006-FAsoftware Microsoft excel 2007, software Surfer 9.0, and software Res2Dinv. The results show that leachate seepage at TPAS Ampang Kualo on track one was around a leachate pond stretching from South to North.RES2DINV format continuous resistivity profiling data collected in the Indian River Bay, Delaware, on April 15, 2010, on U.S.

How does the data set represent geographic features? What is the general form of this data set? Does the data set describe conditions during a particular time period?

How reliable are the data what problems remain in the data set? What similar or related data should the user be aware of? How were the data generated, processed, and modified? From what previous works were the data drawn? To whom should users address questions about the data? Who are the originators of the data set?

Where are the gaps in the data? What is missing? How accurate are the heights or depths? How accurate are the geographic locations?

The total length of continuous resistivity profiling (CRP) survey lines was 145 kilometers (km), with 36 km of chirp seismic lines surveyed around the perimeter of the bay. This included surveying at higher spatial resolution in the vicinity of a study site at Holts Landing, where intensive onshore and offshore studies were subsequently completed. What legal disclaimers am I supposed to read?A geophysical survey to delineate the fresh-saline groundwater interface and associated sub-bottom sedimentary structures beneath Indian River Bay, Delaware, was carried out in April 2010. What's the catalog number I need to order this data set? Are there legal restrictions on access or use of the data? How can someone get a copy of the data set?

Where present, these units allow plumes of low-salinity groundwater that was recharged onshore to move beyond the shoreline, creating a complex fresh-saline groundwater interface in the subsurface. Many paleochannels also had high-resistivity anomalies corresponding to low-salinity groundwater plumes associated with them, likely due to the presence of fine-grained estuarine mud and peats in the channel fills that act as submarine confining units. An especially wide and deep paleochannel system was imaged in the southeastern part of the bay near White Creek. Results of the surveying and data inversion showed the presence of many buried paleochannels beneath Indian River Bay that generally extended perpendicular from the shoreline in areas of modern tributaries, tidal creeks, and marshes.

These models are required to help predict how nutrient-rich groundwater, recharged in agricultural watersheds such as this one, makes its way into coastal bays and impacts surface water quality and estuarine ecosystems.

The maximum depth below the water surface the streamer can reach is approximately 1/4 the streamer length. 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 source electrodes are graphite, while the receiver electrodes are stainless steel. How were the data generated, processed, and modified? Date: 2010 (process 1 of 5)The continuous resistivity profile (CRP) system used on this cruise was an AGI SuperSting marine system described at the website: The particular system used for this acquisition was a 50-m streamer with an 11 electrode array with electrodes spaced 5 meters apart. RES2DINV is another format for resistivity data that is used by numerous universities and researchers. These data were collected by the AGI SuperSting system and recorded in the AGI format.

The STG file contains the resistivity data, while the GPS file contains the navigation information. The two files necessary for processing are the *.stg and the *.gps file. Each line of data acquisition records several files.

The approximately 2 m lateral offset is not accounted for. This layback offset is accounted for by the acquisition system. On April 15 the antenna and transducer were move 1.6 m after making changing the layback offset to 16 m. The layback offset between the navigation antenna and the first electrode was 17.6 meters on April 13 and 14. The streamer tow point was on the port side aft. The antenna and fathometer transducer were mounted on the starboard side of the boat.

Person who carried out this sources used in this process:Edits to the metadata were made to fix any errors that MP v 2.9.36 flagged. A more complete description of all the processing involved prior to this point can be found in the metadata for the raw resistivity data and the processed resistivity data available at. These line names are what the * refers to in the source used and source produced citations. The lines processed on this day are L20F2, L21F1, L22F1, L23F1, L24F1, L25F1, L26F1, L26F2, L27F1, L28F1, L29F1, L30F1, L31F1, L32F1, L33F1, L35F1, L36F1, L37F2, L38F1, L39F1, L40F1, L41F1, L42F1, L43F1, L44F1, L45F1, L46F2, L47F1, L48F1, L49F1, and L50F1. The conversion was accomplished by a Visual Basic 6 program written at the USGS office in Woods Hole (AGI2res2d.exe - no version number). 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.The linearized STG and DEP files generated by AGI's Marine Log Manager software AGI SSAdmin MLM v 1.3.4 were converted to a format suitable for the RES2DINV processing software.

The metadata date (but not the metadata creator) was edited to reflect the date of these changes. Moved the minimal source information provided to make it the first process step. Attempted to modify http to https where appropriate. Other minor edits were probably performed (title, publisher, publication place, etc.). In some cases, this meant adding text 'Information unavailable' or 'Information unavailable from original metadata' for those required fields that were left blank.

Compare the metadata dates to determine which metadata file is most recent.Loke, M.H., 2001, Electrical imaging surveys for environmental and engineering studies - a practical guide to 2D and 3D surveys: University Sains Malaysia, Penang, Malaysia.
