Description:

Abstract:

As part of a larger investigation to understand groundwater-surface water interactions in Greenwich Bay, Rhode Island, a geophysical survey was conducted from a small research boat on 14-15 May 2009. The specific research objective was to gain an improved understanding of the role of direct groundwater discharge in delivery of excess nitrogen to the bay, which may have contributed to the development of low-oxygen conditions in waters of the bay and associated fish kills. Data collected in this survey included digital navigation information, continuous resistivity profiling (CRP) data, and point salinity measurements. The CRP method is a survey and data processing approach that is sensitive to differences in electrical properties of surface water and underlying porewater in sediments that have contrasting salinities. During the survey, Greenwich Bay salinity was approximately 27 ppm, so surface water would be expected to have low electrical resistivity (high conductivity), and any areas of active groundwater discharge from less salty aquifer sources would yield relatively higher resistivity values. This survey is identified as field activity 09021 (also referenced as 2009-021-FA) by the U.S. Geological Survey, Woods Hole, Massachusetts, and additional information is available from: https://cmgds.marine.usgs.gov/fan_info.php?fan=2009-021-FA.

Purpose:

This point shapefile provides geographic locations and sensor data from the YSI 30 that are used to determine water conductivity values. Also included is the Excel spreadsheet used to derive the shapefile.

The YSI 30 is a handheld system. The unit was placed in the water and measurements taken at 10 locations in Greenwich Bay. The measurements are surface water temperature, salinity, and specific conductance measurements. The specific conductance measurements were temperature-compensated.

Process_Step:

Process_Description:

The temperature, salinity, and specific conductance values were measured with the YSI 30 handheld system. The measured values were recorded manually by the chief scientist in his log book, along with the UTM Zone 19, WGS 84 easting and northing values of the measurement location as read from the Lowrance GPS system. The time recorded with the measurement information is local time.

Process_Step:

Process_Description:

To be consistent with previous resistivity work, the temperature and salinity values recorded by the YSI 30 will be used to calculate the water resistivity value. Two additional columns were added to the Excel spreadsheet. One was the conductivity value in Siemens per meter (S/m) that will be calculated, and the other is the conversion of this value to resistivity in ohm-meters (ohm-m). The website used was: http://www2.sese.uwa.edu.au/~hollings/pilot/denscalc.html which is no longer a valid link. On this website, pressure was entered as 0 dbar. Temperature based on the value in the spreadsheet. Salinity based on the value in the spreadsheet. The conductivity value, in S/m, was recorded to the spreadsheet. These values were in close agreement with the specific conductance values measured by the YSI 30. The resistivity value is simply 1/conductivity, so that calculation was done in Excel and recorded in the resistivity column. This process step and all subsequent process steps were performed by the same person - VeeAnn A. Cross.

Process_Description:

A second sheet was added to the spreadsheet in order to reformat the information for import into ArcGIS. This primarily meant using column heading names that would be acceptable to import into ArcGIS. Additionally, average water resistivity value was calculated based on the measured values.

Process_Date: 200905

Process_Step:

Process_Description:

The second sheet of the Excel spreadsheet was exported as a comma-delimited text file. The schema.ini file (which controls how data are interpreted by ArcGIS) was edited so that certain fields (time) would import as text. Date/time fields can be problematic in ArcGIS. I also used the schema.ini to shorten the column heading names. The schema.ini file is as follows:


[GreenwichBaySalinitiesMay2009_vmod.csv]
Format=CSVDelimited
ColNameHeader=True
Col1=location Text Width 50
Col2=time Text Width 10
Col3=utmzone Text Width 10
Col4=easting Long
Col5=northing Long
Col6=temp_c Float
Col7=sal_ppt Float
Col8=cond_mSpcm Float
Col9=cond_Spm Float
Col10=res_ohm_m Float

Using ArcMap 9.2 - Tools - Add XY data with X field as easting, Y field as northing, and defined the coordinate system as UTM, zone 19, WGS 84 - added the csv file as an event theme in ArcMap. This event theme was then exported to a shapefile using the data export option from the right-mouse click of the event theme in the table of contents.

The point shapefile of the YSI 30 measurement locations was projected from a UTM, Zone 19, WGS 84 projection to a geographic coordinate system - WGS 84. This was done in ArcCatalog 9.3.1 - ArcToolbox - Data Management Tools - Projections and Transformations - Feature - Project. Because the datum is the same in both projections, no datum transformation was necessary.
