Data acquisition logs in PDF format maintained on U.S. Geological Survey Field Activities 2008-007-FA and 2008-037-FA in Great South Bay, Long Island, New York in May and September, 2008
Abstract:
An investigation of submarine aquifers adjacent to the Fire Island National Seashore and Long Island, New York, was conducted to assess the importance of submarine groundwater discharge (SGD) as a potential nonpoint source of nitrogen delivery to Great South Bay. More than 200 kilometers (km) of continuous resistivity profiling (CRP) data were collected to image the fresh-saline groundwater interface in sediments beneath the bay. In addition, groundwater sampling was performed at sites (1) along the northern shore of Great South Bay, particularly in Patchogue Bay, that were representative of the developed Long Island shoreline, and (2) at sites on and adjacent to Fire Island, a 50-km-long barrier island on the southern side of Great South Bay. Other field activities included sediment coring, stationary electrical resistivity profiling, and surveys of in-situ pore water conductivity. The onshore and offshore shallow hydrostratigraphy of the Great South Bay shorelines, particularly the presence and nature of submarine confining units, appears to exert primary control on the dimensions and chemistry of the submarine groundwater flow and discharge zones. Sediment coring has shown that the confining units commonly consist of drowned and buried peat layers likely deposited in salt marshes. Based on CRP data, low-salinity groundwater extends from 10 to 100 meters (m) offshore along much of the northern and southern shores of Great South Bay, especially off the mouths of tidal creeks, and beneath shallow flats to the north of Fire Island adjacent to modern salt marshes. Human modifications of much of the shoreline and nearshore areas along the northern shore of the bay, including filling of salt marshes, construction of bulkheads and piers, and dredging of navigation channels, has substantially altered the natural hydrogeology of the bay's shorelines by truncating confining units and increasing recharge near the shore in filled areas. Better understanding of the nature of SGD along developed and undeveloped shorelines of embayments such as this could lead to improved models and mitigation strategies for nutrient overenrichment of estuaries.

Why was the data set created?

The purpose of this PDF is to provide a copy of the data acquisition logs kept in the field. These types of logs can be invaluable in sorting out issues and questions related to the data collected in Great South Bay during Field Activity Numbers 2008-007-FA and 2008-037-FA.

How was the data set created?

    The handwritten log books maintained by Chuck Worley and John Bratton were scanned and converted to PDF documents by the scanner. The individual PDF files were combined into a single PDF using Adobe Acrobat Professional version 8.2.2. Person who carried out this activity:

    Edits to the metadata were made to fix any errors that MP v 2.9.36 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.). Attempted to modify http to https where appropriate. Updated the link to the field activity. Replaced the offline data access with online data access in the distribution section. 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. Person who carried out this activity:

    This PDF document contains all the information recorded in Chuck Worley's and John Bratton's data acquisition log books related to data collection in Great South Bay. This work covered two cruises - Field Activity Number 2008-007-FA and 2008-037-FA. Chuck Worley only has notes from Great South Bay during the first field activity. The notes from John Bratton actually cover other areas on the north shore of Long Island in addition to the work in Great South Bay. The reason these pages were included was because of instrument problems that required a new system shipped to the field. Because the new system was used in Great South Bay in May, those notes were left in. Also, no page was generated for the boat layout for the September portion of the cruise. However, the boat (R/V Terrapin) and its configuration were identical to work along the north shore of Long Island - so that boat configuration is included as the last page in the PDF.
  5. How consistent are the relationships among the observations, including topology?
