Title:
JPEG Images of Cores Collected in August 2006 in the Nauset Marsh Area of Cape Cod, Massachusetts
Abstract:
In order to test hypotheses about groundwater flow under and into estuaries and the Atlantic Ocean, geophysical surveys, geophysical probing, submarine groundwater sampling, and sediment coring were conducted by U.S. Geological Survey (USGS) scientists at Cape Cod National Seashore (CCNS) from 2004 through 2006. Coastal resource managers at CCNS and elsewhere are concerned about nutrients that are entering coastal waters via submarine groundwater discharge, which are contributing to eutrophication and harmful algal blooms. The research carried out as part of the study described here was designed, in part, to help refine assumptions required by earlier versions of models about the nature of submarine groundwater flow and discharge at CCNS. This study was conducted in four phases, with a variety of field techniques and equipment employed in each phase. Phase 1 consisted of continuous resistivity profiling (CRP) surveys of the entire study area conducted in 2004. Phase 2 consisted of CRP ground-truthing via resistivity probe measurements and submarine groundwater sampling from hydraulically-drive piezometers using a barge in the Salt Pond/Nauset Marsh area in 2005. Phase 3 consisted of supplemental detailed CRP surveys in the Salt Pond/Nauset Marsh area in 2006. Finally, Phase 4 consisted of sediment coring and porewater extraction in the Salt Pond/Nauset Marsh area later in 2006 to supplement the 2005 sampling.

  2. How were the data generated, processed, and modified?
    Date: 11-Aug-2006 (process 1 of 9)
    Cores were collected with a vibracorer with an 8-cm diameter aluminum pipe advanced through a moonpool in a large Whaler (~20'). The locations of the cores were selected to approximately reoccupy some of the 2005 drilling locations. Person who carried out this activity:

    Date: 11-Aug-2006 (process 2 of 9)
    The recovered cores were split, described and photographed. The photographs cover roughly 60 cm of the core length, therefore multiple photographs were necessary to cover the complete core. One photo is missing from core 6 - the section covering 300 cm - 360 cm. Person who carried out this activity:

    Date: 2006 (process 3 of 9)
    The individual photographs were appended into a single JPEG image using ImageMagick software. A spacer image was used to fill the blank segment from core 6 (300cm - 360cm) in the composite image. Person who carried out this activity:

    Edits to the metadata were made to fix any errors that MP v 2.9.30 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. Needed to add link to data in the distribution section. Other minor edits were probably performed (title, publisher, publication place, etc.). 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:
