Description:

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.

Purpose:

This shapefile is used to provide the drilling locations within the Cape Cod National Seashore in 2005 where piezometers were placed to sample submarine groundwater. The related comma-delimited text file which contains the measurement data is piez_gwdata.csv. The common related attribute between the two files is "site".

Data_Quality_Information:

Logical_Consistency_Report:

No additional checks for topological consistency other than visual inspection were performed on the data.

Completeness_Report:

No piezometer data were collected on 8/23/2005. All sites where piezometer groundwater data were collected are included. This shapefile essentially contains the sample locations. At each site, multiple groundwater samples were acquired and analyzed. This shapefile has a one-to-many relationship with the stand-alone comma delimited text file piez_gwdata.csv which contains the actual groundwater quality measurements.

Overview_Description:

Entity_and_Attribute_Overview:

A hydraulic vibratory drilling rig mounted on an all-terrain vehicle and secured to a barge was used to advance piezometers for submarine ground-wtaer sampling. These piezometers consisted of 2.5 cm diameter steel pipe in 3.4 m lengths that were joined by hydraulically crimped couplings. Water samples were taken general every 305 cm with water quality measurements of temperature, conductivity, dissolved oxygen, pH, and oxidation-reduction potential made using a YSI 650 Multi-Parameter data sonde. In addition, filtered samples were collected for nutrient measurements. These measurements are stored in the related comma-delimited text file piez_gwdata.csv.
