Abstract

SEISMIC_LINES contains line data describing the results of 1-channel and 12-channel seismic refraction studies mapped at a scale of 1:24,000, from the Maine Geological Survey. The results include the depth to the water and depth to the bedrock.

Purpose

Basic data used in developing significant gravel aquifer maps.

Data Set Credit

Credit should be given to the data source and/or originator when data is transferred or printed. Source should be cited as: Maine Department of Conservation, Maine Geological Survey, 22 State House Station, Augusta, ME 04333-0022.

Native Data Set Environment

Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 3; Esri ArcGIS 10.1.0.3035

Attribute Accuracy Report

Attribution of the data set was checked for data entry errors through a series of reviews that checked for inconsistencies with interpretation results. The coverage has been checked for errors and attribution is complete.

Horizontal Positional Accuracy Report

The data were compiled on a 1:24,000 scale base with a horizontal accuracy +/- 40 feet or 12 meters. Seismic line locations were constructed from a point (determined either by plotting position on a USGS topographic map based on odometer measurements and landmarks, or, for more recent data, with GPS), an azimuth, and a seismic line length.

Process Description

Seismic refraction is a surface geophysical technique that uses the travel time of sound waves through various materials to determine the thickness of the layers below the ground surface. The technique can distinguish between unsaturated sand and gravel, saturated sand and gravel, and bedrock, so that in areas of sand and gravel it is possible to determine the depth to the water table and the depth to bedrock, and by difference the saturated thickness of sand and gravel. The information is used in the delineation of areas of significant sand and gravel aquifers.
