Figure 1. Map of Long Island, New York, indicating glacial features on the island. The base image was acquired from Stony Brook University (http://www.geo.sunysb.edu/reports/dem_2/), accessed June 2011. |

Figure 2. Map showing the locations of possible glacial tunnel valleys along the north shore of Long Island, New York. The base image was acquired from Stony Brook University (http://www.geo.sunysb.edu/reports/dem_2/), accessed June 2011. |

Figure 3. Location map showing the continuous resistivity tracklines in Manhasset Bay and Northport Harbor on the north shore of Long Island, New York. |

Figure 4. Continuous resistivity profiling (CRP) streamer deployed behind the survey boat (photo is from a different survey). Foam flotation is attached to the cable between each electrode. Photo by John Bratton, NOAA. |

Figure 5. Continuous resistivity profiling (CRP) data acquisition system in the survey boat (photo is from a different survey). The yellow box to the left is the AGI SuperSting R8 resistivity meter, the black box in the middle manages the battery power to the system, and the yellow box to the right contains the Lowrance GPS-enabled fathometer.

Figure 6. Perspective view of a horizontal slice at 5 meters below zero elevation through a three-dimensional (3D) solid model created from the CRP data in Dynamic Graphics' EarthVision software in Northport Harbor. The individual CRP measured values used to construct the model are not sliced and can be seen in the 3D model. Although a scale bar is not appropriate for a perspective view, the ticks along the x-axis are 250 meters apart. The white box on the plan view of the topography marks the approximate bounds of the block. The color scale bar has the units of ohm-meters. The topography image is cropped from the base image and was acquired from Stony Brook University (http://www.geo.sunysb.edu/reports/dem_2/), accessed June 2011. |

The individual CRP measured values used to construct the model are not sliced and can be seen in the 3D model. Although a scale bar is not appropriate for a perspective view, the ticks along the x-axis are 500 meters apart.The white box on the plan view of the topography marks the approximate bounds of the block. The color scale bar has the units of ohm-meters.
