Figure 3.4. Seismic-reflection profile offshore of the Murrells Inlet area. TOP: Original data showing vertical slice through the upper 20 m (66 ft) of the seafloor. BOTTOM: Interpreted profile showing the primary framework components underlying the inner shelf. Location indicated in Figure 3.1D. Two-way traveltime is in milliseconds and depth is in meters. A constant seismic velocity of 1.5 km/s was used to convert from two-way traveltime to depth (modified from Baldwin and others, 2006). ~, about; <, less than. [Click here for high-resolution image.]
