This is a grain size distribution curve chart for a composite core sample collected from the Sea Bright Borrow Area. The chart presents particle size analysis data for boring number 88-74 at elevation 0-28 feet. The graph displays the cumulative percent coarse material by weight on the left vertical axis and percent finer by weight on the right vertical axis, plotted against grain size in phi units on the horizontal axis. The material composition ranges from gravel (coarse and fine) on the left side through sand (coarse, medium, and fine) in the central portion to silt on the right side. The curve indicates that approximately 16 percent of the sample is coarser than the median grain size, with the distribution showing a predominantly sandy composition with minor gravel and silt components. The chart was dated November 1975 and is referenced as NAD 1.
