Each of four size classes of foreshore sand from Sandy Hook, New Jersey, was color coded with daylight and ultraviolet fluorescent coating material. These tracer particles were introduced at mid-swash line on the foreshore surface at Kingmill Beach, Sandy Hook, two hours prior to high tide. During the test Atlantic Ocean waves approaching at an angle of approximately 5 degrees to the shoreline caused 5.3-second breakers of 0.73 meter maximum height. In a time-integration procedure samples were obtained by channel sampling on the foreshore along a sampling line, transverse to the foreshore, that was established 30.5 meters downdrift from the point of introduction of tracer particles. Sub-samples of the 18 samples taken during the 49.7 minutes after marked particle introduction were examined for tracer particle content. Recovery data indicate particles in the smallest size class (0.701 >d>0.589 mm) began arriving at sampling line 18.2+ or -0.7 minutes after introduction: equivalent to 2.8 cm/sec average maximum transport velocity. Particles in the next largest size class began arriving 25.8+ or -1.7 minutes after introduction: equivalent to 2.0 cm/sec average maximum transport velocity. However, a maximum number of marked particles in both size classes was found in a sample taken 42.3 minutes after introduction. Only one particle in each of the two larger size classes (1.397 > d > 1.168 and 1.168 > d >0.991 mm) was recovered. Particle-recovery distribution is assumed to be influenced by sample size and total weight of particles in each size class containing marked particles. Converted particle-recovery distribution is based on weight ratio of marked particles to total particles in each appropriate size class. These data show a 3.2-minute delay in peak arrival of particles in size class 0.840>d>0.701 mm relative to peak recovery of particles in size class 0.701 > d > 0.589 mm. Therefore, for these two size classes both first arrival and converted peak arrival data indicate an inverse size-velocity relationship prevails in beach drift transport.
