Abstract: Abstract: Suspended-sediment samples were collected in and near the surf zone from Jennette's Pier, Nags Head, North Carolina, and the City Pier, Ventnor, New Jersey, using a tractor-mounted pump sample. Maximum suspended-sediment concentrations at Ventnor ranged up to 2.6 parts per thousand by weight, and at Nags Head up to about 4.0 parts per thousand. As in previous studies, the log of concentration decreased linearly with elevation above bottom for samples away from the bottom, but near-bottom concentration was higher than the extrapolated log trend. Concentration increased as local height-to depth ratio increased, to a maximum near the theoretically predicted maximum height-to-depth ratio. Plunging breakers appear to suspend more sediment than spilling breakers. ~1edian sand size at Ventnor ranged from 0.12 to 0.15 millimeter and at Nags Head averaged about 0. 21 millimeter. The median size of suspended-sediment samples was lower than bottom samples. Potential applications, including an example on longshore transport, arc discussed. The results of this report are based on a total of.850 samples, each pumped for 2.5 to 3 minutes and more than half collected in the 0.2 to 0.5 foot range above the bottom.
