Nineteen sediment samples were collected along profile line 230 on 15 October 1990. Beach samples were scraped from the top layer of the beach face. Offshore samples were collected with a clamshell grab sampler by a
person atop the Coastal Research Amphibious Buggy (CRAB) deck. The
samples were then washed, dried, split, and sieved for analysis of grain size and
sorting. The sieving was done with a sonic sifter, which sorts the sediments
through small diameter sieves using high-frequency vibrations.
The size distribution of each sample, along with its relative position along the
profile, are shown in the figure below. The overall nature of the cross-shore size
distribution is typical of sediments at the Field Research Facility with a wide
range in sediment size on the beach face and in the inner bar/trough region.
Seaward of the inner bar, the sediment is composed of fine, well-sorted
sediments.
Below is an example of a table and plot describing sediment sample 1.
All other sediment sample plots can also be viewed from this table.
