DELILAH Sediments
[an error occurred while processing this directive]

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.
