Sediment grain size data from samples collected offshore Oceanside, southern California during field activity 2017-686-FA from 2017-10-23 to 2017-10-31

Metadata Updated: July 6, 2024

This section of the data release contains grain-size analysis of twenty-six seafloor surface grab samples that were collected aboard the R/V Snavely in 2017 on U.S. Geological Survey cruise 2017-686-FA offshore Oceanside, southern California. The samples were collected at strategic locations along the same transects as seismic-reflection lines oriented to assess sand and gravel resources in Federal and State waters for potential use in future beach nourishment projects along stretches of the coast where critical erosion hotspots have been identified. Samples were collected at 23 locations using a Van Veen sediment sampler along 4 shore-perpendicular transects spaced 5 to 9 km apart, aligned with previously collected seismic profile lines, at depths ranging from about 20 to 80 m. One sample on the outer shelf (BSS-06) was collected to evaluate an area of suspected sand occurrence. Two duplicate samples were collected at one location (BSS-08) in order to evaluate local sample variability.
