High-resolution chirp seismic-reflection data collected offshore Oceanside, southern California during field activity 2017-686-FA from 2017-10-23 to 2017-10-31

Summary

This section of the data release contains approximately 369 line-kilometers of processed, high-resolution chirp seismic-reflection profiles that were collected aboard the R/V Snavely in 2017 on U.S. Geological Survey cruise 2017-686-FA offshore Oceanside, southern California. The along-shore and across-shore chirp profiles are 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. The chirp profiles were acquired using an Edgetech 512 Chirp sub-bottom profiling system.

Purpose

The U.S. Geological Survey (USGS) collected high-resolution chirp seismic-reflection profiles in 2017 offshore Oceanside, southern California. The goal of the chirp survey was to provide high-resolution imaging to characterize the surface and subsurface properties of the study area, including unconsolidated sediment thickness and subsurface sediment horizons. This cruise was funded through partnerships with the Bureau of Ocean Energy Management (BOEM) and the State of California Ocean Protection Council (OPC).
