High-resolution, chirp seismic-reflection data collected offshore Oceanside to San Diego, southern California, during field activity 2018-638-FA from 2018-05-21 to 2018-05-26

공공데이터포털

This part of the data release contains processed, high-resolution, chirp seismic-reflection profiles that were collected aboard the R/V Bold Horizon in 2018 on U.S. Geological Survey cruise 2018-638-FA offshore Oceanside to San Diego, southern California. Approximately 127 line-kilometers of chirp data were collected offshore Oceanside (BH lines) and 125 line-kilometers were collected offshore Silver Strand, San Diego (SS lines). The data were acquired using an Edgetech 512 Chirp sub-bottom profiling system. These data are divided up and presented by navigation line, as reflected in the individual file names.

Reprocessed single channel sparker seismic reflection data offshore central California from USGS field activities S-6-08-SC and S-6-09-SC

공공데이터포털

The U.S. Geological Survey collected high-resolution single channel minisparker data between Point Sal and Piedras Blancas in 2008 and 2009 with support from the Pacific Gas and Electric (PG&E) CRADA and the USGS Coastal and Marine Geology program. Reprocessing of this data in 2018 improved vertical resolution of the stratigraphy and structural deformation of the original data and was funded by an additional CRADA with PG&E.

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

공공데이터포털

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.
