Dataset description: CHIRP seismic-reflection and navigation data

CHIRP seismic-reflection data and associated navigation files were collected offshore central California in the vicinity of Morro Bay. These data were collected aboard the M/V Bold Horizon in October 2019 for use in regional hazard assessments relating to the Hosgri Fault.

2019-651-FA	512 chirp is a seismic reflection instrument that uses sound to examine the layering of sedimentary strata on and below the sea floor. The Chirp being used in this project is a modified version of the Subscan 512 made by Edgetech. The noise it makes actually sounds like a bird's chirp; the frequencies of the sound it produces are between 500 Hz and 12 kHz. The Chirp has two advantages that allow it to get excellent penetration (meaning it can see deep, like >50 m or >64 ft, into the seabed) and high resolution (meaning it can make out fine layering, layers
