Dataset description: Chirp sub-bottom data collected in 2019

These metadata describe high-resolution chirp sub-bottom data collected in May 2019 in Whiskeytown Lake, California. Data were collected and processed by the U.S. Geological Survey (USGS), Pacific Coastal and Marine Science Center (PCMSC) with fieldwork activity number 2018-686-FA. The chirp sub-bottom data are provided in SEG-Y format.

Activities and equipment

Activity	Equipment
2018-686-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
