R/V Parke Snavely (source vessel) navigation and survey geometry from USGS field activity 2021-619-FA collected in April of 2021 offshore Santa Cruz, CA
Navigation data were recorded for the R/V Parke Snavely (RVPS; source vessel) during USGS field activity 2021-619-FA in April of 2021 off the coast of Santa Cruz, California. Data were collected as the RVPS towed a marine sparker sound source along seven depth site transects in water depths ranging between 25 and 600 meters. The R/V San Lorenzo (RVSL; receive vessel) maintained a nearly stationary position at the midpoint along the seven depth site transects and recorded sound with a calibrated hydrophone. ... |

Sound velocity vs. depth plots and CTD cast data collected in April 2021 offshore Santa Cruz, California during USGS field activity 2021-619-FA
Sound velocity and CTD (conductivity, temperature, depth) cast data were collected at 9 sites offshore Santa Cruz, CA during USGS field activity 2021-619-FA in April of 2021. Aboard the R/V Parke Snavely (RVPS), a SonTek CastAway-CTD was used to collect these data at in the upper 67 meters of the water column. these data is provided in csv format, a shapefile of cast locations, as well as PNG plots of the speed of sound as a function of depth for each cast location. |
