Abstract:
This is the sub-bottom profiler data collected during cruise MSM109 using the hull-mounted parametric sub-bottom profiler Atlas Parasound P70. This data collection includes the transits from Tromsø to the Svalbard region, the surveys, and the transit back to Reykjavík. The system utilises two high-intensity waves with frequencies of 18-20 kHz (primary high frequency; PHF) and 22-24 kHz to create a secondary high (about 40-42 kHz) and secondary low frequency (SLF) of about 4 kHz. The PHF is used to record the water column, while the SLP records the sub-bottom data. The system opening angle is of 4 by 5 degrees. A Surface Sound Velocity sensor was used in real time to correct the data transmission, and for the water column a static values of 1500 m/s was used. Data was logged using the software Atlas Parastore and stored in raw .ASD files. Additional files were created in .PS3 and/or .SEGY formats, but their data is dependent on the settings and parameters used in the system.
