| Abstract: | The KISAP (Korea Institute of Geoscience and Mineral Resources Seafloor Acoustic Probe) was developed to obtain in situ compressional wave velocity and attenuation profiles for seafloor sediments. The instrument comprises recording channel receivers, and an acoustic source, and can be attached to a corer or a probe. Here, we report experiments comparing KISAP in situ velocity to laboratory velocity of colocated piston cores. KISAP data matched laboratory data (corrected for temperature and pressure) reasonably. KISAP can be used to collect in situ acoustic data and can be effectively used to calibrate previous laboratory data to in situ data. |
