Comparison of high-resolution seismic profiles and the geoacoustic properties of Eckernforde Bay sediments Academic Article

abstract

• High-resolution seismic profiles of Eckernfrde Bay and the adjacent Baltic Sea were collected, and the geoacoustic properties of sediments there were measured. Bulk densities averaged 1.35 g cm-3 and ranged from 1.2 to 1.7 g cm-3. Compressional wave velocities in gas-free sediments averaged 1460 m s-1 and ranged from 1425 to 1555 m s-1. In nongassy sediments, bulk density variations typically controlled changes of acoustic impedance. Impedance changes were usually too small and closely spaced to be resolved seismically, although, at certain sites, significant impedance changes are far apart enough that they correlate one-to-one with seismic reflectors. Where free gas is present, velocity decreases and wave energy is scattered, causing a prominent seismic reflector.
