Estimates of attenuation structure in the Çınarcık Basin of the Marmara Sea, northwest Turkey

Abstract

Abstract The attenuation structure (1/Q) in the sediments of the Cinarcik Basin of the Marmara Sea was estimated from the raw shot data of a multi-channel seismic reflection experiment using a wavelet modeling technique. The estimated attenuation, called the effective-Q is the sum of the inelastic absorption and the apparent attenuation. The estimated effective-Q values along the north–south trending seismic profiles are interpreted together with their time-migrated seismic sections. There are several local minima in the boundary separating the low (
