Sallarès, Valentí 16TH SEISMIX International Symposium on Multi-scale Seismic Imaging of the Earth's crust and Upper Mantle, 12-17 October 2014, Castelldefels, Barcelona.-- 1 page Acoustic reflectivity provides insight into the fine structure of the ocean by using the multichannel seismic reflection method. Retrieving physical properties of the ocean from acoustic reflectivity has been one of the main topics of this subject. Until now, the main inversion strategy has been to invert sound speed from reflectivity. Afterwards, a combination of equations of state and amlocal T-S relationship is required to derive subsequently the rest of parameters (temperature, salinity and density). We have developed an alternative approach based on the direct inversion of temperature and salinity from the reflected waveform. We have implemented a time domain, multiscale, acoustic FWI algorithm with a gradient-based optimization scheme that solves for T and S. The sensitivity kernels of those parameters are calculated via the adjoint method, and we use the iterative non-linear conjugate gradients (NL- CG) search method to minimize a misfit function. We present in this work the T and S inversions obtained from acoustic synthetic data propagated through the thermohaline finestructure of the Gulf of Cadiz, North Atlantic Ocean Peer reviewed 2015-05-12T11:37:47Z 2015-05-12T11:37:47Z 2014-10 póster de congreso http://purl.org/coar/resource_type/c_6670 16TH SEISMIX International Symposium on Multi-scale Seismic Imaging of the Earth's crust and Upper Mantle.
