To date, state-of-the-art seismic material parameter estimates from multi-component sea-bed seismic data are based on the assumption that the sea-bed consists of a fully elastic half-space. In reality, however, the shallow sea-bed generally consists of soft, unconsolidated sediments that are characterized by strong to very strong seismic attenuation. To explore the potential implications, we apply a state-of-the-art elastic decomposition algorithm to synthetic data for a range of canonical sea-bed models consisting of a viscoelastic half-space of varying attenuation. We find that in the presence of strong seismic attenuation, as quantified by Q-values of 10 or less, significant errors arise in the conventional elastic estimation of seismic properties. Tests on synthetic data indicate that these errors can be largely avoided by accounting for the inherent attenuation of the seafloor when estimating the seismic parameters. This can be achieved by replacing the real-valued expressions for the elastic moduli in the governing equations in the parameter estimation by their complex-valued viscoelastic equivalents. The practical application of our parameter procedure yields realistic estimates of the elastic seismic material properties of the shallow sea-bed, while the corresponding Q-estimates seem to be biased towards too low values, particularly for S-waves. Given that the estimation of inelastic material parameters is notoriously difficult, particularly in the immediate vicinity of the sea-bed, this is expected to be of interest and importance for civil and ocean engineering purposes.

In accordance with 19B.5 of the Code of Iowa, the 2005 Affirmative Action in Iowa report illustrates the progress made during fiscal year 2005 to balance the State's worforce, the challenges that the State must address and the effort that the Department of Administratie Services must lead in order to remove barriers that limit the hiring, retention and advancement of females, minorities and persons with disabilities in the State's workforce. Highlighted in the report are four departments that initiated proactive and innovative measures to address their workplace equal opportunity, affirmative action and diversity programs. Additionally, the Department of Administrative Services-Human Resources Enterprise outlines its plan to build on its past efforts as well as pursue new initiatives to partner with advocacy groups and reach out to the commuity more directely to enhance employment opportunities for females, minorities and persons with disabilities in State of Iowa employment.
