Overview of SAX99: environmental considerations

摘要: A 1-km/sup 2/ area located 2 km off the Florida Panhandle (30/spl deg/22.6'N; 86/spl deg/38.7'W) was selected as site to conduct high-frequency acoustic seafloor penetration, sediment propagation, and bottom scattering experiments. Side scan, multibeam, normal incidence chirp surveys well subsequent video surveys, diver observations, vibra coring, indicate a uniform distribution of surficial subbottom characteristics within area. The site, in 18-19 m water, is characterized by 1-2-m-thick fine-to-medium clean sand meets logistic scientific requirements specified for This paper provides preliminary summary meteorological, oceanographic, conditions found during experiments describes important physical biological processes that control spatial temporal changes these characteristics.
