Impacts of short-time scale water column variability on broadband high-frequency acoustic wave propagation
… are viable as a remote sensing tool to measure oceanographic parameters in shallow water. First, coherent surface reflections forming striation patterns, from multipath receptions, through rough surface interaction of broadband acoustic signals with the dynamic sea surface are analyzed. Matched …

Late quaternary sedimentation in the Eastern Angola Basin
… rise revealed major fluctuations in the surface oceanographic conditions, primary productivity, and near-bottom depositional environment during the late Quaternary. Sediments deposited during glacial intervals contain markedly lower carbonate, higher levels of organic carbon, and more abundant …
