Quantifying, Predicting and Exploiting (QPE) Uncertainty in the Southern East China Sea
Abstract
The long-term goal of this research is to develop a systematic approach to understanding acoustic uncertainty as it pertains to the passive sonar system. The approach combines measurements and modeling, and has been broken into three stages: quantifying, predicting and exploiting uncertainty. This requires an understanding of the environmental drivers of acoustic uncertainty (oceanographic, geoacoustic and bathymetric variability). To this end OASIS has conducted and will continue to study the results of acoustic transmission and ambient noise measurements in the Southern East China Sea (SECS) during two joint field studies with Taiwanese and US collaborators. The first, a pilot study, was completed in September, 2008, and the second, an Intensive Observation Period (IOP), was just completed in August and September of 2009. The acoustic measurements focused primarily on quantifying the major physical mechanisms giving rise to uncertainty in the acoustic data. Candidates evaluated included ocean mesoscale effects due to the Kuroshio Intrusion and frontal structures such as the Cold Dome, effects due to internal waves and internal tides, and spatial variability in the sea-bed and the sea surface.
