California Current Monitoring Using the NPS Ocean Acoustic Observatory

Abstract : The long-term research goals are: 1. To achieve a permanent, real-time capability in monitoring the meso- to large-scale temperature variability off Central California using decommissioned SOSUS arrays as receivers in a tomographic system. 2. To understand the physics and variability of long-range, low-frequency sound traveling initially downslope from a seamount, through the California Current Front over deep water, and then upslope through inshore waters. Important questions to be addressed are: What role does each of the three geographical regimes play in the composition of the received signal?
