The long-term goal of this DURIP award is to develop an ocean sensor array designed to directly measure the small-scale variability in currents and properties over the full depth of the water column, and relate this to the large-scale flow in which it is embedded. The ocean sensor array, consisting of bottom mounted Acoustic Doppler Current Profilers ADCPs and temperature-conductivity sensors, is proposed for deployment in the Mindoro sill depth 400 m and the Tablas Strait sill depth 350 m in the Philippines as part of the ONR DRI Characterization and Modeling of Archipelago Strait Dynamics . The specific objectives are to provide direct measurements of velocity and currents in narrow straits with shallow sill depths in order to 1. characterize the spatial and temporal variability of the small-scale features, 2. determine their relationship to the large-scale background flow, 3. examine how they may vary seasonally as the remote and local forcing changes . Ultimately, this will effort will provide a long-term context for the ship-borne, synoptic-type measurements during the DRI s Intensive Observing Phase IOP and furthermore, enable a better representation and prediction in numerical and theoretical models in a region that has no previous subsurface oceanographic measurements.
