Integrated Ocean Dynamics and Acoustics (IODA)<\/h1>\n

DoD MURI ocean research project website<\/strong><\/p>\n

Project Overview<\/h3>\n

Long Term Goal:<\/strong>\u00a0IODA is an integrated ocean fluid physics and acoustics study with the goal of creating a broadly applicable and portable continental shelf-area acoustic prediction capability that includes the effects of internal and surface gravity waves as well as effects of subtidal large-scale processes.<\/p>\n

Objective:<\/strong>\u00a0The objective is to improve ocean physical state and acoustic state predictive capability. Specific short-term project objectives are the completion of targeted studies of the relevant oceanographic processes, acoustic propagation processes, and acoustic scattering processes, plus the development of improved computational tools for the physical regimes identified to be important.<\/p>\n

The motivation for the project is that regional environmental modeling and acoustic or sonar modeling can occur in disconnected fashion. If the environmental models are optimized for other purposes, they may not provide environmental inputs that are essential to predictive acoustic models. Research into what the relevant environmental factors are, and how to best model them, and how to pass the information to acoustic models are important thrusts of the project.<\/p>\n
