A device and process is disclosed for creating detailed volumetric ocean els, which in turn are used as inputs for naval tactical and oceanographic analysis. Near-real-time volumetric modelling is accomplished by continuously integrating, filtering, interpolating, and extrapolating oceanographic data (e. g. , temperature, sound velocity, conductivity, salinity, bathymetry, current, chlorophyll) from historical data bases, forecasts, remote sensors, and onboard sensors. The value of the invention can be appreciated in the detailed, time-varying, three-dimensional ocean models which can be realized for mesoscale and smaller areas and the ability to use these more detailed and timely ocean models for three-dimensional acoustic propagation predictions and combat control algorithms. Tactical and oceanographic models are computed using an advanced processor and the results are displayed using three-dimensional visualization softwaare and hardware techniques. The invention may be used from a submarine, surface ship, or aircraft.
