OCEAN SCIENCE: Shallow Chills

Approximating Acoustic Uncertainty in Shallow Ocean Environments

In recent decades, sophisticated computational routines for underwater acoustics have been developed, and advances in computational power have put real time use of these routines in reach for sonar applications. However, the US Navy must often operate in unfamiliar waters where the basic environmental inputs to the computational routines may be uncertain or unknown. In this situation, the value...

Acoustic Techniques for Uncertainty Shallow Ocean Environments

The overall long-term goal for this project is to develop engineering tools that are useful to the Navy as it operates in uncertain and/or unknown ocean environments. During the last year, this project has changed its emphasis from predicting the impact of environmental uncertainty on acoustic propagation calculations to determining the utility of a time-reversal-based technique for source trac...

Science of Ocean Climate Models

The rich textures and features of the global ocean circulation and its tracer distributions cannot be fully studied in a controlled laboratory setting using a direct physical analog. Consequently, ocean scientists have increasingly turned to numerical models as a rational experimental tool, along with theoretical methods and a growing array of observational measurements, for rendering a mechani...
