Application of Visual Analytics to Ocean Science: Case Studies

High resolution OGCM (Ocean General Circulation Model) reproduces various types of complex structures defined by multivariable such as warm/cold current or high/low density water mass. In order to understand such characteristic features, it is necessary to visualize and explore multivariable dataset. Therefore, we applied visual analytics, especially multi-dimensional transfer function and visual feature exploration, to represent characteristic ocean structures. Our case studies show that visual analytics is effective for understanding ocean simulation dataset.
