Visual Analytics interfaces allow ocean scientists to interactively investigate and compare different runs and parameterizations. However, oceanographic models are complex, temporal and the datasets that are generated are huge. Parallel Coordinate Plots can help explore multivariate data such as ocean-science data. Common issues with traditional PCPs of clutter and performance inhibit interactive spatial exploration. We describe techniques that aggregates the PCP based on the spatial nature of the data and we render the polylines as ranges.
