Title: Spectra-Based Clustering for Visualizing Patterns of Ocean Waves

Abstract: The energy distribution of wind-driven ocean waves is of great interest in marine science. Discovering the generating process of ocean waves is often challenging. Typically, wave records are transformed into a wave spectrum or directional spectrum which provides information about the wave energy distribution across different frequencies and directions. Here, we propose a new time series clustering method for a series of wave spectra to extract the spectral features of ocean waves and develop informative visualization tools to summarize identified wave clusters. We also trace back when these spectra were observed, and we present colour-coded clusters on a calendar plot to show their temporal variability.
