Bluegraph – Explore NOAA buoy data, rebuilt in 3D from measured spectra

Bluegraph is an interactive visualization that reconstructs ocean conditions in 3D from measured wave spectra, charting observations from NOAA buoys, coastal stations, tide gauges and estuary sensors across two oceans, the Caribbean and the Great Lakes. It encodes significant wave height as column height and dominant period as brightness (4-16 s), aggregates 113.7 million data points collected since April 2025, and reports real-time station status (703 of 715 stations reported in the last three hours). The platform emphasizes rapid situational awareness with region filters, a scripted globe, and provision that realtime observations are provisional and not yet quality-controlled.

The interface highlights notable current readings and regional summaries: biggest seas (Western Hawaii 4.0 m, West Dixon Entrance 3.5 m, South Brooks BC 3.4 m), longest-period swell (Pauwela, Maui 15 s), strongest gusts (Wrightsville Beach Offshore 31 kt), fastest pressure falls (South Brooks BC −12.9 hPa/24 h), and localized water-level and temperature extremes (Marcus Hook +0.55 m, Bulk Terminal LA 34.0 °C). Station counts and medians are listed by region (e.g., Great Lakes 136 stations, median seas 0.2 m; Hawaii 22 stations, median seas 2.4 m), enabling quick comparison of sea state, temperature and tidal anomalies across coasts and island groups.
