Bluegraph turns 113.7 million NOAA buoy readings into a 3D ocean map

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

Bluegraph charts NOAA buoy, coastal, and tide-gauge data across two oceans, the Caribbean, and the Great Lakes, with 113.7 million points collected since April 2025 and 703 of 715 stations reporting in the last three hours. It rebuilds each station's measured wave spectrum in 3D, using column height for significant wave height and brightness for dominant period.
