The National Data Buoy Center's network of Deep-ocean Assessment and Reporting of Tsunamis (DART®) stations report water-column height and are used for validating whether subsurface earthquakes have generated tsunamis.

The DART II surface buoy, shown in Figure 5, relays information and commands from the tsunameter and the satellite network. The buoy contains two identical electronic systems to provide redundancy in case one of the units fails.

The surface mooring uses a 2.5 m diameter fiberglass over foam disk buoy with a gross displacement of 4000 kg. The mooring line is 19 mm 8-strand plaited nylon line with a rated breaking strength of 7100 kg and is deployed with a scope of 0.985.

Apr 7, 2025 · National Data Buoy Center - Recent observations from buoy 44091 (39.768N 73.770W) - Barnegat, NJ (209).

A near real-time prototype tsunami reporting system has been designed using a surface buoy moored over a BPR as a relay point for tsunami data. It is not practical for technical reasons to make an electrical connection from the sea floor to the surface to transmit data.

Since that time, the array has been the centerpiece of an international climate study with nearly 70 surface buoys in the TAO array spanning the Pacific from approximately 8°N to 8°S from longitudes 137°E to 95°W.
