91NM West of Antofagasta, Chile

NDBC station 32403 (91NM West of Antofagasta, Chile) is a moored - deep ocean DART tsunami-detection station at 23.163°S 72.037°W, operated by Cooperative Effort DART 4G. PierMonkey reads its observations straight from the NOAA National Data Buoy Center and republishes them free, with no account required to see current conditions.

It reports water-column height, the measurement tsunami detection depends on.

DART stations sit on the seafloor and measure the height of the water column above them, which is how tsunamis are detected in open ocean long before they reach a coast. The readings are far more sensitive than surface wave measurements and are reported in metres of water column rather than wave height.
