DART Buoy Array early warning tsunami detection system
noun - Tsunameter is a device used to detect tsunamis, deployed across the open ocean to form a network for the purpose of early warning detection system. Tsunameters are part of a worldwide buoy array network called DART (which stands for Deep-Ocean Assessment and Reporting of Tsunamis). The purpose of the DART Buoy Array is to provide warnings in ample time for coastline communities to prepare in times of danger of inundation due to tsunamis.

The tsunameters are anchored to the ocean floor and consist of a sensor, acoustic transducer, CPU, batteries, acoustic release, and an anchor.

DART

Each node of the DART Buoy Array consists of two parts: a tsunameter positioned on the ocean floor and a surface buoy with satellite telecom capabilities. The tsunameter monitors the wave height by measuring the pressure of the water above it. Data from the nodes are sent to the World Meterological Organization's Global Telecommunications System for global dissemination over the Internet.
