A Deep-ocean Assessment and Reporting of Tsunamis (DART®) buoy displayed atop a metal case, which serves as an anchor. The case has a special rope coiled inside that unspools automatically when deployed. The case also has the actual pressure detector (or tsunameter) and the acoustic modem to send the data to the buoy.
