TSUNAMETER IMPROVEMENT

DART II TECHNOLOGY

PMEL-recommended modified electronics to reduce false

alarms and spiking due to acoustic feedback Mooring analysis to reduce mooring failures

Easy To Deploy (ETD)

Participating in the validation of proposed GTS/BUFR

format for real-time messages as requested by AustralianBureau of Meteorology (this is an international formatused by Envirtech Buoys too)

The software functionalities provided by theUM are as follows:

3 operations state: Maintenance Mode,Normal Mode, Alarm Mode;

In Normal Mode the software acquires, logsand processes every 15 seconds pressure

data to detect events over the normal tidesignal; Automatic switch in Alarm Mode in case of

detection of an event and automatic sending

of pressure data via acoustic link; Return to Normal Mode after 3 hours
