The Observations Network Upgrade Project (ONUP) was developed in collaboration with Australian Aid and Geoscience Australia (GA) and is currently refurbishing and upgrading the measurement and communication technology at 12 South Pacific sea level stations.

The objective of ONUP is to maintain the existing capacity to measure, record and transmit high quality sea level data for a further 10 to 15 years. From 2010-2012, the project successfully upgraded sea level stations in Tonga, Fiji, Samoa, Cook Islands, Solomon Islands, Vanuatu, Palau, Micronesia, Marshall Islands, and Kiribati. In 2013, stations in Tuvalu and Nauru will be upgraded and the ONUP project completed.

In addition, the ONUP team commissioned a ‘test station’ at the Bureau of Meteorology’s Training Centre, allowing Bureau staff to fully field-test the operation of electronic systems and data communications equipment destined for use in the upgrade.
