Sea level station upgrades improve tsunami and climate preparedness

Tuesday, 12 November 2013, Secretariat of the Pacific Community (SPC), Suva, Fiji –  On the old main wharf in Funafuti, Tuvalu, few passers-by normally stop to take note of the tall white hut that juts out over the lagoon. For the last two weeks, however, this hut- one of 14 similar dockside huts across the Pacific that monitor sea level and weather conditions- has been buzzing with activity as regional technicians work to upgrade the sensors, power, and data communications systems housed within.

The completion of this work in Tuvalu represents the successful conclusion of a 2-year project funded by the Australian Government to improve sea level and climate monitoring across the region.

‘The sea-level stations always collected data continuously, but only transmitted the data every hour,’ explains Stamy Criticos, logistics and installation manager from the Australian Bureau of Meteorology.  ‘With the upgrade, the network of 14 stations are now transmitting every minute and will soon be able to provide real-time data to meteorologists around the Pacific. It will also be used to enhance tsunami  tracking and warning systems.’

Known as the Observation Network Upgrade Project (ONUP), this project is boosting the capability of the Pacific Sea Level Monitoring Project, which has collected data from 14 sites across the Pacific since 1991.  This data is used to understand sea-level changes and is frequently referenced for coastal development work, urban planning, tidal predictions, formulation of maritime boundaries, wave modelling and for navigational purposes.

For example, Ms Melina Ailesi, a technician and GIS officer for Tuvalu Telecom, reports that the sea level data is ‘the most important data’ she uses in her work. ‘I plan the network plan for our cables,’ she explains, ‘and tide data is very important to us. Funafuti experiences a lot of high tides every month and the most affected area is where our underground infrastructure is. That’s why I need this data, because if it’s high tide I can see how our assets are affected.’

When asked to comment on the sea level monitoring project, Permanent Secretary of Foreign Affairs Mr Tapugau Falefou notes that, ‘As decision makers, we need technical advice that is relevant, up to date, and accurate. Tuvalu is one of the most vulnerable countries to sea-level rise, and decisions based on inaccurate information can be disastrous to the country. I strongly see the importance of this project to be continued.’

The Australian Bureau of Meteorology’s Climate and Oceans Support Program in the Pacific (COSPPac) manages the sea-level monitoring project with technical and project support from the Secretariat of the Pacific Community’s Geoscience Division (GSD).

Newsflash

The annual Pacific Geographic Information System and Remote Sensing (GIS/RS) User Conference will be held from Tuesday 25 - 27 November, 2014 in Suva.

The Conference will be held at the Japan Pacific ICT Centre located at the University of the South Pacific (USP), Laucala Campus and will be opened by the Permanent Secretary of Lands, Mr Tevita Boseiwaqa and the Secretariat of the Pacific Community’s (SPC) Applied Geoscience and Technology Division Director, Professor Michael Petterson.

The theme of the 2014 Conference is “Empowering Pacific Communities through Improved Geospatial Data” where more than 200 participants are expected to converge.

The three-day conference will include plenary presentations and technical sessions to address themes that include but are not limited to using GIS in forestry and landcover, coastal and marine, spatial open source data, disasters, geodetic infrastructure, utilities, and education with case studies from Pacific Island countries. The conference will also showcase the latest technology and applications on GIS presentations.

Dr Wolf Forstreuter, Head of SPC’s GIS/RS Unit commented that this is the only conference in the GIS & RS user community where Pacific Islanders have an opportunity to showcase their GIS & RS applications and meet representatives of spatial data resellers, software, hardware vendors, and scientific specialists. He added, ‘There are some regional conferences in Hawaii, New Zealand and Australia; however, the level of participation by representatives from the Pacific region is often limited at those meetings, as compared to the Suva conference.’
