The Australian Coastal Zone and Global Change: Research Needs

Australian Academy of Science, Becker House, Canberra. Friday 16 December 1994

Monitoring sea level and modelling extreme events - continued

There are 11 gauges there, and the project has the same scientific goals: that is, monitor the greenhouse effect.

OH 5: ASEAN/Australian Economic cooperation - monitoring sites

Overhead 5

This is another aid project from Australia to the ASEAN nations and there are gauges here under two different programs (Overhead 5). Originally, of course, these were all donated by Australia to these nations. The countries maintain these gauges but we get the data and we analyse and produce the tidal predictions. This is under the Regional Ocean Dynamics Project to study the through flow between the Pacific and the Indian Ocean Project. There are other gauges also.

OH 6: ASEAN/Australian economic cooperation - monitoring sites under the programmes

Overhead 6

This is another aid project to the ASEAN nations (Overhead 6). This is more to do with coastal work and various other programs, so we also have another set of gauges dealing with those.

OH 7: NTF/TOGA Network - Monitoring sites

Overhead 7

This is the network (Overhead 7) for the TOGA, which CSIRO maintained until recently. Now that the TOGA program is ending we have been asked to take over these gauges. This is the first year that we have done that and we hope to maintain it because of the importance for El Nino and other phenomena. Closer to the equator I think it is very useful to have these gauges maintained and we have every intention of doing this.

In November we entered into an agreement with the University of Hawaii to take over some of their gauges (Overhead 8).

OH 8: The University of Hawaii sea level centre and national tidal facility jointly operated gauges

Overhead 8

At the moment we have taken over four, and if the marriage works out - there is a one year trial now - we may take over the other two gauges next year.

Overhead 9

This is the final set of our gauges (Overhead 9). These are maintained by the Antarctic Division. We receive the data and we process and produce the tidal predictions.

This completes the actual sea-level data set or the sea-level instruments which the National Tidal Facility maintains. We do not necessarily operate all these, except the millimetre-accurate gauges: 11 in the South Pacific and 16 around Australia. Those are the only gauges - plus, of course, the CSIRO gauges and the Hawaii gauges - we actually maintain.

We have the gauges. These are tide gauges, that is they only record sea-level, not at the frequencies of the short period wind waves - they are filtered out, but in what you would call the long-gravity wave spectrum.
