Much has been said about rising sea levels and predicted impacts on low lying Pacific Islands communities. As Pacific islanders, we need to be more informed about what directly affects us and our livelihoods. The population of the Pacific islands is estimated to be over 8.6 million people, most of which are coastal dwellings and therefore dependent on the ocean and its resources. So it is vital that we understand our ocean.





The Pacific Islands Applied Geoscience Commission (SOPAC), hosts the South Pacific Sea Level and Climate Monitoring Project alongside other initiatives aimed at improving our scientific knowledge of ocean and island ecosystems for the sustainable management of natural resources.
This project measures sea levels and monitors the climate in 12 Pacific Islands countries. Its main goal is to collect data and provide information to develop an accurate understanding of sea level and to develop ways to make such scientific data available to Pacific Island scountries.
More importantly, this project is at the forefront of helping to improve our understanding of our ocean and its impacts on our region, our shores, our resources and our future. Pacific Island Leaders first voiced their concern about global warming and rising sea levels at the 1988 Pacific Island Forum Meeting in Tonga.
The government of Australia responded to these concerns and embarked on developing the South Pacific Sea Level Project with Pacific partners and countries. Three years later the South Pacific Sea Level Project was ready to begin.
The project is administered and funded through the Australian Agency for International Development (AusAID) which highlights the importance of the long term commitment and investment of the Australian government to long-term data collection in our region. The Australian Bureau of Meteorology is the managing director of the project and draws on specialist expertise of the National Tidal Centre (NTC) and Geoscience Australia.(GA).
The project is hosted by SOPAC. Eighteen years and 12 Pacific Islands countries later, the South Pacific Sea Level and Climate Monitoring Project has provided an accurate data set used not only by the region but also by authors of the IPCC (International Panel on Climate Change) in its reporting on the status of global climate change.
In each of the project countries a tide gauge can be seen on the main wharf. This measures sea level, sea surface temperature, wind speed and direction and atmospheric pressure 24 hours a day, 365 days of the year.
The information collected is transmitted via satellite to the Australian Bureau of Meteorology where it is analysed and made available to the public through the project website http://www.bom.gov.au/pacificsealevel/
We are learning about the changes of regional sea levels with an unprecedented accuracy. Because we know that land movement can cause uncertainty in determining absolute sea level, a continuous global positioning system network (CGPS) has also been installed and linked to the tide gauges to measure vertical and horizontal earth movements. All of this plays an important role towards calculating absolute sea levels.
Six monthly reports containing an analysis of data collected in every country, tide prediction calendars, project brochures and fact sheets are provided to each participating country. SOPAC also uses data from this project to help undertake work such as mapping the ocean floor and monitor coastal vulnerability.
This information is vitally important for navigators, meteorologists and other weather professionals, also, environment and coastal planners, surveyors and engineers. The ultimate goal of the project is to provide environmental information to the Pacific Islands Countries and regional partners that can be applied to managing coastal environments and to enable countries to respond to extreme weather conditions.
The applications are numerous and help us to make better decisions regarding the impact on human health, water resources and marine biodiversity.
