SouthEast Asia SEA-Level Program (SEA2)
The SouthEast Asia SEA-level program (SEA2) will integrate instrumental, historical, and geological sea-level datasets in Southeast Asia with sophisticated modeling capabilities to improve the accuracy of projections of sea-level rise and extreme sea levels, and to communicate the results to the scientific community, governmental agencies, and the public. SEA2 will assemble a multi-disciplinary team of leading experts in the fields of reconstructing past and present sea-level change, polar ice-sheet history, oceanography, geodesy, glacial isostatic adjustment (GIA) modeling, and the statistical analysis and modeling of sea-level data. Through training, the SEA2 team will build a home-grown scientific community that can respond to Singapore and Southeast Asia’s need for future sea-level projections and their interpretation.
SEA2 has identified five specific objectives to meet the challenge of understanding global and regional sea-level rise and extreme sea levels:
1. To develop a comprehensive model for regional vertical land motion – from tectonics, subsidence from groundwater withdrawal, and other solid-earth processes – that can be incorporated into sea-level projections.
2. To extend the record of sea-level change beyond the brief instrumental record to quantify regional processes.
3. To measure and model the importance of annual to multi-decadal cycles in constraining the future of extreme sea level.
4. To produce projections of global mean and regional sea-level change on policy-relevant (decadal) timescales.
5. To quantify the potential impact of sea-level rise and extreme sea level on coastal communities of Southeast Asia and develop decision support tools for protective adaptation measures.
