Satellite-derived bathymetry of Funafuti Atoll, Tuvalu


High-resolution visible satellite imagery (Quickbird) was acquired and a physics-based model inversion process used to estimate water column depth. The methodology for this project and assessments of accuracy are extensively report by Botha (2012) and Botha et al. (2013). This dataset has not been approved for general release.

LineageQuickbird satellite data, other bathymetric survey data provided by SPC-SOPAC

CreditDigital Globe: Quickbird satellite data. This data collection is a product is funded and supported by the Australian Government through the Pacific Australian Climate Change Science and Adaptation Planning Programme (PACCSAP). PACCSAP was funded by Department of Foreign Affair & Trade, managed by the Department of the Environment and the science was delivered by the partnership between CSIRO and the Bureau of Meteorology.

This output was produced as part of PACCSAP Project 1.4.4: Understanding the effect of climate variability and climate change on extreme sea levels and coastal impacts.

Project DescriptionThis activity builds on extreme sea level research undertaken during the PCCSP. Historical extreme sea level events known to cause erosion and inundation will be analysed at selected locations across the Pacific. Projections of extreme sea level events will be assessed for Fiji and Samoa. Wave transformation during extreme sea level events will be examined across Funafuti atoll (Tuvalu).
