Tide gauges provide the most direct observational record of extreme sea levels at the coast.
We have recently released Canute 3.0, a sea level calculator for projections based on tide gauges or climate model data, combined with statistical analysis. This tool is in the final stages of development and testing on a new platform (Rshiny) and with additional data sets. The previous version, Canute2, operated by the Antarctic Climate & Ecosystems CRC also remains available at this time. Please note each version has a separate registration process.
CoastAdapt contains regional information on extreme sea levels, including future sea level rise for every coastal local council in Australia.
