Short summary
Our work provides a new coral proxy-based reconstruction of sea surface temperature (SST) from the coral reefs of Rodrigues Island, located in the poorly studied south-central Indian Ocean trade wind belt. This site is well located to study the SST history of the subtropical Indian Ocean and its teleconnections with the Pacific over long timescales. Our results provide insights into biases in coral Sr / Ca-based SST reconstructions and how to avoid them.
