• Coral growth rate is a physical index that is particularly closely associated with climatic factors such as Sea Surface Temperature (SST). The growth rate is minimally affected by environmental changes and serves as a high-resolution indicator in the study of climatic and environmental variation, making it a useful tool in paleoclimatic coral research. However, previous research on coral growth rate has primarily focused on the modern period, with limited investigation of the Mid-Holocene, which shares similar climatic characteristics with the current warm period. It is especially important to understand the climate and environmental conditions during the Mid-Holocene to gain insight into contemporary climate change processes and mechanisms. To address this gap, we first collected a modern Porites coral core and 23 Mid-Holocene subfossil coral cores from Tanmen, located on the eastern coast of Hainan Island. Using X-ray radiography and image processing methods, we measured and analyzed the coral growth rates
