| Abstract: | Sea level reconstruction is an important proxy for climate change. It can be compared with other reconstructed climatic factors as well as the results of the computer model-based reconstruction to offer a better recognition of the relationship between sea-level changes and other factors in the climate system. Oxygen isotope record obtained from calcium foraminiferal shell in deep-sea sediments contains global continental ice volume signal which can be used to reconstruct the evolution of paleo-sea level. Researchers reconstructed many long time scale and continuous records of sea level change by using foraminiferal oxygen isotope ratio data. In the future of paleo-sea level reconstruction, however, researchers need to contrast the sea level reconstruction with other climate proxy results to validate its accuracy and employ the interdisciplinary study method to acquire further development. |
