| Abstract |
Coral microatolls are valuable paleo-sea-level indicators not only because of their vertical precision but also because individual coral colonies grow and respond to sea level for decades to centuries: unlike shorter-lived organisms, they contain filtered records of sea level over sustained periods. In tectonic settings, microatolls record both gradual (interseismic and postseismic) and sudden (coseismic) vertical changes. This chapter describes how to use microatolls to reconstruct relative sea-level histories. We discuss the utility and limitations of microatolls; site and sample selection; field techniques; documentation strategies; slab processing, analysis, and interpretation; dating; vertical accuracy; sources of error; and indicative meaning. |
