| Abstract |
Diatoms commonly live in aquatic, naturally illuminated environments from hot-springs to wet soils, intertidal mudflats to the open ocean. As different species of diatoms tend to occupy different niches of the environment, changes in diatom assemblages have been used to infer changes in the coastal environment from freshwater to marine water conditions or vice versa. For sea-level studies, diatoms have been an important proxy for the evaluation and estimation of the indicative meaning of sea-level index points. Sea-level change is an important driving force for changes in coastal environments. There are several ways by which diatoms can help in reconstructing the amount of land-level change relative to sea level and the extent of tsunami or flood water. Despite the fact that diatoms are a useful proxy for sea-level reconstructions, there are some intrinsic problems. This situation occurs when environmental conditions have changed significantly over time in a locality. |
