| Abstract |
Distinct assemblages of benthic foraminifera live at different heights above mean tide level. Analysis of modern foraminifera contained within surface sediments permits quantification of species–height relationships that can be remarkably precise (centimeter to decimeter). Armed with this knowledge, it is possible to infer the height at which a sediment sample accumulated from the foraminifera it contains. Fossil assemblages recovered from core material can be used to infer palaeomarsh-surface elevation and produce reconstructions of relative sea-level change. We review the strengths and limitations of intertidal foraminifera as sea-level indicators, and the methods used to collect, process, and analyze them. |
