Relative sea‐level changes in the Beauly Firth have been inferred from stratigraphy, pollen and diatom analyses and by radiocarbon dating of former coastal reedswamp deposits. Using lithostratigraphic and biostratigraphic arguments for establishing the changes in coastal environment at the site, a preliminary scheme of positive and negative tendencies of sea‐level is produced. This may be related to changes in relative sea‐level. Two periods of falling relative sea‐level have been identified: (1) between c . 9,600 B.P. and c . 8,800 B.P. and (2) post c . 6,400 B.P. The period of rising relative sea‐level between c . 8,800 B.P. and c . 6,400 B.P. was interrupted briefly by a possible storm surge event which took place between c . 7,200 B.P. and c . 7,300 B.P.
