Abstract

Abstract

Based on Q-mode factor analysis, living foraminifera found in samples collected throughout outer harbour of Sanya tidal inlet of Hainan island can be divided into 4 principal factor foraminifera assemblages that should represent outer harbour water mass, brackish water mass flushing from lagoon, inner shelf water mass outside harbour, and muting water mass of outer harbour and inner shelf water masses separately. The moving and intermixing of these water masses under the control of the tide can be indicated by foraminifera in them. Contour maps of the sum of the percentage contents of the taxa associated with the three highest factor scores of each foraminifera assemblage show a good fit to tidal current circulation made in outer harbour derived from oceanographic studies. The method using living foraminifera distribution as indicators of tidal current circulation model in tidal inlet, which is applied for the first time, has a high potential for analysing sediment transport, poVution discharge and so on in developing the coast meources.
