Seasonal surface and near-surface assemblages are typically unrepresentative of deeper assemblages that are more likely to be incorporated into the sedimentary record. Cluster analysis of “artificially time-averaged” (ATA) assemblages revealed a distinct change in assemblages at ~20 cm depth. Differential preservation of foraminifera in the upper 60 cm, and especially the upper 20 cm, of sediment may produce an apparent paleoenvironmental change that could potentially be misinterpreted as a rapid fall in sea-level over the last ~100–200 years.
