Statement: Preliminary diatom analysis of the prepared slides indicate that the core contains reworked species. The presence of Actinocyclus ingens, Hemidiscus karstenii, Stephanopyxis spp, Denticulopsis spp and other non-Holocene/late Quaternary species were encountered throughout all the samples examined in the first two meters of the core.
