Most globally linked climatic records dealing with continuous longterm change are derived from the ocean sea-floors where sedimentation of microplankton is accumulated on a time scale of several centimetres per 1000 years. Variations in microfossil records over time are used as proxies for changes in the oceans.

Core E53-10 was sampled in April 1993 while visiting the Antarctic Research Facility at Florida State University. Preliminary diatom analysis of 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. Upon this observation, the core was abandoned for further study. Independent results of the zinc-silica ratio analysis performed on sub-samples also indicates an anomalous response, which is interpreted to be resultant of the reworked material incorporated in the core.

This region appears to be under a sedimentary reworked environment imposed by the drop off to the north of the South Tasman Rise.
