“…Vertical errors of sea level index points should also include: errors from levelling; angle of the borehole; measuring sample depth; extrapolating tidal range estimates over large distances or in an area with a large tidal range; overlying sediment compaction; core compaction; change in vegetation types over time; changes in the water table; uncertainty in identifying the correct tidal datum for the indicator of interest and changes in tidal regime (Devoy, 1982;Gehrels et al, 1996;Heyworth and Kidson, 1982;Massey et al, 2008;Preuss, 1979;Shennan, 1982). The magnitude of each error varies case by case, for example levelling errors are greater when sampling from a boat, than levelling on a salt marsh.…”

Keywords:Relative sea-level change; salt marsh; transfer function; diatoms; foraminifera; reconstruction; trends; Holocene; errors 2 AbstractUnderstanding late Holocene to present relative sea-level changes at centennial or sub-centennial scales requires geological records that dovetail with the instrumental era. Salt marsh sediments are one of the most reliable geological tide gauges.In this paper we review the methodological and technical advances that promoted research on 'high resolution' late Holocene sea-level change. We work through an example to demonstrate different pathways to quantitative reconstructions of relative sea level based on salt marsh sediments. We demonstrate that any reconstruction is in part a result of the environment from which the record is taken, the modern dataset used to calibrate the fossil changes, statistical assumptions behind calibrating microfossil assemblages and choices made by the researchers. With the error term of typical transfer function models ~10-15% of the tidal range, micro-tidal environments should produce the most precise sea-level reconstructions. Sampled elevation range of the modern dataset also has a strong influence on model predictive ability. Model-specific errors may under represent total uncertainty which comes from field practices, sedimentary environment, palaeo-tidal changes and sediment compaction as well as statistical uncertainties. Geological tide gauges require a detailed chronology but we must be certain that apparent relative s...

“…At the present time, the relationship of the North Wirral data to those of Cardigan Bay (Heyworth and Kidson 1982) is unclear. On the assumption that the deaths of the in situ tree stumps of North Wirral were related to a rising water table associated with rising sea-level, a smooth exponential curve linking these index points with those of Cardigan Bay would suggest that isostatic uplift in North Wirral was of the following order: c. 6500 years BP, between 2.2 and 1.9 m, c. 4000 years BP, between 0.5 and 0.0 m and c. 3000 years BP to the present, no significant uplift is evident.…”

The correlation of borehole logs, together with evidence from temporary exposures, shows the relationship between glacial deposits and the overlying Flandrian strata. The courses of buried channels in-filled with Flandrian strata have been plotted. Radiocarbon assays and pollen and diatom analyses have mainly been confined to samples taken from near the main lithological boundaries, but some radiocarbon assays have been undertaken on in situ tree stumps and on bone. New thick buried channel sequences are described, and an outline chronology from c. 6420 years BP is proposed for the Flandrian coastal sequence of the North Wirral. The data can be applied to the interpretation of sea-level change and coastal archaeology.
