Sedimentology, palaeoecology and geochronology of Last Interglacial deposits from Deeping St James, Lincolnshire, England

Early Ipswichian (last interglacial) sea level rise in the channel region: Stone Point Site of Special Scientific Interest, Hampshire, England

“…These estimates are very similar to palaeotemperature estimates from Deeping St James (Keen et al, 1999 -TMax 17-18°C, TMin 0 to 4°C) and Itteringham (Beesley, 1988 -TMax 17-19°C, TMin 1 to -4°C).…”

Quaternary river terraces in England: Forms, sediments and processes

“…It is invariably erosional and therefore implies a removal of pre-existing sediment, potentially representing a considerable time interval. As noted above, the deposition of overlying coarse clastics during the last cold-stage (Devensian, Weichselian) apparently did not occur immediately after the previous interglacial but as much as 20-40 ka later (Gibbard, 1985(Gibbard, , 1994Keen et al, 1999;van Huissteden et al, 2001;Gibbard and Lewin, 2002) and we regard the interlude as dominantly a period of valley-floor excavation. If additional depositional activity did occur during this time period, little evidence for it is currently available.…”

How warm was Britain during the Last Interglacial? A critical review of Ipswichian (MIS 5e) palaeotemperature reconstructions

“…Some studies (e.g. Keen et al ., ) have argued that this approach is more valid because the northerly range of many of the thermophilous species was poorly constrained, causing T max estimates based on strict MCR estimates to be artificially low. Where LIG MCR estimates are presented, i.e .…”

“…All the beetle assemblages reported here were derived from work carried out by Coope at individual sites and summarized in a number of influential reviews. For the LIG, these studies frequently quote T max values of ∼21 °C and T min values that are the same as, or a degree or so lower than, the present day (Coope, , 2001, 2010; Keen et al ., ; Gao et al ., ). It is important to note that, with respect to Ipswichian beetle assemblages, Coope rarely used the MCR method to calculate T max and T min ranges, preferring temperature estimates based on the modern distribution of thermophilous species and a semi‐qualitative assessment of the most likely temperature values (see Coope, , 2010; Keen et al ., ; Gao et al ., ).…”
