Sedimentary and foraminiferal records of Late Quaternary environmental change west of Ireland and implications for the last British–Irish Ice Sheet

Abstract: Palaeoenvironmental change following deglaciation of the last British–Irish Ice Sheet on the continental shelf west of Ireland was investigated using multiproxy analyses of sediment and foraminifera data from nine sediment cores. Lithofacies associations record various depositional regimes across the shelf, which evolve from subglacial to postglacial conditions. Census data provide the first characterisation of benthic foraminifera populations across the continental shelf and multivariate analyses reveal three… Show more

“…A recent study of deglacial benthic foraminiferal populations from the Porcupine Bank and western Irish shelf indicates the persistence of glacimarine conditions until c. 20.9 cal ka bp on the outer shelf, and at least c. 18.5 cal ka bp on the mid‐shelf (Peters et al ., 2020). Several deep‐water cores from along the Irish margin, notably core OMEX‐2K from the Goban Spur (Scourse et al ., 2009; Haapaniemi et al ., 2010) and core MD01‐2461 from the Porcupine Saddle (Peck et al ., 2007), contain high percentages of N. pachyderma sinistral during this period, implying low sea‐surface temperatures (Fig.…”

“…The inference of high RSL and low water temperatures is supported by the presence of benthic glacimarine foraminifera and associated lithofacies in sediment cores from the Slyne Trough (see ‘Sedimentology and radiocarbon measurements’ above; cf. Peters et al ., 2020).…”
