Wisconsinan Late‐glacial environmental change in Newfoundland: A regional review

Abstract: The distribution of 75 lake and bog sites, from which pollen stratigraphical evidence relevant to the late Quaternary of Newfoundland has been obtained, is presented. The detailed records of lithology, pollen and diatoms, supplemented by geochemical data, are discussed for three of the sites -Southwest Brook Lake, Woody Hill Brook Pond and Leading Tickles -and interpretations made are based on vegetational history, relative climatic changes and extent of ice cover. Radiocarbon data from 14 sites are summarised… Show more

“…EARLIEST HOLOCENE TO 8.0 KA Basal lake sediment dates =s10.2 ka on the Avalon Peninsula and on the uplands of Central Newfoundland mark the locations of ice centres which persisted until the end of the Younger Dryas oscillation (Anderson and Macpherson, 1994;Macpherson, 1982); similar evidence suggests the persistence of ice on Long Range summits until after 8 ka (J.H. McAndrews, pers.…”

“…The data set is biassed toward the lateglacial and early Holocene, as many dates were originally obtained to control the chronology of déglaciation and lateglacial events {e.g. Anderson, 1983;Macpherson and Anderson, 1985;Anderson and Macpherson, 1994). Unfortunately these dates are the most subject to error.…”

“…Sur leur carte des tendances paléoclimatiques correspondant à cette période, toutes les régions alors déglacées du Canada atlantique sont regroupées sous la rubrique 'progressive warming or stable'. Il faut admettre cependant qu'il y a très peu d'information sur cette période puisque dans l'est canadien les séquences polliniques lacustres postglaciaires ne remontent que très rarement au-delà de 12 000 BP (Anderson et Macpherson, 1994 ;Mott, 1994 ;Richard, 1994 ;Cwynar et al, 1994). Pour pallier cette lacune (au sens géologique du terme), il faut s'en remettre aux carottes océaniques, en particulier celles étudiées par de Vernal et al (1996) autour de TerreNeuve.…”

“…Les directions de l'écoulement sont fondées sur les stries et les formes profilées étudiées par Catto (1992a, 1994a, b) et Taylor et al (1994 on the Avalon Peninsula (Macpherson, 1996) indicate that deglaciation post-dated the Younger Dryas episode. Thus, there is no evidence to link Phase 3 events on the Avalon Peninsula with the climatic oscillations represented by the Younger Dryas or other amphi-Atlantic events recorded elsewhere in Atlantic Canada (Stea and Mott, 1993;Levesque et al 1993;Cwynar et al, 1994;Mott and Stea, 1995), including the mainland of Newfoundland (Anderson and Macpherson, 1994;Wolfe and Butler, 1994;Macpherson, 1995).…”
