Abstract
Since field evidence from the Frobisher Bay coast of Meta Incognita Peninsula first suggested to Miller et al. (1988) a rapid and significant re-advance of a lobe of the Laurentide ice sheet northwards from Quebec-Labrador across an ice-free Hudson Strait, between 8700 and 7900 14C yrs BP, the concept of the Noble Inlet re-advance has been further developed and defined by Stravers et al. (1992), and most recently by Manley (1995). Based on a large number of dates from Meta Incognita Peninsula, the time framework for this event has been narrowed down to 8900 - 8400 14C yrs BP. Despite a critical re-appraisal of the evidence by England and Smith (1993), on both geomorphological and glaciological grounds, the concept of a Noble Inlet re-advance across Ungava Bay from Central Quebec-Labrador has gained a measure of acceptance in the scientific community as attested to by references in recent publications of marine seismostratigraphic,sedimentological and biostratigraphic data in Hudson Strait .... The present paper re-examines the concept, based on (1) striae, flutings and till sheet data from Akpatok Island in northern Ungava Bay; (2) striae and erratic provenance data at the southeastern extremity of the Meta Incognita Peninsula, and on the Lower Savage Islands; and (3) chronological conflicts between the Meta Incognita and Hudson Strait radiocarbon date record.
