“…Acoustic units 1 to 6 are equivalent to units A to F of Eddy (1989). Although differing in many details, broadly similar sequences of seismostratigraphic units have been described from elsewhere around the coast of Newfoundland (e.g., Dale and Haworth, 1979;Fader et al, 1982;Shaw and Forbes, 1990b;Josenhans et al, 1990;Jenner and Shaw, 1992), from the St. Lawrence Estuary (Syvitski and Praeg, 1989), and from other marine areas in southeastern Canada (e.g., Piper et al, 1983;King and Fader, 1986;Forbes et al, 1991;Syvitski, 1992). Unit 1.…”

“…The region has continued to be a focus of surficial geological studies since the mid 1960s (e.g., Shearer, 1970Shearer, , 1973Grant, 1977Grant, , 1980Grant, , 1987Grant, , 1989aGrant, , 1991Brookes, 1969Brookes, ,1974Brookes, , 1977aBrookes, , 1977bBrookes, , 1987Brookeset al, 1985;Josenhans et al, 1990). Relative sea-level data from the area were used by Quinlan andBeaumont (1981, 1982) to constrain models of Late Wisconsinan ice loading and crustal response in eastern Canada.…”

“…The glacial marine material is mainly laminated pebbly silty clay thinly draped over till and up to 30 m thick. In the iceberg-turbated postglacial sediments to the northeast of St. Pauls Island, Josenhans et al (1990) reported pockmarks up to 6 m deep (area shown on Fig. 3) and to the northeast of the Magdalen Islands they reported on a deep "mudlump" [sic] suspected of being formed by gas migration from depth.…”

“…Most work has been done either to the north or southwest or to the east of the cape. The recent and Pleistocene geology was interpreted by Josenhans et al (1990) from cores and acoustical soundings to be either recent spill-over sands of the Laurentian Channel (over bedrock as seen in seismic line 89008 of Fig. 5) or glacial marine sediments (Fig.…”

“…O ff Comer Brook the sea floor rises steeply towards a flat-lying, shallow (-6 m) shoal at the mouth o f Humber River. The sill is composed o f ice-contact sediment (till) and is interpreted by Josenhans et al (1990) as a submarine moraine marking a major ice margin. Recent research tends to support the hypothesis that a series o f comparable submarine moraines around the coast o f south and west Newfoundland formed when ice calved across the inner shelf and attained a stable position about 14,000 l4C yr BP.…”
