“…The last three glacial lakes, Cambrien, Mélèzes and Minto, released four meltwater pulses exceeding 0.015 Sv into southern and western Ungava Bay around 6.0 kyr BP (Table 2), close to the final deglaciation of southern Ungava Bay [ Lauriol and Gray , 1987; Andrews et al , 1995]). The meltwater release into Ungava Bay may be related to (1) a ∼80 m thick sediment sequence in the marginal channel of the southern Ungava Bay [ MacLean et al , 1991; Andrews et al , 1995] and (2) foraminifera assemblages indicating reduced salinity and high sedimentation rates during the deposition of these sediments [ MacLean et al , 1991]. The outflow of ∼2000 km 3 of water into Ungava Bay at ∼6.5–6.0 kyr BP is likely to have caused early Holocene turbid watershed deposition along with ice‐rafted debris along the Labrador coast [ Josenhans et al , 1986; Wang and Hesse , 1996].…”

“…The prime difficulties in extending the Ungava Bay landform swarm across Hudson Strait is the lack of Proterozoic erratics in strait sediments (MacLean et al 1991;Gray 2001). However, we note that there is evidence of two advances on Baffin Island, but of at least eight individual ice streams active in Labrador-Ungava.…”

“…Comment alors expliquer l'existence d'une faune marine contemporaine à un tel événement dans le contexte régional ? La nature non perturbée des sédiments généralement stratifiés surmontant les mollusques datés dans les carottes marines dans le secteur oriental du détroit d'Hudson (Fillon et Harmes, 1982;MacLean et al, 1986MacLean et al, , 1991MacLean et al, , 1992MacLean et al, , 1993Vilks et al, 1989) n'appuie pas non plus le concept d'une phase marine interrompue par une récurrence glaciaire.…”
