Cartoons showing BIS terminus position within the trough at positions A–C identified on seismic profile in Fig. 3b and paleoenvironmental conditions recorded by sedimentary facies on the continental slope at Site U1421. a Maximum advance with terminus at shelf edge. b Terminus fluctuates between A and B. c Terminus readvance from C to A with formation of ice-contact delta filling inner shelf basin. d Complete retreat with terminus landward of C.
