(A) Sediment succession at site BBR 8 (Fig. 1; sediment log is Fig. 14 in [1]) exposing marine sediments (unit A) below terrestrial ice complex deposits (unit B). Note the pillar-like topography of the upper part of the cliff (baydjarakhs) that is due to melting of ground-ice wedges. (B) Lower part of unit A with interbedded laminated silt and fine sand, cross laminated sand with organic debris layers and overlain by a thick bed of planar parallel-laminated sand (∼37.6–40 m). (C) Interbedded laminated silt and thin sand beds, some of them as ripple form sets (starved ripples) (∼45–46 m). (D) Contact (∼48.7 m) between massive sand (unit A1) and laminated clay (unit A2). (E) Silty peat with intraformational ground-ice wedges (ice complex), unit B.
