AbstractAlbatross Bank is a flat glaciated bedrock bank (Fig. 1a) located on the distal edge of the Alaskan continental shelf south of Kodiak Island (Fig. 1b). The bank illustrates the glacial geomorphology from an active ice edge during Marine Isotopic Stage (MIS) 2 (c. 22-19 ka) sea-level regression (Briner & Kaufman 2008). The multibeam echo-sounder (MBES) images presented here provide the first detailed morphological evidence that the furthest extent of glacial advance in the late Pleistocene reached the shelf edge of the Gulf of Alaska. Other disparate areas of MBES imagery from the distal edge of the SE Alaska shelf to the western part of the Gulf of Alaska show evidence of glacial advance to the shelf break and support earlier depictions of Wisconsinan glaciation (Kaufman & Manley 2004; Briner & Kaufman 2008).
Summary(Plain Language Summary, not published)
Albatross Bank is a flat glaciated bedrock bank located on the distal edge of the central SE Alaskan continental shelf south of Kodiak Island. The multibeam echosounder (MBES) wide swath bathymetric images presented here from southern Albatross Bank provide the first detailed morphologic evidence that the furthest extent of glacial advance in the late Pleistocene reached the continental shelf edge of the Gulf of Alaska.
