AbstractAll inlets and fjords on northern Baffin Island record glacial erosion by outlet glaciers (Shepard 1931; Pelletier 1966). However, their positions were probably influenced by prior fluvial erosion (Fortier & Morley 1956; Pelletier 1966; Gilbert 1982) or by graben-style faulting (Andrews & Miller 1979; Gilbert 1982; Dowdeswell & Andrews 1985; England 1987). Navy Board Inlet is a narrow waterway (about 10 km wide) located south of Lancaster Sound between Baffin Island and Bylot Island in Arctic Canada (Fig. 1). Lineations formed by the movement of glacial ice are preserved on the seafloor of this inlet.
Summary(Plain Language Summary, not published)
Lancaster Sound was occupied by glaciers that were over 1600 m thick during the last glaciation. All inlets and fiords on northern Baffin Island have been eroded by glaciers in the past. This erosion has been studied extensively on land but marine research has been lacking. Navy Board Inlet is a narrow waterway (about 10 km wide) located south of Lancaster Sound between Baffin Island and Bylot Island. Linear erosion marks formed by the movement of glaciers are preserved on the seabed of this inlet.
