Abstract | The presence of streamlined glacial landforms in the submarine geological record from high-latitude fjords and channels provides evidence with which to identify the manner and direction of glacier flow
and to infer subglacial processes. Numerous linear and curvilinear elongate features extending up to 15 km in length have been recognized in Peel Sound, Canadian Arctic Archipelago. These well-preserved sedimentary landforms reflect the former
presence of a fast-flowing ice stream that flowed through Franklin Strait and Peel Sound. |
Summary | (Plain Language Summary, not published) This document displays multibeam sonar imagery Peel Sound near the junction with Franklin Strait where parallel ridges and grooves form prominent seabed
features. These linear features are up to 15 kilometres long, <1m to 27m high, and were formed by glacial processes likely during the last glaciation. The high seabed slope angles associated with these features could pose a hazard to any future
marine infrastructure in the area. |
