Iceberg Furrow Marks on the Continental Shelf Northeast of Belle Isle, Newfoundland
Side-scan sonar imagery indicates the presence of numerous large-scale furrows on the continental shelf northeast of Belle Isle, Newfoundland. The furrows are attributed to the ploughing action of bottom-dragging icebergs. They are typically linear troughs bordered by raised shoulders with an averag...
