Submarine Lateral Moraine in the South Central Region of Hudson Strait, Canada

  • Chapter
Book cover Glaciated Continental Margins

Abstract

Huntec DTSTM high resolution and single channel (655 cm3 air gun) seismic reflection profiles show the occurrence in south central Hudson Strait of a late glacial moraine up to 70 m in thickness. This is a constructional feature composed of acoustically unstratified, and relatively consolidated material considered to be ice-contact sediments deposited subglacially and adjacent to the margin of a glacial ice sheet. A small till tongue or local debris flow deposit occurs at the foot of the moraine.
