Seismic stratigraphy of the late Quaternary sedimentary infill of Lac d'Armor (Kerguelen archipelago): a record of glacier retreat, sedimentary mass wasting and southern Westerly intensification
Lac d'Armor (49 degrees 27'S, 69 degrees 42'E) is a medium-sized, fiord-type lake located on the 'Grande Terre' island of the Kerguelen archipelago. A dense grid of high-resolution reflection seismic profiles was collected from this lake basin. The seismic stratigraphic faci...
