Oblique view looking south over Ile Aux Gallet (A) with Dahlia Shoal (B) in the background. The rough relief of cobbles, boulders, and (or) outcrop occurs in water depths less than 15 m. Limestone outcrops were identified close to Ile Aux Gallet from underwater observations (Somers, 1968). Deep regions with smooth morphology (D) as well as deep pits (C) are covered with sand substrate. The vertical exaggeration is 4x and the distance across the bottom of the image is about 2.5 km.

Oblique view of Dahlia Shoal (B) looking west. The ridge at (E), which is about 940 m long, is possibly a glacial depositional feature. Sand can be seen draping the rough relief (D) surrounding the shoal. The pit in the foreground drops in water depth from 10 to 26 m from F to F'. The vertical exaggeration is 4x and the distance across the bottom of the image is about 4.0 km.
