Australia Highseas
These deep waters lie south of Kangaroo Island, beyond the edge of Australia's southern continental shelf. The Murray submarine canyon system cuts the slope to the north of this position, its channels carrying sediment towards the deeper ocean. The canyons can also help bring nutrient-rich water up the slope. Sperm whales forage along the shelf break and in the waters south of Kangaroo Island, where the seabed falls away from the continent.
