Overview Map

Murray Marine Park contains highly varied geomorphology throughout the park, potentially encompassing many shelf reef habitats. The northern edge consists predominately of Lacepede shelf, a large shelf area intersected by ancient channels of the Murray River that converge at the head of Sprigg canyon on the continental shelf2. It covers representative areas of four bioregions.
