Zeehan Marine Park State of Knowledge

Overview Map

Zeehan Marine Park displays low-profile platform reef across much of the shelf area. The eastern edge of the park is smooth and undulating before changing in the mid shelf to a more corrugated pavement characterised by 3-5m high ledges with flat faces. The park covers representative areas of four bioregions.

Knowledge status

Zeehan Marine Park has a medium level of knowledge.

  • The shelf reefs areas have been the focus of research efforts owing to their unique structure and potential as valuable high biodiversity habitats.
  • There have been 168 sediment samples collected from 3 surveys.
  • There are 9 publications, reports and data sets that reference the South east network and relate to Zeehan Marine Park as well as 1 publication specific to Zeehan Marine Park.
  • Depth: 91m – 5174m
  • 75.5% of seafloor mapped, most at medium resolution to support biodiversity surveys.

Key values, habitats and communities

Zeehan Rocky Limestone Reefs Source Williams Et Al

Rocky limestone reefs of varying size which support large sponges, sea whips and large soft and hard bryozoans whilst Coarse sediments provide valuable foraging grounds for crustaceans such as giant crabs2.

    Feature of interest

    Shy Albatross (Thalassarche cauta) is Australia’s only endemic albatross, with Zeehan a core foraging area for early incubating albatross from Albatross Island3.
