Marine Biological Survey of the Central Kimberley, Western Australia.

1. This report describes the results of the third and final expedition to the Kimberley to document the marine flora and fauna of the area. The expedition took place in November-December 1996 with the assistance of a grant from the National Estates Grant Program.

2. Twenty-four stations were examined. Detailed notes are presented on the station locations and habitat types present. At each station algae, seagrasses, molluscs, fish, crustacea and corals were collected and notes were made on the few mangroves observed in this area.

3.Five areas of particular significance were found.

These were:
- Station 5, Hedley Island - coral pools, fish, algae and general diversity.
- Station 11, Low Water, East Montelivet - extensive coral/coralline reef flat with high diversity coral cover. Large pools, with spectacular coral cover and fish.
- Station 13, East side, Cassini Island - geomorphology and coral cover. Station 21, Wild Cat Reefs, eastern reef, west side - high algal diversity.
- Station 22, The Breakwater, Montgomery Reef - special reef.

4. This report provides an extensive section outlining the coastal geomorphology of the central Kimberley.

5. There have been no published records of the marine algae which occur in the Kimberley. This report provides details of ca. seventy species collected during the expedition. Coralline algae are poorly known and species in this group are currently being worked on taxonomically.

6. One hundred and forty four species of scleractinian corals, 292 species of molluscs, 89 species of non-caridean decapod crustaceans and 80 species of caridean shrimps, 228 species of fish and 19 barnacles were recorded. Potentially new species were found in several groups.

7. The taxonomy of many of the groups collected is poorly known. Material was obtained for specialists in particular groups in Australia and overseas. The material has been sorted and sent to the specialists for examination and determination of species. This work is complex and time consuming, so it has not been possible to provide identifications for this report. However, the material is currently being worked up and will be presented in the scientific literature when it has been completed.
