Eastern Edge

This article examines naval surveying voyages undertaken between 1815 and 1860 by Phillip Parker King, Francis Price Blackwood, Owen Stanley and Henry Mangles Denham to discuss the improvements to the navigation of the Inner and Outer shipping routes along the Great Barrier Reef. The Inner Route lay between Australia’s east coast and the western edge of the reefs while the Outer Route was situated in open sea beyond the eastern edge of the reefs. These were some of the most dangerous waters for ships in the Pacific off Australia’s east coast. The article analyses the improvements to both routes resulting from the surveying of the naval commanders referred to above; it explains why the choice between the Inner and Outer routes was difficult to make; and it shows that the Outer Route was increasingly favoured by merchant vessels.

The Family

Until recently, the only sponge-associated genera in the order Zoantharia wereParazoanthus(family Parazoanthidae),EpizoanthusandThoracactis(family Epizoanthidae), both within the suborder Macrocnemina. The taxonomy of the genusParazoanthus,as originally described, has been undergoing revision since 2010, with several species, genera and even families described. In 2015, multiple molecular markers were used in combination with morphological characteristics to erect the genusUmimayanthusinside the family Parazoanthidae. It included three species described from southern Japan, with other records for some of the species from the Great Barrier Reef, New Caledonia and the Red Sea. However, little is known of its distribution in the Pacific Islands. Here we report on the finding ofUmimayanthusspecimens in Palau, Micronesia, representing the first records for this region. A total of 32 specimens ofUmimayanthuswere collected from seven different locations; eight of the specimens were identified asUmimayanthus chanpuru,while the remaining 24 colonies were only identified to genus level.

Hydrographic data from a series of cruises during 1980-1981 are used to determine the circulation in the western Coral Sea region immediately adjacent to the Great Barrier Reef. The data show flow westward towards the Great Barrier Reef, bifurcating just north of 18�S. During the monsoon season (December to February), the bifurcation point moves north to at least 14�s. The geostrophic westward flow has a subsurface maximum at a depth of about 150 m. South of the bifurcation point, the flow is south-eastward on the upper continental slope and north-eastward offshore. North of the bifurcation point, the surface flow and transport (relative to 900 dbar) are northward. However, there is sometimes a south-eastwards near-surface shear. Near the bifurcation point, the surface currents are weak and variable. All of these features of the surface flow are reflected in the paths followed by satellite-tracked drifters. Although the drifters were fixed infrequently, the drifter data indicate the possible presence of small cyclonic eddies in the region of the bifurcation. All of the satellite-tracked drifters went aground in the Great Barrier Reef within 30 days of entering the region offshore from the Reef. The data are consistent with recent models of the wind-driven circulation in the South Pacific that propose that the westward flow bifurcates at about 20�S., with 17 x 106 m3 s-1 flowing through the Indonesian Archipelago from the Pacific Ocean to the Indian Ocean.

Coral Reef System

The Great Barrier Reef is the largest coral reef system in the world. It is recognised and appreciated worldwide as a unique environment and for this reason has been inscribed on the World Heritage List. The Reef is economically-important to Queensland and Australia, supporting substantial tourism and fishing industries. Management of the Great Barrier Reef to ensure conservation of its natural qualities in perpetuity is achieved through the establishment of the Great Barrier Reef Marine Park. The maintenance of water quality to protect the reef and the industries which depend on it is becoming an increasingly important management issue requiring better knowledge and possibly new standards of treatment and discharge.
