In 1984 the Northern Territory Branch of AMSA, in conjunction with the North Australia Research Unit (NARU) of the Australian National University, jointly hosted a Conference on Coasts and Tidal Wetlands of the Australian Monsoon Region together with a Workshop on Coastal Management in Northern Australia. This was followed in 1987 by a Workshop on Research and Management in Darwin Harbour. The proceedings of the conference and workshops were published by NARU in their Mangrove Monograph series (No. | and No. 2, 1985; No. 4, 1988). Much of the work of marine scientists in the region has focussed on Darwin Harbour, an area that is significant not only because it is the main population centre for the Northern Territory and an important recreational and commercial resource, but also because of its unique natural features which include one of the largest single stands of mangroves in Australia. Darwin Harbour or Port Darwin is a large shallow drowned river valley system. Encompassing an area of about 1,000 square km, the Harbour is characterised by a macrotidal regime (7m spring tidal range) and an extensive shallow intertidal zone dominated by mangrove communities which extend over about 20,000 hectares in area. Subject to a strong monsoonal weather pattern, the Harbour waters are generally warm (23 to 33°C) and turbid, with heavy rainfall during the wet season (November to April) and river runoff contributing to high nutrient and sediment loads. These physical factors have a profound affect on the biota and Darwin Harbour supports a remarkably high diversity and biomass of filter-feeding benthic invertebrate assemblages. The city of Darwin lies on the north-eastern side of the Harbour. Darwin has a residential population of approximately 73,000 people. Urbanisation has developed largely around the harbour peninsula, and more recently out to the regional centre of Palmerston. Although Darwin is a capital city, it does not yet have any heavy industry and most of the environmental impacts have been concentrated near the city and East Arm of the Harbour. The major impacts have been from clearing of mangroves and infilling of intertidal land, although these are insignificant compared with southern States. While much of Darwin Harbour can be considered pristine, increased population growth, urbanisation of the shoreline and industrial development pose potential threats to the Harbour. For this reason there has been strong interest in recent years in studies aimed at providing baseline information for the future management of this large natural resource. In July 1993 the Northern Territory Branch of AMSA, together with the Museum and Art Gallery of the Northern Territory, organised an International Workshop on the Marine Biology of Darwin Harbour. This Workshop, the sixth in a series of International Marine Biological Workshops, brought together more than 30 participants from the Northern Territory, Western Australia, Tasmania, New South Wales, Canada, Indonesia, the United States, Ireland, Sweden and Denmark for 19 days of intensive study of the marine flora and fauna of Darwin Harbour. The present proceedings reports on the scientific work done at the Darwin Harbour Workshop, and includes 22 research papers. These cover the taxonomy and systematics, ecology, behaviour, and physiology and functional morphology of the marine flora and fauna of Darwin Harbour. Dr Barry C.
