Australia's Coral Sea - How Much Do We Know?
Proceedings of the 12 th International Coral Reef Symposium, Cairns, Australia, 9-13 July 2012 18E The management of the Coral Sea reefs and sea mounts Australia's Coral Sea - how much do we know? Daniela M. Ceccarelli 1 1PO Box 215, Magnetic Island QLD 4819 Australia Corresponding author: [email protected] Abstract. Recent efforts to implement management zoning to Australia’s portion of the Coral Sea have highlighted the need for a synthesis of information about the area’s physical structure, oceanography and ecology. Current knowledge is hampered by large geographic and temporal gaps in existing research, but nevertheless underpins the determination of areas of ecological value and conservation significance. This review draws together existing research on the Coral Sea’s coral reefs and seamounts and evaluates their potential function at a regional scale. Only four coral reefs, out of a potential 36, have been studied to the point of providing information at a community level; this information exists for none of the 14 mapped seamounts. However, the research volume has increased exponentially in the last decade, allowing a more general analysis of likely patterns and processes. Clear habitat associations are emerging and each new study adds to the’ Coral Sea species list’. Broader research suggests that the reefs and seamounts serve as dispersal stepping stones, potential refugia from disturbances and aggregation hotspots for pelagic predators. Key words: Isolated reefs, Dispersal, Community structure, Refugia. Introduction Australia’s Coral Sea lies to the east of the Great Barrier Reef (GBR) within the Australian EEZ boundaries. Geologically, it is dominated by large plateaux that rise from the abyssal plain and cover approximately half of the seabed area (Harris et al. -

Ocean legend Valerie Taylor separates truth from tall tales. I’M OFTEN REFERRED TO as a scientist. I’m not. I write from 65 years of experience. The oceans have been very good to my husband Ron and me. They’ve given us a life of excitement and adventure. The marine world is my teacher, my workplace, and my love, yet Ron and I have but dabbled in what it offers–unknown depths and their mysterious creatures, covering 72 per cent of our planet’s surface. Ron and I learnt very early that footage of sharks would sell more readily than that of any other marine animal. In the 1950s Movietone News (an international cinema-shown newsreel covering the years 1929–79) bought Ron’s 16 mm footage, blew it up to 35 mm and showed it in theatres around the world. Then came television (in 1956 in Australia) and the public’s lust for any images of sharks had us searching offshore waters for these “dangerous” predators. For us, filming sharks in their natural environment became a way of life. Much of my first-hand knowledge was acquired in the 1980s when using the mesh suit. There’s no easy way to describe sharks. There are hundreds of species, all with different characteristics, but few of them are potentially dangerous to humans. The most threatening species cruising our coastline is the white shark. -

The portion of the Coral Sea within Australian waters is the area of ocean between the seaward edge of the Great Barrier Reef Marine Park (GBRMP), the limit of Australia’s Exclusive Economic Zone (EEZ) to the east, the eastern boundary of the Torres Strait and the line between the Solitary Islands and Elizabeth and Middleton Reefs to the south. -

December 2008 Milestone Report
MTSRF Milestone Report Project 1.1.2 – December 2008 Marine and Tropical Sciences Research Facility (MTSRF) December 2008 Milestone Report Project 1.1.2– Status and Trends of Species and Ecosystems in the Great Barrier Reef. Project Leader: Jos Hill, Reef Check Australia. Summary This report summarises the dive operator interpretation materials developed. For reference: Milestone extracted from Project Schedule The milestone task is to report on finalised operator interpretation materials (with appropriate attribution of MTSRF funding)Project Results Description of the results achieved for this milestone This section should include a short statement assessing whether the project is ‘on track’ or not. If not on track then the details of the issues for the project can be elaborated in the section below on ‘Forecast Variations to Milestones’. This project is currently on track. Activities include Finalisation of interpretation materials for the dive operators that are contained within an Operator Information Pack which is a folder on board the supporting dive boats that contains information about Reef Check, sites monitored and a back catalogue of newsletters: Information brochure: this brochure was funded by Envirofund (pdf attached). Brochures will be available for tourists to take home from their dive trip. Information booklet: the information booklet was in part funded by MTSRF (RRRC) and GBRMPA (see link: http://andrewharvey.xsmail.com/Reef%20Check%20flip%20chart.pdf Content for the information booklet has been finalised. It is currently being reviewed and will have typos fixed mid December in time for printing and distribution during 2009. Volunteers will also update the Operator Information Packs with copies of the latest Reef Check Australia newsletters as requested by dive operator managers in the 2008 feedback survey.
