Characterizing the Hydrodynamics of Jurien Bay, Western Australia
Characterizing the Hydrodynamics of Jurien Bay, Western Australia Kellie Holloway June 2006 Professor Charitha Pattiaratchi ------------------------------------------------------------------------------------- This dissertation is submitted in partial fulfillment of the requirements for the Bachelor of Engineering (Applied Ocean Science) ------------------------------------------------------------------------------------- Abstract Abstract Jurien Bay is a small town on the Central West Coast of Western Australia. With an expanding economy based on fishing, aquaculture and tourism and proximity to Perth, Jurien Bay is expected to grow rapidly over the coming years. Increasing anthropogenic pressure has the potential to compromise the currently pristine natural environment. The livelihood of the town and the economy relies on the quality of the marine environment in particular; hence it is important to understand the dynamics of the system. This study investigates the characteristics of circulation in Essex Lagoon, a deep basin to the south of the main Jurien Bay settlement. This area is a particularly important for investigation due to the future impact of the adjacent Ardross Estates development and the aquaculture zone located within Essex Lagoon. An Acoustic Doppler Current Profiler (ADCP) was deployed in summer 2006 to obtain profiles of current velocity and magnitude over three weeks in Essex Lagoon. This data complemented similar data collected during winter 2002 in Essex Lagoon and was used to carry out a seasonal comparison of currents, to characterize circulation patterns and to examine the potential for outside forcing such as atmospheric pressure systems and the Leeuwin Current to influence circulation. A distinct seasonality was found in the circulation characteristics between summer and winter and this was primarily influenced by seasonality in the wind field. -
Jurien Bay Marine Park & Turquoise Coast Islands
Periodic Assessment Report – Jurien Bay Marine Park & Turquoise Coast Islands Conservation and Parks Commission - Function The Conservation and Parks Commission’s (Commission) periodic assessments are undertaken primarily to fulfil the functions described in section 19 (g) of the Conservation and Land Management Act 1984, that is to assess the effectiveness of the implementation of management plans by those responsible for implementing them. The assessments also inform the Commission’s policy advice function to the Minister for Environment on the development of policies, amongst others, on the achievement of the purpose of the reservation of the land, for the preservation of the natural environment and the provision of facilities for the enjoyment of that environment by the community; and conservation and management of biodiversity and biodiversity components throughout the State. The periodic assessment was undertaken in accordance with the Commission’s position statement and guidelines for periodic assessments. This document is available on the Commission’s website: www.conservation.wa.gov.au.

VIII-17 West-Central Australian Shelf: LME #44
VIII East Asian Seas 321 VIII-17 West-Central Australian Shelf: LME #44 T. Irvine, J. Keesing, N. D’Adamo, M.C. Aquarone and S. Adams The West-Central Australian Shelf LME extends off Western Australia (WA) from Cape Leeuwin (~34.5°S) to Northwest Cape (~22°S). This LME owes much of its biogeographic unity to the respective connecting influences of the West Australian Current, a northward flow coming from the circulation pattern of the counterclockwise Indian Ocean gyre, and the Leeuwin Current (LC), the only west coast poleward-flowing eastern boundary current in the southern hemisphere. The LC is a major southward flow of warm, low nutrient, buoyant tropical water along this LME’s relatively narrow continental shelf, and is responsible for tropical reefs and associated marine flora and fauna flourishing further south than anywhere else in the world (CALM, 1994). In addition to these regional scale currents, there are wind-driven coastal counter currents dominating the circulation close to shore mainly during the austral spring/summer period (Pattiaratchi, 2006). Relatively high energy from sea and swell is a major feature of this LME, but there are embayments and lagoons where waves are restricted or effectively blocked, with sheltered highly biodiverse protected habitats occurring behind offshore limestone reefs in many localities (CALM, 1994). The LME has an extremely narrow shelf, in some areas being merely 40 km wide, and covers an area of nearly 550,000 km2, about 2% of which is gazetted as a marine protected area (MPA) that contains 0.37% of the world’s coral reefs (CALM, 2005a; Sea Around Us, 2007; www.dec.wa.gov.au). -

Our oceans are distinctive and diverse, home to marine life found nowhere else. Our oceans support people’s livelihoods and the Australian lifestyle. They provide places for people to watch wildlife, dive and snorkel, go boating and fish. Importantly, they create jobs in industries like fishing and tourism, and are a source of food and energy. Establishing marine parks is recognised as one of the best ways to conserve and protect marine species and habitats. In 2012, the Australian Government established 40 new marine parks around the country (formally called Commonwealth marine reserves). This was a significant achievement, expanding the total coverage of Australia’s National Representative System of Marine Protected Areas to 3.3 million km2—some 36 per cent of our oceans. Individual marine parks have been carefully located to include representative examples of Australia’s marine habitats and features. -

SHARK BAY Shark Bay Is Testimony to the Wonders of the Natural World
BAY SHARK Shark Bay is testimony to the wonders of the natural world. So significant is its natural values and beauty that the region earned a prestigious World Heritage listing in 1991. Shark Bay is famous for its friendly Monkey Mia dolphins, yet the dolphins are only one part of the remarkable Shark Bay story. Celebrating its World Heritage status, Shark Bay now offers the Shark Bay World Heritage Drive, a 130km drive commencing at the Overlander Roadhouse on the North West Coastal Highway through to Monkey Mia. The Drive encompasses the most fascinating features of the area. Here you can get in touch with the Earth’s evolutionary and biological history, its unique natural formations and seek out habitats where threatened species survive. There are few places in the world that offer so much. Discover it all on the Shark Bay World Heritage Drive. HAMELIN POOL STROMATOLITES Shark Bay is one of only two places in the world where living marine stromatolites exist. These living fossils contain microbes similar to those found in 3,500 million year old rocks – the earliest record of life on earth. As such, the stromatolites provide a record of local environmental changes. Stroll along the boardwalk, read about the history of Stumpy’s stromatolite family and take in the biology of these ancient organisms. SHELL BEACH Shell Beach, as the name implies, is not your everyday sand beach. Instead, it’s a beach made of trillions of tiny shells, all from one type of animal. The shell, known as the Hamelin Cockle, lives in prolific numbers in the area because of the super salty water.
