IMOS - Deep Water Moorings - Deep Water Arrays (DA) Sub-facility, East Australian deep water array, East Australian Current 5 Mooring (EAC5) Platform

EAC 5深水系泊系统于2012年4月部署在澳大利亚布里斯班附近的昆士兰州海岸（-27.1 S，155.3 E）。2013年8月恢复系泊，阵列退役，2015年5月重新部署了新配置的阵列（配备新系泊设备），随后于2022年7月退役。 <br /> <br /> 系泊设备上的仪表包括Seabird SBE 37 SMP、温度记录仪（星星Oddi、Starmon Mini）和离散式流速计（Aquadopp 6000）。<br /> <br /> 该系泊装置将收集一系列全深度水流速度剖面图以及离散的温度和盐度测量值。<br /> <br /> 该阵列将由9个海流计和财产系泊装置组成，从布里斯班附近的昆士兰州海岸节点陆架系泊阵列向东延伸至深海。在大陆坡，系泊间距为500-600米，在深海，系泊间距增加到800-1000米。 <br /> <br /> 东澳大利亚海流（East Australian Current，EAC）是南太平洋的主要西边界流。它在海洋将全球热量从赤道重新分配到中高纬度地区的过程中起着关键作用。EAC在布里斯班以北相对稳定，但随着海流向南移动，每年都会有2-3个大漩涡被夹断。这些涡旋频繁地移到大陆架上并靠近近岸，影响当地的环流模式。在突出的海岸特征，EAC远离海岸，驱动上升流，从200米或更深的深度吸取富含营养的水。

The EAC5 deep water mooring was deployed in April 2012 at (-27.1 S, 155.3 E) off the Queensland coast, near Brisbane, Australia. The mooring was recovered in August 2013 and the array decommissioned, and a newly configured array (with new moorings) was redeployed in May 2015, and then subsequently decommissioned in July 2022. <br /> <br /> Instrumentation on the mooring includes Seabird SBE37SMPs, temperature loggers (Star Oddi, Starmon Mini) and discrete current meters (Aquadopp 6000).<br /> <br /> The mooring will collect a time series of full-depth profiles of water velocity and discrete temperature and salinity measurements. <br /> <br /> The array will consist of 9 current meter and property moorings extending eastward from the Queensland Coastal Node shelf mooring array near Brisbane to the deep ocean. The moorings will be at 500-600 m intervals across the Continental Slope and increasing to 800-1000 m in the deep ocean. <br /> <br /> The East Australian Current (EAC) is the major western boundary current of the south Pacific Ocean. It plays a critical role in the ocean re-distribution of global heat from the equator to the midand- high latitudes. The EAC is relatively stable north of Brisbane, but as the current moves south 2-3 large eddies are pinched off every year. These eddies frequently move onto the continental shelf and close inshore and influence the local circulation patterns. At prominent coastal features the EAC moves away from the coast, driving upwelling which draws nutrient-rich water from a depth of 200-m or more.
