IMOS - South-East Queensland 200m (SEQ200) Mooring Platform

The South-East Queensland 200m mooring (IMOS platform code SEQ200) is part of the East Australian Current (EAC) array. It was initially deployed on the 25/03/2012 at (27.34 S, 153.77 E). The site depth is 200m.\n\nObservations of currents, temperature, and conductivity are measured.\n\nIn conjunction with the SEQ400 mooring and the North Stradbroke Island National Reference Station (NRS NSI), this mooring forms the inshore component of the the EAC mooring array. 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 200m or more. \n\nManagement of this mooring is undertaken by staff from the National Reference Station (North Stradbroke and Maria Island).

南昆士兰州东南部200米锚系潜标（IMOS平台代码SEQ200）隶属于东澳流（East Australian Current, EAC）阵列。该潜标于2012年3月25日首次部署在南纬27.34°、东经153.77°的海域，该站点水深为200米。

该潜标可测量海流、海水温度及电导率参数。

该锚系潜标与SEQ400锚系潜标、北斯特拉德布罗克岛国家参考站（North Stradbroke Island National Reference Station, NRS NSI）共同组成东澳流锚系阵列的近岸组成部分。东澳流（EAC）是南太平洋的主要西边界流，在全球热量从赤道向中高纬度的海洋再分配过程中发挥关键作用。布里斯班以北海域的东澳流相对稳定，但当该海流向南延伸时，每年会形成2-3个脱离主海流的大型涡旋。这些涡旋常会侵入大陆架并向近岸汇聚，进而影响局地环流格局。在典型海岸特征区域，东澳流会偏离海岸，引发上升流，将200米及更深层的富营养海水抽吸至上层海域。

本锚系潜标的运维管理工作由国家参考站（北斯特拉德布罗克岛与玛丽亚岛）的工作人员承担。
