IMOS - AUV SIRIUS, CAMPAIGN: GREAT BARRIER REEF, FEBRUARY 2011

BBR昆士兰(Doherty)：在大堡礁，该项目的重点是GBR泻湖中央的海草床，以了解通过磁力通道和棕榈通道的上升流以及外部GBR上的深水珊瑚礁对海草丰度的影响。虽然对大堡礁一带的浅水礁进行了广泛的监测，但监测较深的珊瑚礁的机会相对较少。了解这些深水礁的性质可能会为了解GBR对温度变化、海洋酸化、气旋和来自海岸的营养物质流入等压力的恢复能力提供重要的见解。2011年7月完成了对泻湖海草床的调查，这些海草床旨在重访十年前使用拖曳视频调查的地点，并在大堡礁外围的Myrmidon珊瑚礁完成了调查，以在这一地区建立海底参照地点。

GBR Queensland (Doherty): In the Great Barrier Reef the program is focused on seagrass beds in the middle of the GBR lagoon to understand how their abundance is affected by upwelling coming through the Magnetic and Palm Passages and on deepwater coral reefs on the outer GBR. Although there is extensive monitoring of shallow water reefs along the extent of the GBR, there has been relatively little opportunity to monitor deeper reefs. Understanding the nature of these deepwater reefs may provide important insights into the resilience of the GBR to stresses such as changing temperatures, ocean acidification, cyclones and nutrient influx from the coast. Surveys of the seagrass beds in the lagoon, which were designed to revisit sites surveyed using towed video ten years ago, and at Myrmidon Reef on the outer GBR were completed during July 2011 to establish benthic reference sites in this area.
