IMOS - New Technology Proving - Profiling Moorings Evaluation

Profiling Moorings Evaluation trialled the deployment of two different commercially available profiling mooring platforms (McLane Prawler and Delmar Wirewalker). The project aimed to determine the operational needs of these profiling systems and assess increases in sampling efficiencies and spatial resolution of data through the water column.During the assessment phase, the two profiling mooring systems were co-located in a range of ocean environments to ensure reliability and longevity over long deployment periods. The first deployment of the two systems was completed in March 2020, just south of Myrmidon Reef in Queensland by staff from AIMS and CSIRO, to test deployment in a tropical environment. The second deployment took place in inner Storm Bay, Tasmania; a temperate location, with this site similar to the conditions at the IMOS National Reference Stations at Maria Island, Port Hacking and Kangaroo Island.Subsequent deployments took place in outer Storm Bay in 500m to test the deeper profiling capabilities of both systems; and returned to Myrmidon Reef, Queensland, for final testing after improvements to system and mooring configurations.These moorings measure ocean temperature, salinity, dissolved oxygen, chlorophyll fluorescence, turbidity, photosynthesis available radiation, using instruments fixed along the mooring, and a profiler which moves along the mooring wire.

剖面锚泊系统评估项目试验了两款商用现货剖面锚泊平台（McLane Prawler与Delmar Wirewalker）的部署作业。本项目旨在明确此类剖面系统的作业需求，并评估其在水柱剖面采样效率与数据空间分辨率方面的提升效果。在评估阶段，两套剖面锚泊系统被共址部署于多种海洋环境中，以保障长周期部署下的可靠性与使用寿命。两套系统的首次布放于2020年3月完成，由澳大利亚海洋科学研究所（Australian Institute of Marine Science, AIMS）与澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）的工作人员在昆士兰州默米顿礁（Myrmidon Reef）以南海域开展，旨在测试热带环境下的布放作业。第二次布放位于塔斯马尼亚州的内风暴湾（Storm Bay），该区域为温带海域，其环境条件与综合海洋观测系统（Integrated Marine Observing System, IMOS）设置于玛利亚岛、哈克宁港与袋鼠岛的国家参考站一致。后续布放分别于水深500米的外风暴湾开展，以测试两套系统的深水剖面作业能力；在对系统与锚泊配置完成优化后，两套系统重返昆士兰州默米顿礁（Myrmidon Reef），开展最终测试。该锚泊系统通过沿锚泊缆固定安装的各类传感器，以及沿锚泊缆移动的剖面仪，对海洋温度、盐度、溶解氧、叶绿素荧光、浊度、光合有效辐射（photosynthesis available radiation）进行测量。
