Time-series data from beacon 5 and Yarraville Shoal: 1983-1986

This record describes data from the first long-term, systematic oceanographic measurements in Spencer Gulf, South Australia. The seasonal variations of temperature and salinity, from both large-scale CTD (conductivity-temperature-depth) surveys and time-series observations at a fixed station, reveal the manner in which the gulf responds to seasonal influences. This record describes the time-series information that was obtained from a suite of instruments attached to a permanent beacon in the gulf. Initially the instruments were installed on beacon 5 (-32.7283, 137.818) in 6m of water and operated for ~6 months, from April to late October 1983. They were then immediately re-located to Yarraville Shoal (9m) where they continued their maintenance until mid-1986.

本数据集记录了澳大利亚南澳州斯宾塞湾（Spencer Gulf）首次开展的长期系统性海洋学观测数据。通过大规模CTD（导电率-温度-深度，conductivity-temperature-depth）调查与固定站位的时序观测获取的温盐季节变化特征，揭示了该海湾对季节影响的响应模式。本数据集同时收录了布设于此海湾永久信标上的整套仪器所获取的时序观测数据。初期，该套仪器被布设于水深6米的5号信标（坐标：-32.7283, 137.818），于1983年4月至10月下旬开展了约6个月的观测作业；随后随即被迁移至水深9米的亚拉维尔浅滩（Yarraville Shoal），持续运维至1986年中期。
