南澳大利亚斯宾塞湾第一个长期、系统的海洋学测量计划的结果进行了描述。该海湾属于半封闭海洋的一个子集，其特征是净流体损失（在这种情况下是由过度蒸发引起的）以及由此产生的环流，与经典河口中发现的环流相反。在斯宾塞湾，这种逆河口特征导致夏末河口盐度高达 48。来自大规模 CTD 调查和固定站时间序列观测的温度和盐度的季节性变化揭示了海湾对季节影响的响应方式。根据这些信息，定量评估了海湾的分散能力，并讨论了温盐过程对海湾-海洋交换的影响。
Results are described from the first long-term, systematic program of oceanographic measurements in Spencer Gulf, South Australia. The gulf belongs to a subset of semi-enclosed seas that are characterized by a net fluid loss, in this case induced by excess evaporation, and a resulting circulation that is the reverse of that found in a classical estuary. In Spencer Gulf, this inverse estuary character involves the production of salinities as high as 48 at the head in late summer. The seasonal variations of temperature and salinity, from both large-scale CTD surveys and time-series observations at a fixed station, reveal the manner in which the gulf responds to seasonal influences. From such information, the gulf's dispersive capabilities are quantitatively assessed, and the implications of thermohaline processes for gulf-ocean exchange are discussed.
