Parent record: Temperature salinity (CTD) profiles conducted within Jervis Bay and out across the shelf

This record describes components of the 'Jervis Bay Baseline Studies' project conducted by the Department of Defence, CSIRO and Australian Defence Force Academy (ADFA). The initial aims of the project were to obtain current and wind observations from Jervis bay over a six week period in order to detail the wind driven circulation and provide a data set for comparison with the numerical modelling work being simultaneously undertaken. However, after this initial experiment it became clear that there were significant currents in the bay that are not simply related to direct wind forcing. Therefore, alternative mechanisms for driving the flow had to be investigated, through the measurement programs and data analysis, as well as through numerical modelling. The result was a series of approximately six separate experiments aiming to define the water circulation around the bay and through the bay entrance, to gain an understanding of the processes that drive the currents, and to investigate the influence of stratification on the nature of the currents.\n\nThe last of these six experiments consisted of a program of approximately monthly surveys of temperature and salinity distributions from within Jervis Bay, out to the edge of the continental shelf. All temperature, conductivity and pressure measurements were made using a high accuracy Neil Brown "Smart" CTD operated in a direct reading mode. The instrument was lowered and raised using a hydraulically operated winch at a speed of less than 1 m/s. Measurements were made on both lowering and raising of the CTD.\n\nAs this is a parent record, no data is available to download. A pdf outlining the structure and hierarchy of metadata records relating to this project is available through this record. Also available are some pdfs of published working papers documenting this experiment and the results. There are nine subsiduary records that directly relate to this parent, through which the data is provided (see hierarchical tree): \n6d523cb0-0b78-11dd-89fa-00188b4c0af8\n05818c50-14c2-11dd-bdaa-00188b4c0af8\na98cd420-14c3-11dd-bdaa-00188b4c0af8\na44b1850-15bd-11dd-9ec7-00188b4c0af8\neb65dd50-14c4-11dd-bdaa-00188b4c0af8\n7e03e540-14ba-11dd-bdaa-00188b4c0af8\n4919d4f0-1192-11dd-a074-00188b4c0af8\n7f83d0c0-1194-11dd-a074-00188b4c0af8\n0c995f90-15a8-11dd-9ec7-00188b4c0af8

本记录详述由澳大利亚国防部、澳大利亚联邦科学与工业研究组织（CSIRO）以及澳大利亚国防学院（ADFA）共同开展的“杰维斯湾（Jervis Bay）基线研究”项目的相关组成部分。该项目最初的目标为在六周周期内获取杰维斯湾的海流与风况观测数据，以详细阐明风驱动环流机制，并提供数据集用于与同期开展的数值模拟工作进行比对。然而，在初始实验完成后，研究人员发现该海湾内存在显著海流，其并非简单与直接风力强迫相关。因此需通过测量计划、数据分析结合数值模拟手段，探究驱动该环流的其他潜在机制。最终该项目衍生出共计约六组独立实验，旨在明确海湾周边及湾口的水体环流特征，明晰驱动海流的物理过程，并探究层化效应对海流特性的影响。

上述六组实验中的最后一组，实施约每月一次的普查计划，对杰维斯湾内部直至大陆架边缘的海域开展温度与盐度分布观测。所有温度、电导率及压力测量均采用高精度尼尔·布朗（Neil Brown）"Smart"型CTD（温盐深剖面仪），以直读模式完成作业。该仪器通过液压绞车以低于1米/秒的速度完成下放与回收，且在仪器下沉与上浮的全过程中均同步采集数据。
