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.<br /> <br /> The second of these six experiments concentrated on the flow patterns within the bay during the winter months, when the waters are only weakly thermally stratified. This winter mooring program was run as two deployments of current meters, from 10th July to 30th August and from 12th September to 30th October 1990, along with a meteorological station measuring winds and atmospheric pressure at Governor Head. [Given that this meteorological data bridges all six experiments, the data collected is described in a separate metadata record and will not be considered further.] <br /> <br /> Two moorings were maintained with each deployment. In the first deployment (10/7/90 - 30/8/90) the south-central mooring contained 3 current meters and the northeast mooring 2 current meters. The second deployment (12/9/90 - 30/10/90) repeated the south-central mooring but the northeast mooring was moved south from near Green Point to off Honeymoon Bay.<br /> <br /> As 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 is a pdf of a published working paper documenting this experiment and the results. There are four subsidiary records that directly relate to this parent, through which the data is provided (see hierarchical tree): <br /> 6fed5f70-c336-11dc-9e24-00188b4c0af8<br /> a1da6830-c344-11dc-9e24-00188b4c0af8<br /> 45ede7c0-c3d2-11dc-8135-00188b4c0af8<br /> 0b9e1780-c3d6-11dc-8135-00188b4c0af8

该记录描述了由国防部、CSIRO和澳大利亚国防学院(ADFA)开展的“杰维斯湾基线研究”项目的组成部分。该项目的最初目标是在六周的时间里获得杰维斯湾的海流和风观测，以便详细说明风力驱动的环流，并提供一个数据集，以便与同时进行的数值模拟工作进行比较。然而，在最初的实验之后，人们清楚地发现，海湾中存在着重要的洋流，而不仅仅是与直接风强迫有关。因此，必须通过测量程序和数据分析以及通过数值模拟来研究驱动流动的替代机制。结果是一系列大约六个不同的实验，旨在定义海湾周围和通过海湾入口处的水循环，了解驱动洋流的过程，并调查层化对洋流性质的影响。<br/> <BR/> 这六个实验中的第二个集中在冬季海湾内的流动模式上，当时海水只有微弱的热分层。这个冬季系泊计划是在1990年7月10日至8月30日和9月12日至10月30日两次部署海流计，并在总督海德设立一个气象站测量风速和大气压力。[鉴于该气象数据连接了所有六个实验，收集的数据将在单独的元数据记录中描述，不会进一步考虑。]<br/> <BR/> 每次部署都有两个系泊设施。在第一次部署中(1990年10月7日至1990年8月30日)，中南系泊包含3个海流计，东北系泊包含2个海流计。第二次部署(1990年12月9日至1990年10月30日)重复了中南系泊，但东北系泊从绿点附近向南移动到蜜月湾附近。<br/> <BR/> 由于这是父记录，因此没有数据可供下载。可通过该记录获得概述与该项目有关的元数据记录的结构和等级的pdf。还可以获得一份已出版的工作论文的pdf文件，该文件记录了这项实验和结果。有四条子记录与该父记录直接相关，通过它们提供数据(参见层次树)：<br/> 6fed5f70-c336-11dc-9e24-00188b4c0af8<br/> A1da6830-c344-11dc-9e24-00188b4c0af8<br/> 45ede7c0-c3d2-11dc-8135-00188b4c0af8<br/> 0b9e1780-c3d6-11dc-8135-00188b4c0af8
