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 third of these six experiments was designed to monitor the exchange of water between the bay and the shelf. The data collection spanned one year from April 1989 to April 1990, in order to get an indication of seasonal variability in the flow. Throughout the 12 month period, 3 current meter moorings, a separate tide gauge mooring and a meteorological station were maintained. <br /> <br /> Typical mooring deployments were 2 months with inter-deployment gaps of 1 or 2 days. Moorings were re-deployed in nominally the same location, although these varied slightly. Two moorings were maintained in the bay entrance, one off Point Perpendicular and one off Bowen Island, each containing two current meters. A third mooring was in 100m water depth, approximately 2km offshore of Point Perpendicular and this mooring housed 3 current meters and a tide gauge. A separate tide gauge was maintained in a mooring in 10m of water, 200m off Bowen Island, inside the bay. [Given that meteorological data collected from the station on Governor Head bridges all six experiments, the data collected is described in a separate metadata record and will not be considered further.]<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 subsiduary records that directly relate to this parent, through which the data is provided (see hierarchical tree): <br /> 089f8080-c897-11dc-85f3-00188b4c0af8<br /> a2c0a820-c576-11dc-b888-00188b4c0af8<br /> d03f0f00-c47a-11dc-9a66-00188b4c0af8<br /> e4eaf410-d469-11dc-9644-00188b4c0af8

本记录描述了由国防部、CSIRO和澳大利亚国防军学院（ADFA）进行的“杰维斯湾基线研究”项目的组成部分。该项目的最初目的是在六周内从杰维斯湾获得海流和风观测结果，以详细说明风力驱动的环流，并提供一组数据，用于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，很明显，海湾中有明显的海流，不仅仅与直接的风力有关。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。结果是一系列的大约六个独立的实验，旨在定义海湾周围和海湾入口的水循环，以了解驱动电流的过程，并调查分层对电流性质的影响。<br /> <br /> 这六个实验中的第三个旨在监测海湾和大陆架之间的水交换。收集的数据从1989年4月至1990年4月，历时一年，以了解流量的季节性变化。在整个12个月期间，维护了3个流速计系泊设备、一个单独的验潮计系泊设备和一个气象站。<br /> <br /> 典型的系泊部署为2个月，部署间隔为1或2天。系泊设备在名义上的同一地点重新部署，尽管这些地点略有不同。在海湾入口处有两个系泊设备，一个在Percepular点附近，一个在Bowen岛附近，每个都有两个海流计。第三个系泊处水深为100米，距离Point Percubular离岸约2公里，该系泊处设有3个流速计和一个验潮仪。一个单独的验潮仪保持在一个停泊在10米的水，200米以外的鲍恩岛，在海湾内。[鉴于从Governor Head站点收集的气象数据连接了所有六项实验，因此收集的数据在单独的元数据记录中描述，将不再进一步考虑。] <br /> <br /> 由于这是父记录，因此没有数据可供下载。通过该记录可以获得概述与该项目相关的元数据记录的结构和层次结构的PDF。另外还提供了一份已发表的工作文件的PDF格式，记录了这个实验和结果。有四个子记录直接与此父记录相关，通过这些子记录提供数据（参见层次树）：<br /> 089f8080-c897-11dc-85f3-00188b4c0af8<br /> a2c0a820-c576-11dc-b888-00188b4c0af8<br /> d03f0f00-c47a-11dc-9a66- 00188b4c0af 8<br /> e4eaf410-d469-11dc-9644-00188b4c0af8
