Parent record: Water exchange processes between Jervis Bay and shelf waters

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/> 这六个实验中的第三个旨在监测海湾和大陆架之间的水交换。收集数据的时间跨度为一年，从1989年4月到1990年4月，目的是了解流量的季节性变化。在整个12个月期间，维持了3个海流计系泊设施、一个单独的验潮仪系泊设施和一个气象站。<br/> <br/> 典型的系泊部署为2个月，两次部署之间的间隔为1或2天。系泊设备重新部署在名义上相同的位置，尽管这些位置略有不同。在海湾入口处维持了两个系泊设施，一个在Point垂直方向，另一个在博文岛附近，每个都有两个海流计。第三个系泊在100米水深，在垂直点离岸约2公里处，这个系泊装置装有3个海流计和一个验潮仪。一个单独的验潮仪被保存在海湾内一个10米深的系泊中，距离博文岛200米。[鉴于从总督头桥上的气象站收集的气象数据跨越了所有六个实验，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/> 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。有四条辅助记录与该父项直接相关，通过它们提供数据(参见层次树)：<br/> 089f8080-c897-11dc-85f3-00188b4c0af8<br/> A2c0a820-c576-11dc-b888-00188b4c0af8<br/> D03f0f00-c47a-11dc-9a66-00188b4c0af8<br/> E4eaf410-d469-11dc-9644-00188b4c0af8

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
