The Jervis Bay Project was set up to undertake baseline studies of the key habitats and species in Jervis Bay on the New South Wales coast, and to develop a monitoring program to assist with long-term management of the bay. It was funded by the Department of Defence who at that time planned to relocate the fleet base of the Royal Australian Navy to Jervis Bay, and although this plan was abandoned mid-way through the study, the study was completed and the final report published in 1994.<br /> <br /> A series of 12 projects were proposed, with the 8th, 'Water Circulation of Jervis Bay' being undertaken by the Australian Defence Force Academy (ADFA). The initial aims of this 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 /> Two experiments concentrated on the flow patterns within the bay. The first during the summer months when the bay is normally thermally stratified, from 6th December 1988 to 11th January 1989, and the second during winter when thermal stratification is generally much weaker, from 10th July to 30th October 1990. Between these two experiments, moorings were maintained in the bay entrance and on the shelf, from April 1989 to April 1990, in order to investigate exchange processes between the bay and shelf waters. Further, to better understand the partition of energy from the wind through the water column, two deployments were made with an Acoustic Doppler Current Profiler that gives current time series at 1m depth intervals over most of the water column. A summer deployment of the Doppler profiler was run from December 1990 to January 1991 and a winter deployment was run from July to September 1991. Approximately once per month throughout the three year period, 1989-1991, temperature-salinity surveys were conducted within the bay and out across the shelf to provide additional information on the water exchange and circulation.<br /> <br /> Available to download through this record is a pdf outlining the structure and hierarchy of metadata records relating to this project.

杰维斯湾项目的设立是为了对新南威尔士州海岸杰维斯湾的主要栖息地和物种进行基线研究，并制定监测计划，以协助对海湾进行长期管理。这项研究由国防部资助，当时国防部计划将皇家澳大利亚海军的舰队基地搬迁到杰维斯湾，虽然这项计划在研究中途被放弃，但研究已经完成，最终报告于1994年发表。<br /> <br /> 提出了一系列12个项目，第8个项目是由澳大利亚国防军学院（ADFA）承担的“杰维斯湾水循环”项目。该项目的最初目标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 /> 两个实验集中在海湾内的流动模式。第一次是在夏季，海湾通常是热分层的，从1988年12月6日至1989年1月11日，第二次是在冬季，热分层一般要弱得多，从1990年7月10日至10月30日。在这两个实验之间，系泊保持在海湾入口和货架上，从1989年4月至1990年4月，为了调查海湾和货架之间的交换过程沃茨。此外，为了更好地了解风通过水柱的能量分配，使用声学多普勒海流剖面仪进行了两次部署，该仪器在大部分水柱上以1米的深度间隔提供海流时间序列。1990年12月至1991年1月进行了多普勒剖面仪的夏季部署，1991年7月至9月进行了冬季部署。在1989-1991年的三年期间，大约每月一次在海湾内和整个大陆架上进行温度-盐度调查，以提供关于水交换和循环的更多信息。<br /> <br /> 可通过此记录下载的是一个概述与此项目相关的元数据记录的结构和层次结构的PDF。此外，还提供了记录该研究的已发表工作文件的PDF格式。有七个子记录直接与此over-tunnel记录相关（参见层次树）：<br /> 06bf0e30-2ae3-11dd-a735-00188b4c0af8<br /> 84d67460-2ae4-11dd-a735-00188b4c0af8<br /> 5f4333e0-2ae5-11dd-a735-00188b4c0af8<br /> b146e140-2ae6-11dd-a735-00188b4c0af8<br /> c571bb80-2ae7-11dd-a735-00188b4c0af8<br /> 13391430-2ae8-11dd-a735-00188b4c0af8<br /> 629051e0-2b7b-11dd-a343-00188b4c0af8
