Over-arching record: Water Circulation of Jervis Bay (Jervis Bay Baseline Studies Project 8)

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，并制定一个监测计划，以帮助对该海湾的长期管理。它是由国防部资助的，当时国防部计划将澳大利亚皇家海军的舰队基地搬迁到杰维斯湾，尽管这一计划在研究中途被放弃，但研究完成，最终报告于1994年发布。<br/> <br/> 他们提出了12个项目，其中第8个项目“杰维斯湾的水循环”由澳大利亚国防学院(ADFA)负责。该项目的最初目标是在六个星期的时间里从杰维斯湾获得海流和风的观测，以详细说明风驱动的环流，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/> 两个实验集中在海湾内的流动模式上。第一次是在夏季海湾通常处于热层结的月份，从1988年12月6日到1989年1月11日，第二次是在冬季，通常热层结较弱，从1990年7月10日到10月30日。在这两个实验之间，从1989年4月到1990年4月，在海湾入口处和大陆架上保持系泊，以研究海湾和大陆架水域之间的交换过程。此外，为了更好地了解风在水柱中的能量分配，使用声学多普勒海流剖面仪进行了两次部署，该仪器可以在大部分水柱上提供1米深度间隔的海流时间序列。多普勒剖面仪的夏季部署从1990年12月至1991年1月进行，冬季部署从1991年7月至9月进行。在1989-1991年的三年期间，大约每月进行一次温、盐度调查，以提供关于水交换和循环的更多信息。 <br/> 可通过该记录下载一份pdf，其中概述了与该项目有关的元数据记录的结构和等级。还可查阅已发表的记录这项研究的工作文件的pdf。有七个辅助记录与此总体记录直接相关(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

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.
