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

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
