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.

The second of these six experiments concentrated on the flow patterns within the bay during the winter months, when the waters are only weakly thermally stratified. This winter mooring program was run as two deployments of current meters, from 10th July to 30th August and from 12th September to 30th October 1990, along with a meteorological station measuring winds and atmospheric pressure at Governor Head. [Given that this meteorological data bridges all six experiments, the data collected is described in a separate metadata record and will not be considered further.]

Two moorings were maintained with each deployment. In the first deployment (10/7/90 - 30/8/90) the south-central mooring contained 3 current meters and the northeast mooring 2 current meters. The second deployment (12/9/90 - 30/10/90) repeated the south-central mooring but the northeast mooring was moved south from near Green Point to off Honeymoon Bay.

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 subsidiary records that directly relate to this parent, through which the data is provided (see hierarchical tree): 6fed5f70-c336-11dc-9e24-00188b4c0af8 a1da6830-c344-11dc-9e24-00188b4c0af8 45ede7c0-c3d2-11dc-8135-00188b4c0af8 0b9e1780-c3d6-11dc-8135-00188b4c0af8
