Brief description 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 last of these six experiments consisted of a program of approximately monthly surveys of temperature and salinity distributions from within Jervis Bay, out to the edge of the continental shelf. All temperature, conductivity and pressure measurements were made using a high accuracy Neil Brown "Smart" CTD operated in a direct reading mode. The instrument was lowered and raised using a hydraulically operated winch at a speed of less than 1 m/s. Measurements were made on both lowering and raising of the CTD. 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 are some pdfs of published working papers documenting this experiment and the results. There are nine subsiduary records that directly relate to this parent, through which the data is provided (see hierarchical tree): 6d523cb0-0b78-11dd-89fa-00188b4c0af8 05818c50-14c2-11dd-bdaa-00188b4c0af8 a98cd420-14c3-11dd-bdaa-00188b4c0af8 a44b1850-15bd-11dd-9ec7-00188b4c0af8 eb65dd50-14c4-11dd-bdaa-00188b4c0af8 7e03e540-14ba-11dd-bdaa-00188b4c0af8 4919d4f0-1192-11dd-a074-00188b4c0af8 7f83d0c0-1194-11dd-a074-00188b4c0af8 0c995f90-15a8-11dd-9ec7-00188b4c0af8

Lineage Maintenance and Update Frequency: notPlanned

Lineage Statement: All temperature, conductivity and pressure measurements were made using a Neil Brown "Smart" CTD operated in a direct reading mode. The instrument was connected to an IBM compatible computer for data logging through a conducting cable via a hydraulically operated winch with electrical slip rings.
