A current meter mooring was installed at the entrance of Jervis Bay, just off Bowen Island. This mooring housed 2 current meters, at 12m and 30m. Over a period of approx. 1yr the mooring was deployed 5 times in nominally the same location (as illustrated). Deployment 1 - 35.11 S, 150.78 E. Deployments 2->5 - 35.11 S, 150.772 E. Datasets presented here correspond to data retrieved from the two current meters over the year.

The hourly datasets provide data accumulated from all 5 deployments, and provide details of the eastern & northern tidal components, cross & long-shore velocity components, temperature, salinity and sigma-T.

The subsets to these larger datasets, present individual data points collected at sample intervals of 10 mins (deployment 1) or 15 mins (deployments 2, 3, 4, 5). Compared to the hourly averaged datasets, these allow water movements to be studied over a shorter time scale. The parameters measured include the eastern and northern tidal components, water speed and direction, temperature, salinity and sigma-T.

Approx deployment dates - see individual records for exact date and time of collection: 1) 5/4/89 - 4/6/89... 2) 23/6/89 - 28/8/89... 3) 30/8/89 - 13/11/89... 4) 14/11/89 - 29/1/90... 5) 31/1/90 - 28/3/90

TIDE GAUGE: The tide gauge was secured to the mooring line on the sea-bed at a depth of ~35m during the first deployment. Curiously, additional tidal data was gathered from this approximate location (see record for exact coordinates) after the final deployment, between 28/3/90 and 12/7/90. The height of the tidal gauge was also raised to 10m for this additional deployment. In both datasets the tide gauge recorded temperature as well as depth.

This is one of four child records that relate to the parent, 5f4333e0-2ae5-11dd-a735-00188b4c0af8. A pdf outlining the structure and hierarchy of all metadata records relating to this project is available to download through this record. Also available is a pdf of a published working paper documenting this experiment and the results.
