A current meter mooring was installed in 100m of water, approximately 2km offshore of Point Perpendicular, Jervis Bay. This mooring housed 3 current meters (at 30m, 55m and 90m water depth) and also a tide gauge. Over a period of approx. 8 months the mooring was deployed 3 times in nominally the same location (as illustrated). Deployment 1 - 35.16 S, 150.817 E.
Deployments 2 & 3 - 35.1267 S, 150.825 E. Datasets presented here correspond to data retrieved from the three current meters over the study period.
The hourly datasets provide data accumulated from all 3 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) for the upper two meters at 30m and 55m water depth. The current meter at 90m utilised sampling intervals of 10mins (deployments 1 & 2) and 30mins (deployment 3). 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) 11/4/89 - 5/6/89... 2) 28/7/89 - 29/8/89... 3) 30/8/89 - 29/11/89
TIDE GAUGE: The tide gauge was secured to the mooring line on the sea-bed at a depth of ~100m for all three deployments In addition to depth, the tide gauge also housed a temperature sensor.
