This dataset contains current meter data from Prydz Bay, Antarctica. Current meters were deployed on 3 moorings around Prydz Bay between January 1986 and February 1987. Summary results and deployment details are in the documentation. Temperature and salinity were also recorded. Records are not continuous at each site over this time period. Each mooring contains three or four current meters, measuring water temperature, speed and direction, and for some meters conductivity. Moorings 1 and 2 consisted of four Aanderaa current meters with target meter deployment depths of 200m, 350m, 500 m and near bottom. Mooring 3 had three Aanderaa current meters, with depths of 200m, 350m and near bottom.

This dataset contains current meter data from Prydz Bay, Antarctica. Four moorings each consisting of four current meters were deployed at various locations in Prydz Bay. Data was obtained between January 1985 and February 1986. Each of the four current meters per mooring measured time, water temperature, speed and direction every sixty minutes. Moorings 1 and 3 also each had one current meter equipped with a pressure sensor. All meters on mooring 4 measured pressure and conductivity. The four meters on each mooring were positioned at the intended depths of 200m, 350m, 500m and near-bottom. Eleven of the sixteen current meters deployed were recovered with data intact, and summary results and deployment details are given in the documentation.

A current meter mooring was installed at the entrance of Jervis Bay, off Point Perpendicular. This mooring housed 2 current meters, at 12m and 34m. Over a period of approx. 1yr the mooring was deployed 5 times in nominally the same location (as illustrated). Deployment 1,3, 4 & 5 - 35.1 S, 150.797 E. Deployment 2 - 35.0983 S, 150.793 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.

Documentation from older metadata record: Documentation dated 2001-03-26 Mawson Submerged Tide Gauge The gauge used at Mawson was designed in 1991/2 by Platypus Engineering, Hobart, Tasmania. It was intended to be submerged in about 7 metres of water in a purpose made concrete mooring in the shape of a truncated pyramid. The gauge measures pressure using a Paroscientific Digiquartz Pressure Transducer with a full scale pressure of 30 psi absolute. The accuracy of the transducer is 1 in 10,000 of full scale over the calibrated temperature range. The overall accuracy of the system is better than +/- 3 mm for a known water density. Data is retrieved from the gauges by lowering a coil assembly on the end of a cable over a projecting knob on the top of the gauge and by use of an interface unit ,a serial connection can be established to the gauge. Time setting and data retrieval can be then achieved. The first of these gauges were first deployed Mawson in early 1992 in a a mooring in Horseshoe Harbour. The gauge was found to have some communications problems and was removed in May 1992. Tidal records from 6/3/92 to present have been retrieved from it. A new gauge was deployed at Mawson in March 1993. Data has been retrieved from these gauges irregularly since then. The records are complete since deployment except for a few days in late 1995. The loss was caused by a fault in the
