| Summary: | Progress Code: completed Statement: See the data download for more details. Each tide gauge typically encountered some problems throughout its life, resulting in data gaps, or poorer quality data. For example, there is a gap from January to June 2000 and from 20-23 November 2003. There will be a large gap in the datset after the time the gauge ceased to function as the gauge was not immediately replaced. These data have been through an extensive 'clean-up' to improve their quality as much as possible (see the document in the download file). Purpose Measurement of tides and determination of sea levels. Over time there have been a number of tide gauges deployed at Casey Station, Antarctica. The data download files contain further information about the gauges, but some of the information has been summarised here. Note that this metadata record only describes tide gauge data from 1996 to 2007. More recent data are described elsewhere. Old Tide Gauge 2 (TG002_Old) Oldtg02 is a download from the first gauge submerged deployed at Casey in 1992. This gauge was lost but later recovered standing upright in the mud. The gauge overwrote its memory and stopped. The record runs from 02/04/97 to 08/09/99. It is highly probable that the position of the gauge was stable during this period. There is data from the same period from gauge TG06. Tide Gauge 2 (TG002) These folders contain data downloaded from the redeployed gauge TG02. TG02 was redeployed in November 2003. The Record runs from 12/11/03 to 4/3/05. It is expected that data will be downloaded from this gauge for the next 4-5 years. This gauge was deployed after the previously deployed gauge ran out of battery energy. There is therefore a substantial gap in the record prior to 12/11/03. Tide Gauge 6 (TG006) Tg06 was deployed at Casey in March 1996. The battery became exhausted in June 2003. The gauge was replaced by TG02 in Novenber 2003. There is therefore a gap in the data between June and November 2003. Tide Gauges 33, 34 and 36 (TG033, TG034, TGA001, TG036) ...
