Observation and Data Archiving System of a Superconducting Gravimeter at Syowa Station, Antarctica

摘要: A superconducting gravimeter (SG, model TT70#016, GWR Instruments) was deployed for the first time in Antarctica 1992 at Syowa Station. Observations began April 1993. Although SG equipped with a 10 K cryocooler, its liquid helium (LHe) required refilling twice year to maintain state. The LHe produced by separate liquefier. After continuous gravity measurement 11 years, it replaced second (CT#043) 4 cryocooler December 2003 order reduce loads of person charge production. Because manufacturer could not supply replacement this ceased November 2009. In January 2010, new (OSG#058) installed and had recorded high-quality series data acquired every more than five years without interruption. personal computer (PC) controlling observation acquisition is connected PCs Japan through an Intelsat satellite communication link, we can check status observations real time. It also possible fix remotely certain problems gravimeter. observed are transferred daily server Japan. Also included upload diagnostic such as temperature coldhead environmental atmospheric pressure. Plots publicly available. raw 1 s sampling interval released registered researchers. along greatly useful investigating solid earth dynamics especially long period bands. We provide necessary information use these long-range sets.
