P(論文) A gravimetric connection from Tokyo (Japan) to McMurdo Sound (Antarctica) via Sydney (Australia) and Christchurch (New Zealand) was carried out by means of two LaCoste & Romberg gravimeters in October 1980 as part of international gravimetric connections around the Circum-Pacific zone. The gravimetric connection between Tokyo and McMurdo Sound could not be performed so precisely because scale values of the gravimeters employed could not be accurately determined. The gravity measurements in McMurdo Sound, however, were precisely performed using the two gravimeters in spite of low ambient temperatures. It was ascertained that the International Gravity Standardization Net 1971 (IGSN 71) is a homogeneous network inclusive of the gravity stations in McMurdo Sound. departmental bulletin paper
