Gravity survey was carried out in Cape Ryugu, and East and West Ongul Islands by the summer party of the 19th Japanese Antarctic Research Expedition (JARE-19) using a LaCoste and Romberg model G land gravity meter. Six gravity stations were established in Cape Ryugu on January 8, 1978. Gravity measurements at forty-six points in East Ongul Island were carried out at the end of January. The survey in West Ongul Island was made on February 6. Gravity data processing was made based on the International Gravity Standard Network (IGSN 71) and Japan Gravity Standard Network (JGSN 75).
