Absolute and relative gravity measurements were carried out at International Absolute Gravity Basement Network (IAGBN (A)) site #0417 at Syowa Station and at outcrops at Langhovde during the summer operation of the 53rd Japanese Antarctic Research Expedition (JARE-53). Two new gravity reference sites were established at Syowa Station and five at Langhovde. We present detailed data for the new sites, including location coordinates and gravity values.
