Abstract

In February 2003 to January 2004, a new superconducting gravimeter with a cryocooler was installed to replace the former one in Syowa Station on the Antarctica. It has a high sensitivity of one nano-Gal to survey inside the earth in the Global Geodynamics Project (GGP network). A new type of diaphragm was confirmed to well isolate the vibration from refrigerator cold-head and to prevent the solid air contamination perfectly. Real time remote monitoring system from Japan is also established.
