From February 2003 to January 2004, a new superconducting gravimeter with a cryocooler was installed to replace the former device at the Syowa station in Antarctica. The new gravimeter has a high sensitivity of one nano-gal and is being used to survey the earth's core in the Global Geodynamics Project. A new type of diaphragm was confirmed to well isolate the vibration from the refrigerator cold-head and effectively prevent solid air contamination. A remote monitoring system from Japan is also going to be installed.
