ABSOLUTE GRAVITY MEASUREMENTS AT SYOWA STATION : RESULTS BY THE ABSOLUTE GRAVIMETER WITH A ROTATING VACUUM PIPE
We measured absolute gravity values at Syowa Station, Antarctica, which is one of the subsets A of the International Absolute Gravity Basestation Network (IAGBN), from December 28,1992 to February 5,1993 by employing an absolute gravimeter with a rotating vacuum pipe (AGRVP) together with a transpor...
