The results of measurements made with a Tokyo Surface Ship Gravity-meter (a T.S.S.G.) aboard the R/V Hakuho Maru and measurements with a Graf-Askania sea gravimeter aboard the R/V Vityaz when both ships were cruising with the same heading and at the same speed were compared. The average difference between the results of measurements with the two gravity meters for 6 hours comparison was only 1.8 mgal.
