Key Laboratory of Marine Geology and Environment, Institute of Oceanology, the Chinese Academy of Sciences, Qingdao , China, 2. University of the Chinese Academy of Sciences, Beijing , China) Received: Nov. 17, 2016 Key words: marine gravimetry; KSS32-M marine gravimeter; damping delay time; KSS31-M marine gravimeter; Oetworth Abstract: Based on the data measured using the KSS32-M ocean gravimeter in recent years, the measurement stability and data reliability of this instrument are analyzed; moreover, the methods employed to measure the intersection point difference, repeating survey line, and coincidence line using the gravimeter are compared. The delay time of the gravimeter is 70 s, calculated using the maneuver steering method. Based on this calculation, the accuracy of gravimetric measurement is found to be 0.65 mgal. According to the gravity profile collected by the gravimeter, the correlations of the coincidence lines are highly correlated. The absolute value of the intersecting point difference of four coincident surveying lines is 1.66 mgal, and the precision is 0.59 mgal. All data meet the national standard of the intersection which the gravity measurement network of the national standard of the intersection point difference that less than 2 mgal. The average value of the anomalies of the matching points is less than 0.9, the variance is less than 0.8, and the correlation is higher than In summary, this study shows that the data measured by the KSS32-M gravimeter are stable and reliable.
