ON THE ACCURACY OF MARINE GRAVITY MEASUREMENTS

Abstract:

We have assessed the accuracy of Lamont-Doherty Geological Observatory's global marine gravity data bank by examining the crossover errors (COEs) at intersecting ship tracks. >63 000 COEs were found, having a standard deviation of 22.43mGal (mGal = 10-5m s-2). We use the COEs to find and remove linear drifts and DC shifts present in the data set. This adjustment reduces the standard deviation to 13.96mGal. COEs generally decrease with latitude, which we attribute to undcertainties in the E...
