Abstract : 90% of the ocean floor lies beyond the reach of present marine gravimeters. For features with dimensions of the same order as the water depth, resolution demands an on-the-bottom profile. An inertial guidance component, the American Bosch Arma Lot D vibrating string accelerometer was adapted to measure gravity automatically in a free-fall, on-the-bottom vehicle. By special techniques, an accuracy in the range 1-2 mgal was obtained under preliminary operating conditions. (Author)
