Gravimetric Survey

 

the set of measurements of the quantities characterizing the gravitational field of a particular region. It also includes the determination of the positions of gravimetric points. A gravimetric survey is conducted using gravimeters, pendulum instruments, and torsion balances.

Depending on their purpose, gravimetric surveys are subdivided into general and detailed types. A general gravimetric survey is used in studying the figure of the earth and the general geological structure of large regions; a detailed survey is used to determine individual geological structures, ore bodies, and deflections of the vertical. Depending on the nature of the distribution of the points, gravimetric surveys are divided into area and profile types (the latter is a survey of points lying along a line). Gravimetric maps, which portray the anomalous part of the earth’s gravitational field, are constructed on the basis of the data from gravimetric surveys.

There was no need to apply such a low-pass filter to the 2017 marine data (consisting of 3450 points) since the sole purpose of the shipborne campaign was gravimetric survey (lasted 72 h with vessel's velocity of 8-9 knots).
Gravimetric Survey on the Bench Marks of the Levelling Line
In spring 2007, we performed a relative gravimetric survey to determine gravitational acceleration in 45 bench marks of the levelling line.

Data Processing and Accuracy Estimate of the Gravimetric Survey
In processing data obtained during the relative gravimetric survey, we considered the influence of air pressure, the movement of Poles and short-time gravimeter drift influence.
