Building a model of the Earth's gravitational field within the Caribbean Sea based on satellite altimetry data

Abstract
Methods for processing measurement information collected over the past 30 years by altimetry spacecraft with various measurement technologies and orbit characteristics are systematized and described. The description and classification of measurement information files is given. Based on the removal-recovery method, a software package for determining the characteristics of the gravitational field and the figure of the Earth by satellite altimetry has been developed. On the example of a geologically complex and seismically active region (the Caribbean Sea), a model of the gravity field (gravity anomalies) was constructed and its accuracy characteristics were evaluated. The calculated standard deviation of gravity anomalies from the data of the EGM2008 global model does not exceed 4 mGal in the open sea and 14 mGal in the coastal zone, which corresponds to the international level. At the moment, a digital interactive gravity model of the Global Ocean is used to solve applied problems of geophysics and geology, in particular, to forecast oil and gas fields.
