P045 SP IMPLEMENTATION IN DEEP-SEA SULPHIDES SEARCHES ALEXANDER A. PETROV Sevmorgeo State Company Rozenshteina Street 36 198095 St. Petersburg Russia Summary 1 The solution of a direct task for a spontaneous electrical field of deep-sea hydrothermal sulphide deposits is considered. The results of modeling demonstrate the opportunities of targets detection by any field components measurement. Two approaches to the decision of a reverse task are offered. In the first case the measured fields are approximated by set of fields of a small number of separate local objects. In the second variant the cell parameters of a regular mesh covering all
