E28S50 Sparker
描述
Spark is an artificial seismic source that employs a catamaran-style spark generator equipped with a cathode discharge device. It generates acoustic waves through instantaneous electrical discharge, enabling penetration through water columns and sub-seabed strata to support the detection of geological structures and resource distribution. With controllable energy output and high resolution, it is widely used in geophysical surveys in medium-to-shallow waters.
