Abstract: Aiming at the Simrad deep-tow system and the deep-tow system co-developed by Shanghai Jiaotong University and DOE Company of USA,the software which calculates the polymotallic nodule's coverage,grain size and abundance from deep-tow's optic image is developed independently.The methods of the geometrical revision of the deep-tow altitude and the calculation of the grain size are put forward,The correlation of the nodule's abundance with coverage and grain size of the Pacific China's polymetallic nodule in the east area and the west area is analysed,and the mathematic pattern to calculate the polymetallic nodule's abundance from the deep-tow system's optic image is established.
