には利用されていない現状である。 Manganese nodules are seen as a promising mineral resource for the next era. However, because it exists deep under the sea, it is difficult to explore and mine it. especially,
Regarding exploration methods, the recent development of deep-sea TVs has made it easier to observe the distribution of nodules.However, it is not possible to measure the manganese content in nodules at the site on the deep sea floor, so samples must be taken up to the ship. There was no other way but to measure it. There was a huge waste of time and effort in transporting the sampler back and forth to a depth of approximately 5,000 meters to retrieve the sample. On the other hand, recently, using the activation analysis method, at the same time as observing on TV,
A method for analyzing the dignity of baby boomers has been proposed. First, the surface of the nodule on the ocean floor is radioactive using a radioactivity irradiator. Next, a measuring instrument is moved onto the nodule, and the amount of each radioactive element contained is detected, and the results are communicated via a cable on the ship. However, this proposed method requires a radiation source, which makes the device large and complex, making it unsuitable for use on the ocean floor.In addition, the use of radiation is prohibited in Japan for safety reasons. Therefore, it is currently not actually used.

It has been found that the manganese content of nodules can be determined very easily. This method uses significantly simpler and more economical equipment than the activation analysis method, and is also superior in safety. Furthermore, according to this method, the manganese content can be easily measured in a short time, so it can be operated effectively even under adverse conditions on the deep sea floor.

(5 types containing 0, 10, 20, 30, and 50% MnO 2 ) and collected seabed manganese nodules (2 types containing 17 and 25% MnO 2 ). As shown,
At wavelengths above 550 mμ, the albedo value increases as the manganese content of the sample decreases, and shows a value proportional to the manganese content. The curve shown by the thick solid line is that of the submarine manganese nodule. In particular, 700
In the wavelength range ~740 mμ, it is noticeable that the albedo values vary proportionally due to the difference in manganese content.
