衛星リモートセンシングによる長崎港の水質状況調査

抄録

There are so much reclamation ares in Nagasaki city. Now, a new reclamation work of the foreshore on Nagaski harbour is being planed consideration. Because of this plan, there is a strong suspention that the natural purification of sea water pollution in this area.
In this paper, a change with passage of time from 1984 to 1991 of the sea water transparancy on Nagasaki harbour was checked by remote sensing technique using LANDSAT-TM satellite data. And a new active remote sensing technique was tested by digital camera in combination with conventional remote sensing techniques.
As a result of this research, a secular change of transparancy in Nagasaki harbour have not appeared from 1984 to 1991. And It is clear that the new active technique by digital camera will become a useful technique.
