Coastal regions represent the “third sector of the earth” which is neither land nor sea, but a peculiar mix of the two. There is no accurate technical description for this sector.
Studies of salt damage, as an environmental problem of coastal regions, have been conducted for a considerable time. As previously reported, a field measurement of seawater and meteorological information, coastal forms, and the distribution of aerial sea-salt particles near the coast of the Kitakyushu area (within 100m of the coastline) was conducted to obtain fundamental data for comprehensive, wide-area planning of the development of the coastal region from an environmental point of view. A field measurement was also conducted of the area within a distance of 2, 000 m from the coastline.
This paper presents an outline of the field measurement methods employed in surveying distribution of aerial sea-salt particles, and explains the results of measurement and analysis.
