Abstract
Odor emitted from rocky shore in seashore environment was estimated as an amenity factor, and compared with results in previous studies. Field surveys reveal that odor becomes weaker as the sea level rises, and slightly stronger as the illuminance increases especially at low tide, and that hedonic tone is improved at higher illuminance regardless of the sea level. Sensory evaluation of marine algae odor shows that the existence of seawater prohibits odor perception, and that of light contribute to higher pleasantness. These results seem to be related to the increase of the intertidal zone at low tide and the acceleration of biological activity by sunlight as previous studies pointed out. Consciousness research shows that much people recognize, accept, and require odor at rocky shore, and that odor intensity and acceptability affect on the formation of people's consciousness.
