Abstract
Natural environments and marine organisms in the artificial lagoons atthe Tannowa-Hakozukuri Coast facing Osaka Bay are investigated. At first, changes of meteorological and oceanographic conditions and water quality were measured. And, also the habitable conditions of marine organisms in two tide pools were observed in the case of one opening and two ones. Consequently, the characteristics of vertical and horizontal distributions of marine organisms were made clear in these tide pools. Moreover, the marine organisms in the pools were compared with those in concrete-made detached breakwater.
