A project, to explore the sea environments of subtropical Okinawa, Japan, has been running with financial aid from the Education Agency of Japan. Surveys may reveal the characteristics of the currents around coral reefs and deep-sea water up-welling,

Land Hermit Crabs(LHC) usually live among vegetation on land adjacent to coasts. At spawning time they make their way to the sea where they release their spawn. Due to ever increasing construction of artificial barriers between land and sea, LHC's an

A new theory is proposed in this paper explaining the generating of upwellings in ocean currents near the shore and in rivers. Up until now, there have been the bursting phenomenon theory and the cork-boil Eddies theory about upwellings. The proposed

Wave damping effects of reef sea bed with group of reef blocks are investigated. In the first, a field survey was carried out at the coast of Ikei Island to glasp natural condition of reef sea bed, and also to make clear characteristics of reef block

The Okinawa Islands are frequently hit by typhoons. There are many more sea salt particles in summer typhoon winds than in the winds that blow during other seasons. Disasters caused by these salty winds occur much more often in the Okinawa prefecture

As well as the alignment of breakwaters which contribute to calmness of harbour regions, the plane distribution of total wave pressures to breakwaters is also important in design of reakwaters. In the planning of the New Naha Port, the wave shelterin

This paper presents the study on wave damping action at the barrier reef. The theoretical model takes account of the resisting effects on wave motions, which are shown as linear terms, while the non-linear ones such as the effects of vortex and wave

In this paper, the authors propose the importance of estimation of mean sea water level and wave run-up from wave traces for the development of an area along the coast, and incidentally, thouch on the process which hit upon this new study. Main concl
