Abstract : In planning enclosed areas in the ocean, such as offshore harbors for fishing or recreational boats, one has to consider very carefully the problem of forced seiches due to surface water waves. A number of papers have been written on this problem, but to the authors' knowledge, only one of them has treated the case of an artificial bottomless circular harbor in the open ocean, for which the walls extend only part way to the sea floor. C.J.R. Garrett (1970) made a theoretical study of the excitation of waves inside such a harbor for the 'no-entrance' case. The object of this paper is to evaluate experimentally the behavior of the sea surface inside such a harbor, to compare the results with the theoretical values obtained by Garrett, and to extend the observations to the case for which there is an entrance to the harbor.
