The basic principles of synergetics formulated in four laws are presen
ted in the review. The fundamental role of the critical phenomena theo
ry is emphasized in the study of self-organizing fluid motions. The av
ailable data on coherent structures in oceanic hydrophysical fields ar
e analyzed; the papers on synergetics methods for the ocean processes
study are reviewed. The methods for the description of phenomena cause
d by strong dissipative nonlinearity are shown to be promising.
