ON SOME PROSPECTIVE PROBLEMS OF THE OCEAN FLUID-DYNAMICS

Three interconnected prospective problems of the ocean fluid dynamics are considered: the oscillations of the World ocean general circulatio n and the climate (''synergetic'' oscillations with multimonthly perio ds in the system ''large-scale flows - synoptic eddies'', the oscillat ions with rotation periods of the giant anticyclonic gyres and oscilla tions of the World ocean ''conveyor belt'' thermohaline circulation wi th periods of decades and hundreds of years); subsynoptic eddies and o ther coherent mesostructures; and, finally, mesostructures in the form of convective plumes above bottom geysers - the so called ''black smo kers''. The prospects of studies of these problems and necessary new m ethodology and equipment are discussed.
