title: Mesoscale Eddies in the Open Ocean: Review of Experimental Investigations
abstract: The paper is aimed at reviewing the studies of mesoscale eddies in the open ocean carried out by the Soviet and foreign institutions during the experiments in the specified geographical regions. The eddy-current effects are known since the 1930ies, and just the experiments "Polygon-67" in the Arabian Sea, "Polygon-70", MODE, POLYMODE, Tourbillon, "Mesopolygon" in the tropical Atlantic, "Megapolygon" in the northwestern Pacific Ocean have advanced our knowledge about physical nature of the ocean
