Title: Eddies in the Oyashio current

Description: The photograph from NASA shows eddies in the Oyashio Current, off the Kamchatka Peninsula in the Bering Sea, in March, 1992. The current, part of the the western boundary current of the North Pacific subpolar gyre, is baroclinically unstable and sea-ice provides flow visualization. Snow cover (white) covers the thicker ice flows just to the right of the centre of the image.
