Abstract : The dynamic topography of the Pacific Ocean has been mapped for bimonthly periods relative to 500 and 1000 decibars and based on approximately 66,600 hydrographic stations. The maps indicate that the largest seasonal fluctuations are associated with the equatorial current systems. In the subtropical gyres and in higher latitudes, dynamic topography varies seasonally in accordance with the annual cycle of surface layer temperature, but the pattern of isobars does not change much between summer and winter. In the western portion of the North Pacific anticyclonic gyre, a U-shaped ridge is developed, separating the western boundary current from the interior of the gyre and linking the north equatorial ridge with a ridge at the right flank of the Kuroshio.
