Ocean currents in the Pacific Ocean. Satellite-based graphic showing ocean currents (swirling coloured lines) on an Earth globe centred on the Pacific Ocean. The colours indicate ocean temperatures, ranging from the warm tropics (red) to cooler water (green) in more temperate latitudes. The major currents are the Pacific's North Equatorial and South Equatorial, separated by the Pacific's Equatorial Counter. The dusk terminator (day-night line) is at lower right, marking the places from where the Sun is seen setting in the west as the Earth rotates on its axis.
