Abstract
Close to the sea surface, the waters of the ocean are mixed by wave action so that their temperature and chemical properties are almost uniform vertically. Within this mixed layer, which varies in depth from a few meters to several hundred meters, a single measurement of a chemical property is likely to represent that property throughout the layer. Because the water below is colder or saltier and therefore denser, the layer is stable enough to persist for weeks, months, or even years.
