How does this information affect actual global patterns of sea-surface temperature and salinity? Returning to the World Ocean Atlas 2018 (WOA 2018), Link 3A-1 provides information about ocean properties from the surface ocean to depths of 5500 m (3.4 mi.). Figure 3A-2 is a color-coded global ocean map of mean annual sea-surface temperatures (SSTS). This map is based on satellite, buoy, and ship measurements.

To understand more about vertical ocean properties, the WOA 2018 also has water property maps that can be created at a particular depth in the ocean. Figure 3A-4 is a color-coded global ocean map of mean annual temperatures at a depth of 2000 m. Temperature is measured in degrees Celsius at 0.5°C contours.
