3 Temperature range and geographical sectors

 The sea areas subject to these temperatures vary greatly throughout the year and do not always uniformly follow specified latitudes. Table 2 illustrates the approximate variation of water temperature with latitude during the coldest months of the year in the northern and southern hemispheres. More exact information on seawater temperature can be found at www.nodc.noaa.gov/dsdt/oisst/index.html or appropriate local sources.
