A new gridded ocean climatology, the Polar science center Hydrographic Climatology (PHC) has been created that merges the 1998 version of the World Ocean Atlas (Antonov et al., 1998; Boyer et al., 1998) with the regional Arctic Ocean Atlas (EWG, 1997; 1998). The result is a global climatology for temperature and salinity that contains a good description of the Arctic Ocean and its environs. Monthly, seasonal, and annual average products have been generated.
