A high-resolution sea surface temperature analysis product that blends in situ (ship and buoy) reports and satellite data and uses optimum interpolation to fill spatial gaps.
For the Global Ocean Data Analysis Project (GLODAP) extensive quality control and subsequent calibration were carried out for salinity, oxygen, nutrient, carbon dioxide, total alkalinity, pH and chlorofluorocarbon data. Data from approximately one million individual seawater samples were collected from almost 800 cruises carried during the years 1972-2013. The data were used to produce global climatology maps for many of the parameters.
World Ocean Atlas 2013 version 2 (WOA13 V2) is a set of objectively analyzed (1° grid) climatological fields of in situ temperature, salinity, dissolved oxygen, Apparent Oxygen Utilization (AOU), percent oxygen saturation, phosphate, silicate, and nitrate at standard depth levels for annual, seasonal, and monthly compositing periods for the World Ocean.
