This atlas contains maps of phosphate, nitrate and silicate at selected standard levels of the world ocean in a one-degree grid. The fields used to generate these maps were computed by objective historical data. Maps for all-data annual composing periods are presented. Data distribution maps are presented for various composting periods. Basin zonal averages and basin volume averages are computed form these objectively analyzed fields and presented in the form of figures and tables.

The field of oceanographic data assimilation is now well established. The main area of concern of oceanographic data assimilation is the necessity for systematic model improvement and ocean state estimation. In this respect, the book presents the newest, innovative applications combining the most sophisticated assimilation methods with the most complex ocean circulation models.Ocean prediction has also now emerged as an important area in itself. The book contains reviews of scientific oceanographic issues covering different time and space scales. The application of data assimilation methods can provide significant advances in the understanding of this subject. Also included are the first, recent developments in the forecasting of oceanic flows.Only original articles that have undergone full peer review are presented, to ensure the highest scientific quality. This work provides an excellent coverage of state-of-the-art oceanographic data assimilation.
