Description
The World Ocean Atlas 1998 (WOA98) consists of 3 CD-ROMs containing objectively analyzed fields of temperature, salinity, dissolved oxygen, derived oxygen variables (Apparent Oxygen Utilization and oxygen saturation), nutrients (phosphate, nitrate, silicate) and chlorophyll along with fields of various statistics. The World Ocean Database 1998 (WOD98) 5 disc CD-ROM set contains observed and standard level flagged data used to generate the WOA98 fields. more

The data on each WOA98 CD-ROM consists of statistics of observed (vertically interpolated) data (unanalyzed) for one-degree squares and five-degree squares at standard depth levels. The following statistics for each grid square are included: 1) number of observations, 2) mean, 3) standard deviation, 4)standard error of the mean. The objectively analyzed fields and associated statistics for temperature, salinity, oxygen, nutrients, and chlorophyll are on three CD-ROMs as shown below: WOA98-01 annual, seasonal, monthly fields for temperature and salinity, WOA98-02 annual, seasonal, monthly fields for oxygen and the derived variables Apparent Oxygen Utilization and % oxygen saturation WOA98-03 annual and seasonal fields for phosphate, nitrate, silicate, and chlorophyll There are four types of directories within each CD-ROM: masks, programs, utils, and variable data directories (variable data directories are identified by the variable name, e.g. temperature, salinity, etc..). README files are available on each CD-ROM in HTML, Word Perfect 8, and text formats. World Ocean Atlas 1998 Figures (4 discs) The World Ocean Atlas 1998 Figures (WOA98F) CD-ROM set consists of gif images of objectively analyzed fields of temperature, salinity, dissolved oxygen, derived oxygen variables (Apparent Oxygen Utilization (AOU) and oxygen saturation), nutrients (phosphate, nitrate, and silicate) and chlorophyll along with figures of various statistics for these variables. Each CD-ROM contains an HTML front-end for easy searching of the images with an Internet browser.
