NODC Standard Product: World Ocean Atlas 1998 (7 disc set) (NCEI Accession 0095184)

browse graphicPreview graphic
The World Ocean Atlas 1998 (WOA98 and WOA98F) consists of 7 CD-ROMs: 3 discs contain 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 and 4 discs contain Figures.

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 (WOA98) 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.

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. The images are on the discs as shown below:

WOA98F-01 Temperature
WOA98F-02 Salinity
WOA98F-03 Oxygen
WOA98F-04 Nutrients and Chlorophyll

Each CD-ROM contains an HTML front-end for easy searching of the images with an Internet browser.

Supplemental Information
The contents of these discs are available as complete ISO 9660 disc images, from which an identical replica of the original discs may be burned on new CD/DVD media, by navigating to the .iso files in the data/0-data/disc_images/ subdirectory.

Disc images 0095148_disc_image_1.iso, 0095148_disc_image_2.iso and 0095148_disc_image_3.iso are the disc images of the three WOA98 discs;
Disc images 0095148_disc_image_4.iso through 0095148_disc_image_7.iso are the disc images of the four WOA98F (figures) discs.
Purpose This dataset is available to the public for a wide variety of uses including scientific research and analysis.
