    • NODC Standard Product: International Ocean Atlas Volume 4 - Atlas of temperature / salinity frequency distributions (2 disc set) (NCEI Accession 0101473)

    Metadata Updated: December 2, 2025

    This Atlas presents more than 80,000 plots of the empirical frequency distributions of temperature and salinity for each 5-degree square area of the North Atlantic Ocean (80N to 30S) at all standard depth levels based on World Ocean Database 1998 data. Additional empirical statistical plots include the mean and standard deviation based on the arithmetic mean, the median and Median Absolute Deviation (MAD), winsorized estimates of the mean and standard deviation, quartiles, and skewness estimated from the quartiles. Some of these statistics are presented in both "normalized" and "natural" coordinates.

    Disc 1 contains seasonal distributions for the upper (0 m to 400 m) ocean. Disc 2 contains annual distributions for the deep (500 m - 5500 m) ocean.
