NODC Southern Ocean Atlas Observations and Analyses, by Gordon and Molinelli

Gordon (Columbia University), Molinelli (Science Applications Inc.), and Baker (Lamont-Doherty Geological Observatory) assembled the high-quality station data from the Southern Ocean found in the NODC archive. These individual stations (over 6000) are available (11 MBytes). The data were also interpolated to a uniform grid at 47 levels (14 MBytes). The variables include; temperature, salinity, sigma-t, silicate, oxygen, phosphate, and nitrate. Further information and contour maps are given in "Southern Ocean Atlas, published by the Columbia University Press".
