Figure 3From: Distributions of inorganic nitrogen and biological production in the equatorial Pacific: a basin-scale model sensitivity study of nitrification Profiles of (a) and (b) nitrate, and (c) and (d) ammonium at 0° (left panel) and 3°S (right panel) along 180° during October-November, 1996. Symbols denote data [8]. Lines represent model simulation for the standard (black), NITR1 (red), NITR2 (green) and NITR3 (blue). Dashed lines indicate the euphotic depth.Back to article page
