Nitrogen Uptake Rates during Spring in the NE Arabian Sea

Figure 2

Vertical profiles of nitrate, Chl a, measured total N uptake rates (sum of 𝜌NO₃, 𝜌NH₄, and 𝜌urea), and Trichodesmium abundance. The shaded area represents the mixed layer. (a) refers to coastal stations 2, 4, 14, and 15 (water depth <200 m) and (b) open ocean stations 5, 8, 10, and 12 (water depth >200 m). Error bars represent the 1-sigma (standard deviation) in the measured N uptake rates.
