Description Based on repeat observations made during 2001-2003 along two transects in the Taiwan Strait this study aims at understanding factors controlling primary productivity with an emphasis on biogeochemical cycling of nitrogen, the major bio-limiting macronutrient. The Taiwan Strait receives copious supplies of nutrients through river runoff and upwelling in its western and northeastern parts, respectively, but the phytoplankton biomass, as inferred from the Chl a concentration, does not appear to be commensurately high. It is proposed that high water turbidity results in light limitation of primary productivity, especially in the western part of the strait. The accumulation of nitrite in the surface mixed layer appears to be due to nitrate reduction during phytoplankton assimilation, whereas in the near-bottom waters nitrite is most likely produced during nitrification. The net balance between input and loss of nitrogen is inferred from the nitrogen tracer N. The Taiwan Strait is found to be a net recipient of combined nitrogen.
