| Research Abstract |
We obtained the data of phytoplankton photosynthesis and iron in the Oyashio region of the NW Pacific during the spring blooms. Coastal Oyashio waters, which contained relatively high amount of iron, stimulated the photosynthetic activity of phytoplankton, especially diatoms. However, diatoms were generally stressed by low iron availability even in the spring blooms. We also determined the effects of temperature, light, and iron availability on photosynthetic features of the representative bloom-forming diatom species isolated from Oyashio waters, through batch culture experiments.
