Trichodesmium spp. is probably the most important diazotroph in oligotrophic tropical and subtropical seas. Their N fixation relieves the restraining of N limitation to the marine primary production, and promotes the absorption of CO 2 . Therefore, their distribution and N fixation are paid more attention on the condition of global warming in recent years. We summarize the studies on Trichodesmium...
The distribution and size fractions of chlorophyll a (Chl a) concentration in the eastern equatorial Pacific Ocean in boreal autumn were investigated during October and November, 2011. Environmental factors, including hydrology and nutrients, that might affect the distribution and size composition were analyzed. A total of 18 stations including 11 CTD stations and 7 navigation stations were selected...
