The Influence of Season to Nitrate and Phosphate Content Eutrophication in Banda Sea

Observation on phosphate and nitrate nutrient content were carried out in May, August, November, 1996 and February 1997 in Banda Sea. The results showed the averages content of phosphate and nitrate in August is higher compared to May, November and February. Phosphate content in August 1.492 μg.at/l, while in May, November and February are 1.025 μg.at/l, 0.878 μg.at/l and 0.766 μg.at/l. Nitrate content in August is 1.932 μg.at/l, while in May, November and February are 0.975 μg.at/l, 0.804 μg.at/l and 0.670 μg.at/l respectively. This result fixed with statistical Analysis (Randomized Block Anova) (Fh > F t 1%). This condition is caused by upwelling process in Banda Sea at that time
