PENGARUH MUSIM TERHADAP FLUKTUASI KADAR FOSFAT DAN NITRAT DI LAUT BANDA

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 g.at/l, while in May, November and February are 1.025 g.at/l, 0.878g.at/l and 0.766 g.at/l. Nitrate content in August is 1.932 g.at/l, while in May, November and February are 0.975g.at/l, 0.804 g.at/l and 0.670 g.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.Keywords: Banda sea, phosphate, nitrate, upwellin
