A Study on the Distribution of Net-Phytoplankton and Nutrients [N, P] of Xiangshan Bay in Summer

Abstract:

The distributions of net-phytoplankton and nutrients were studied in Xiangshan Bay in summer, 2012. The results showed that in summer, the higher values of net-phytoplankton cell abundance were distributed in the areas of Tie port, Huangdun port and Xihu Port. Whereas, the lower values were mainly found in the stations located in the outer area of Xiangshan Bay and the area around Liuheng Island. The content of nitrate in the middle of the bay was higher than that both in the bottom and the entrance of the bay. The concentration of nitrate in the bottom water was a little higher than that in the surface water. The distribution trends of the concentration of nitrite, ammonium and phosphate were almost the same. The higher values were discovered in the sea area of Tie port and Huangdun port and the lower were mainly distributed in the area of the outer Xiangshan Bay and the sea area around Liuheng Island. The distribution trends were almost the same no matter in the surface water or in the bottom water. From the bottom to the middle to the entrance of the bay, the values reduced in turn. In summer, in the water of Xiangshan Bay, net-phytoplankton cell abundance and nutrient (N, P) content didn’t have significant correlation. The concentration of the nutrients (Nitrate, Nitrite, Ammonium and Phosphate) was far more than the minimum threshold of the growth of phytoplankton.
