    Abstract
  • Investigations of the size-fractionated chlorophyll a and primary productivity were carried out in the western Arctic Ocean during the 3nd national arctic research expedition of China during the summer of 2008. The results show that the surface chlorophyll a concentrations are 0.013 19.367 μg/dm3 and the average value is (0.677±2.2661)μg/dm3 in the surveyed area. Chlorophyll a concentrations in the subsurface water are higher than these at the surface layer and in the deep depth water. The distribution of chlorophyll a is obviously areal characteristics, the areal arrange order of the water-column chlorophyll a is the Chukchi shelf, the Beaufout Sea, the Chukchi Plateau, the Mendeleev Ride and the Canada Basin. The chlorophyll a concentrations decrease in two sequential samplings on Section R, with water-column average values of (3.083±3.009) and (0.797±0.774)g/dm3, respectively. The primary productivity at the surveyed stations is 0.050 2.453 mg/(μm3·h). The primary productivity of the Chukchi shelf is higher than that of the Chukchi Plateau,the Canada Basin,the Beaufout Sea and the Mendeleev Ride.The results of the size-fractionated chlorophyll a and primary productivity show that microplankton accounts for the majority of the total chlorophyll a (51.75%) and primary productivity(50.89%) on the Chukchi shelf and the Beaufout sea Shelf. The contributions of the picoplankton account for the majority of the total chlorophyll a (68.25%) and primary productivity (56.13%) in the Beaufout Sea,on the Chukchi Plateau, the Mendeleev Ride and in the Canada Basin.
