Abstract:

Primary production in water column (P_p) varied from 107 to 312 mg C/m**2/day in Yenisey Bay: from 25 to 63 mg C/m**2/day in Obskaya Guba: and from 20 to 359 mg C/m**2/day in the open sea, that is: in the western Kara Sea and Ob-Yenisey shoals. The average concentration of chlorophyll a in the photosynthesis layer (C_ph) ranged from 0.2 to 1.8 mg/m**3 in these two regions, lower than in the estuaries of Ob (1.6-21.7 mg/m**3) and Yenisey (2.0-5.2 mg/m**3) Rivers. An inverse relation between surface salinity (S) and chlorophyll concentration (C_s) and chlorophyll concentration in the photosynthesis layer was found for all of the regions. The highest values of C_s and C_ph (0.8-22 mg/m**3) were measured at S<10 ppt, and the lowest values (0.2-0.8 mg/m**3) at S>22 ppt. A similar correlation of S with values of Pp occurred only in the Yenisey Bay and offshore regions. Obtained results agree well with the "outwelling" hypothesis. It states that large part of organic matter produced in estuaries is not used in estuarine trophic chains but is transported into adjacent sea areas and increases their productivity. Low values of Pp in the study regions may be attributed to such unfavorable factors as deficiency in nutrients, low temperature and turbidity, and lack of solar radiation.
