SPATIAL DISTRIBUTION OF NUTRIENTS IN BARGUZIN BAY, LAKE BAIKAL, RUSSIA
The nutrient dynamics of Barguzin Bay, Lake Baikal, Siberia, Russia, were analyzed in August 1997. Fourteen points were selected and located by a Global Positioning System (GPS). Distance from shore was categorized into three distinct groups: Group X, 0 to 10.00 km; Group Y, 10.01 km to 16.00 km; and Group Z, greater than 16 km. At each point, water quality samples were drawn from 0, 7.5, 15, 25, and 40 m depth. Nitrate, ammonium, and soluble reactive phosphorus concentrations were measured. The data was statistically analyzed using a two-way factorial Analysis of Variance (ANOVA). Inorganic nutrient concentrations measured in Barguzin Bay were very low. There were significant differences in nutrient concentrations between 0 to 10.00 km and greater than 16.00 km from shore (Groups X and Z), as well as from 10.01 to greater than 16 km (Groups Y and Z). The data revealed significant differences in mean nutrient concentrations among the various depths. There is no significance among the tests of the means by group at each individual depth. Nutrient concentrations were higher further away from potential inputs of the surrounding watershed, which could indicate that the wetland surrounding Barguzin Bay is an effective nutrient filter.
