In July 2000 the diurnal cycle of analyses was conducted in order to determine variation in the concentrations of nitrogen and calcium compounds as well as dissolved gases in surface microlayers of a shallow coastal barrier lake located at the Baltic Sea coast. Water for analyses was collected in a diurnal cycle for the period of 24 h from lake Dołgie Wielkie. The analyses were conducted on the surface microlayer with a thickness of approx. 100 μm, a layer with a thickness of approx. 250 6m and a layer of subsurface water from a depth of 15 cm. Based on the analyzed data, information was collected on the migration of nitrogen compounds between the analyzed layers. Changes were observed in nitrogen forms reduced to oxidized forms and vice versa.
