Abstract
CHLORIDE ION IN PORE WATERS FROM BOTTOM SEDIMENTS OF PUCK BAY
Summary
The subject of the paper is the spatial distribution of chloric ion in pore water from the Puck Bay (western part of the Gdańsk Bay). The subject of investigation was assumption pore water to 110 cm depth which was analysed in 5 cm intervals. Concentration of chloric ion in this water was between 0.37 and 4.24 g/dm3. The overall pattern in the vertical distribution of chloride is its descrease with depth. The distribution of chloride in pore water was produced as gradient ΔCl/dm3/cm. On the basis of this parameter there have been separated three regions of the bay bottom: I - ΔCl < 0.01; Il - 0.01 < ΔCI < 0.05 and III - ΔCl > 0.05. In regions Il and III there appears freshing pore water of oligochloric and chloric normal type. The generally low concentration of chloride in pore water is conditioned by the bay genesis. The spatial differentiation of gradient within the bottom, is according to the authors, connected with the existenca of fresh ground water under the bay bottom, which might be the zone of their drainage.
