This study presents hydro chemical characteristics of surface waters of the South Bay, Antarctic Peninsula, between the coordinates 62°40′S and 60°28′W. The surface water samples were collected from different stations. Water Depth, salinity, temperature and Secchi Disk Depth measurements were carried out on board of a Zodiac Boat from 05.02.2018 to 19.02.2018. A total of 20 surface water samples were handled by PVC and analyzed for major ions, pH and conductivity. Secchi disk depth, surface water temperatures and water depth values ranged from 1.0 to 4.0 m, 19.1 to 118.5 m and 0.10 to 2.50 oC, respectively. These parameters were mutually comparable with each other, denoting close relationship with suspension. Salinity and conductivity were found to covary, suggesting influence of salt content of on the conductivity. Cl /Na ratio varied from 1.5 to 1.6, being lower than that of 1.8. There was a strong relationship between Cl/Na (r=0.74), reflecting the effect of freshwater input on aforementioned ratio. Na, Mg and K showed strong correlation coefficient (r>0.99). However, Ca exhibited lower correlation coefficients with remaining cations. It might be suggested that Na, Mg and K were conservative cations whilst Ca concentrations were partially affected by processes such as uptake by phytoplankton. Ion balance were predominated by cations, exhibiting missing anion bicarbonate. As a result, these values hopefully reflected some important clues for temporarily and spatially environmental effects onto the partly icy surface water which should be monitored further in detail to get better understanding of its dynamics in the South Bay.
