Distribution of temperature, salinity, SS, dissolved and particulate heavy metals(Cd, Co, Cu, Ni, Pb, Zn) were measured in the surface water of Marian Cove, King George Island, Antarctica, as part of environmental monitoring to the nearshore waters of adjacent to the King Sejong Station 2006.

Distribution of temperature, salinity, SS, dissolved and particulate heavy metals(Cd, Co, Cu, Ni, Pb, Zn) were measured in the surface water of Marian Cove, King George Island, Antarctica, as part of environmental monitoring to the nearshore waters of adjacent to the King Sejong Station 2006. Temperature ranged from -0.1 to 0.9((mean of 0.4±0.3℃) and showed low level in the waters around ice cliffs. Salinity ranged from 33.3 to 34.1(mean of 33.9±0.2psu) and spatial pattern was not as distinct as those of temperature. Concentration of SS ranged from 0.13 to 7.27(mean of 2.51±2.10㎎$ℓ^{-1}$) and the high values were found near ice cliffs which is significantly effected by terrigenous sediment of melt-waters. Concentrations of dissolved heavy metals such as Cd, Co, Cu, Ni, Pb, and Zn ranged from 0.074 to 0.087(mean of 0.079±0.003$\mu$g$ℓ^{-1}$), ranged from 0.005 to 0.337(mean of 0.031±0.077$\mu$g$ℓ^{-1}$), ranged from 0.160 to 0.695(mean of 0.314±0.141$\mu$g$ℓ^{-1}$), ranged from 0.335 to 0.447(mean of 0.377±0.024$\mu$g$ℓ^{-1}$), ranged from 0.012 to 0.073(mean of 0.037±0.017$\mu$g$ℓ^{-1}$), and ranged from 0.291 to 0.534(mean of 0.374±0.075 $\mu$g$ℓ^{-1}$), respectively. In case of particulate heavy metals, Cd, Co, Cu, Ni, Pb, and Zn ranged from 0.060 to 147.67(mean of 9.86±33.42$\mu$g$ℓ^{-1}$), ranged from 32.38 to 872.25(mean of 234.85±230.35 $\mu$g$ℓ^{-1}$), ranged from 23.39 to 1,431.39(mean of 400.51±408.19$\mu$g$ℓ^{-1}$), ranged from 27.06 to 138.42(mean of 59.19±30.23$\mu$g$ℓ^{-1}$), ranged from 34.76 to 1,743.90(mean of 454.03±505.18$\mu$g$ℓ^{-1}$), and ranged from 10.41 to 1,020.26(mean of 305.78±301.95 $\mu$g$ℓ^{-1}$), respectively. Distribution of heavy metal in austral summer 2006 also showed the notably elevated concentration in the waters around ice cliffs except Cd, and distributional patterns was similar to those of measured results annually. This result demonstrated that the spatial distribution of heavy metal in cove was significantly effected by inputs of melt-waters from ice cliffs. On the other hand, large amounts of melt-waters from continental slope on the central part of Barton peninsula have been introduced to cove were found and metal concentrations of input area were higher relatively in cove, indicated that this melt-waters were new input source of heavy metals in the Marian cove.
