| Summary: | (basaltic) mineral phase at some locations and/or diagenetic 1 00 cm), with a few exceptions. There was also no Ag, Cd, and Hg there was poor correlation with Fe, likely and Zn. To make comparisons between locations easier, the compared to the Kara and Pechora Seas, suggesting different concentration of all elements was normalized to Fe to account concentrations of these elements. Copper, Ni and Zn showed differences were found between metal to Fe ratios at the Fe ratios of the East Siberian and Laptev Seas. There was, For the work described in this thesis, a total of 218 samples for variability in grain size and mineralogy. For the metals from 104 cores from the East Siberian, Laptev, Kara, and good correlation with Fe, suggesting these elements are from however, a significant difference when these two seas were metal concentration to sediment from its likely source, the mineralogy in the drainage basins of eastern and western natural inputs to the sediments. Arsenic, Ba, Cr, Pb, and Sb Ob and Yenisei rivers. partially due to analytical variations caused by the low Pechora Seas and the Ob and Yenisei Rivers were analyzed for redistribution of these metals. No statistically significant showed variable correlations, suggesting a more mafic Siberia. Sediment from the Kara Sea was similar in trace statistically significant difference in the average metal to surface (0-2.5 cm) of the sediment cores and the bottoms (5- the trace metals Ag, As, Ba, Cd, Cr, Cu, Fe, Hg, Ni, Pb, Sb, |
