The shortness of gaged river flows limits our understanding of the variability of the river component of heat and fresh water inflow to the Arctic Ocean. This talk describes a tree-ring approach to addressing the uncertainty of Arctic river flows using a combination of non-riparian and riparian trees growing in the floodplain of the lower Ob River, in western Siberia. The talk focuses specifically on the tree-ring signal for inter-annual variability of flooding, which happens on a massive spatial scale each year along the Ob with spring ice break.
