Title: Analysis of Driftwood Samples from Alaskan Villages

Driftwood has a major impact on residents of coastal Alaskan villages. In Savoonga, located on a tundra island in the Bering Sea, residents are turning to driftwood as a fuel source because of increasing oil prices. On the other hand, the village of Shaktoolik, on Norton Sound, is being battered by driftwood during increasingly common severe storms, which could likely destroy the village. Residents of these villages have many questions regarding the deposits of driftwood, including where it originates from and if it will continue to accumulate. We use time series analysis, common in dendrochronology, to analyze samples of driftwood cores collected over the last two years. We present our conclusions about the source(s) of the driftwood deposits and discuss the challenges of working with driftwood in dendrochronological studies.
