The article presents research concerning sea ice drift routes in the Arctic Ocean and the lack of uniformity in the sea ice record of the last 10,000 years. Scientists used radiocarbon dating to determine the age of driftwood samples from Asia and American and beach ridge complexes on the coast of northern Greenland to measure the extent of ice during periods including the Holocene Thermal Maximum (HTM) and the Medieval Warm Period. They determined that the periods of low sea ice accumulation in that area corresponded with periods of higher ice in the western parts of Ellesmere Island, Nunavut. This pattern indicates that there may be cycles in currents such as the Beaufort Gyre (BG), Transpolar Drift (TPD), and the Arctic Oscillation.
