Seth Flow Diagram
A schematic of the circulation over the Chukchi Sea and Beaufort/Chukchi slope is presented above, showing the three branches of the inflowing Pacific water. These branches are color-coded with navy blue being the most nutrient-rich waters and light blue being the least nutrient-rich. The Siberian Coastal Current (green) is present in summer and fall, but absent or weak in winter and spring. On the continental slope, the Pacific-origin water encounters Atlantic-origin Water (red) which is flowing counter-clockwise around the Arctic basin. Offshore of the slope, in the interior of the Canada Basin, is the clockwise wind-driven flow of the Beaufort Gyre (purple). Image courtesy Seth Danielson, UAF.
