Map of Ocean Circulation of Chukchi and Beaufort Seas

Schematic ocean current circulation of Chukchi and Beaufort Seas and geographic names. Sediments in this study formed a composite record from three core sites: HLY1302 MC29, GGC30 and JPC32 (69.97°N, 137.24°W, denoted by the (magenta circle) on the Mackenzie shelf in 60 m water depth. The green arrows denote the main pathway of Pacific-origin water exiting Chukchi Sea shelf and contributing to the Chukchi Slope Current to the west and Beaufort Shelfbreak Jet to the east. The blue arrow represents the Shelf Current in the vicinity of Mackenzie Canyon. The Beaufort Gyre (yellow arrow) situates in the Canada Basin. The bathymetry (in meters) is from The International Bathymetric Chart of the Arctic Ocean (IBCAO) v3 (Jakobsson et al. 2012).
