Short summary
Based on mineral records from the northern Chukchi Sea, we report a long-term decline in the Beaufort Gyre (BG) strength during the Holocene, consistent with a decrease in summer insolation. Multi-centennial variability in BG circulation is consistent with fluctuations in solar irradiance. The Bering Strait inflow shows intensification during the middle Holocene, associated with sea-ice retreat and an increase in marine production in the Chukchi Sea, which is attributed to a weaker Aleutian Low.
