Increases in the Pacific inflow to the Arctic from 1990 to 2015, and insights into seasonal trends and driving mechanisms from year-round Bering Strait mooring data

•The Bering Strait inflow to the Arctic increased from 2001 (∼0.7 Sv) to 2014 (∼1.2 Sv).•This is due to increasing far-field, pressure-head forcing, not local wind changes.•Concurrently heat and freshwater fluxes strongly increased (3–5 × 1020 J, 2300–3500 km3).•Seasonal data show winter freshening,...
