Time series of volume transport below isotherm θ = 1.2 °C across the mooring transect (blue lines), dissolved oxygen at depth 3597 m of M1 (purple lines), and depth of the isotherm θ = 1.2 °C (pink lines). The thin lines represent daily series, thick lines are 24-day Butterworth lowpass filtered series. Light blue background indicates the period with eastward transport. Unshaded background indicates the period with westward transport. The positive (negative) value of transport stands for eastward (westward) transport. Source data are provided with this paper.
