“…Figure 2 shows the Pacific meridional overturning stream function in each simulation. All simulations capture the basic structure of the Pacific THC: the deep northward inflow of Circumpolar Deep Water from the Southern Ocean, and the middepth southward return flow with less upwelling to the surface 18,20 . As for the horizontal pattern of the Pacific deep circulation, observations suggest that water separating from the Antarctic Circumpolar Current enters the Pacific Ocean through the Samoan Passage and flows northward along with the bottom western boundary currents 21 .…”

Vertical mixing in the ocean is a key driver of the global ocean thermohaline circulation, one of the most important factors controlling past and future climate change. Prior observational and theoretical studies have focused on intense tidal mixing near the sea bottom (near-field mixing). However, ocean general circulation models that employ a parameterization of nearfield mixing significantly underestimate the strength of the Pacific thermohaline circulation. Here we demonstrate that tidally induced mixing away from the sea bottom (far-field mixing) is essential in controlling the Pacific thermohaline circulation. Via the addition of far-field mixing to a widely used tidal parameterization, we successfully simulate the Pacific thermohaline circulation. We also propose that far-field mixing is indispensable for explaining the presence of the world ocean's oldest water in the eastern North Pacific Ocean. Our findings suggest that far-field mixing controls ventilation of the deep Pacific Ocean, a process important for ocean carbon and biogeochemical cycles.

“…Since the Bølling-Allerød period, ocean circulation in the North Pacific has been in an interglacial mode, essentially the same as the present one. The present abyssal circulation from the south flows into the North Pacific, and upwells to mid-depth and returns south as the Pacific Deep Water (PDW) (Schmitz, 1996). Above the PDW, the NPIW with a salinity minimum lies at depths of 300 to 800 m (Talley, 1993).…”

Ventilation changes in the western North Pacific since the last glacial period

Abstract.We reconstructed the ventilation record of deep water at 2100 m depth in the mid-latitude western North Pacific over the past 25 kyr from radiocarbon measurements of coexisting planktic and benthic foraminiferal shells in sediment with a high sedimentation rate. The 14 C data on fragile and robust planktic foraminiferal shells were concordant with each other, ensuring high quality of the reconstructed ventilation record. The radiocarbon activity changes were consistent with the atmospheric record, suggesting that no massive mixing of old carbon from the abyssal reservoir occurred throughout the glacial to deglacial periods.
