My understanding of this process is that it mostly occurs near coastal upwellings which bring up nutrients from the deep and that it is responsible for a significant fraction of ocean carbon sequestration.

It's always worth remembering that the other end of the AMOC involves two main factors: (1) vorticity - mixing of heat from surface waters into the deep abyssal ocean (which decreases density causing the Atlantic Deep Water to start rising above the colder Antarctic Bottom Water) and (2) the wind - driven upwelling around the Antarctic Circumpolar Currdeep abyssal ocean (which decreases density causing the Atlantic Deep Water to start rising above the colder Antarctic Bottom Water) and (2) the wind - driven upwelling around the Antarctic Circumpolar CurrDeep Water to start rising above the colder Antarctic Bottom Water) and (2) the wind - driven upwelling around the Antarctic Circumpolar Current.

Consenquently, the associated SST pattern is slightly cooler in the deep convection upwelling regions of the Equitorial Pacific and the Indian Ocean, strongly cooler in the nearest deep convection source region of the South Atlantic near Africa and the Equator, warm over the bulk of the North Atlantic, strongly warmer where the gulf stream loses the largest portion of its heat near 50N 25W, and strongly cooler near 45N 45W, which turns out to be a back - eddy of the Gulf Stream with increased transport of cold water from the north whenever the Gulf Stream is running quickly.

For a rough estimate, downwelling water to the deep ocean in convection zones is about 40 Sv (10 ^ 6 m3 / s), assuming that comes in with say 2 deg C, and leaves (through upwelling, isopycnal and diapycnal diffusion), that is a heat flux of 320 TW, thus at least an order of magnitude larger than the geothermal fluxes.

Marine biological activity then transfers a bit more C to the deep ocean than cold, upwelling waters bring back up, such that the net sink to the deep ocean is about 1.6 GtC / yr, and much slower permanent removal in sediments.

The source of that CO2 is upwelling from the deep oceans — which is not a constant by any means.

Now the researchers noticed that all of these flu pandemics started in the boreal spring or summer and were preceded by La Niñas — the phases in the El Niño Southern Oscillation (ENSO) that see large upwelling of cold deep ocean water in the East Pacific, which is then spread out across much of the ocean.

The Antarctic ice sheet reached the coastline for the first time at ca. 33.6 Ma and became a driver of Antarctic circulation, which in turn affected global climate, causing increased latitudinal thermal gradients and a «spinning up» of the oceans that resulted in: (1) increased thermohaline circulation and erosional pulses of Northern Component Water and Antarctic Bottom Water; (2) increased deep - basin ventilation, which caused a decrease in oceanic residence time, a decrease in deep - ocean acidity, and a deepening of the calcite compensation depth (CCD); and (3) increased diatom diversity due to intensified upwelling.

This is nutrient rich water upwelling from the deep ocean in the Eastern Pacific.

In other areas, increased upwelling can lead to stimulated productivity, which can also lead to more organic carbon entering the deep ocean, where it is consumed, decreasing oxygen levels (medium confidence).

It may have its origin with the 800 year overturning of deep ocean waters from the polar sink places to the equatortial upwelling places.
