In places surface water sinks —
driving deep ocean currents — and in others it upwells.

Antarctica's strong Circumpolar
Deep Current circles the entire continent,
driven by strong winds called westerlies, which also create the Southern
Ocean's dangerous and choppy waters.
Thermohaline circulation, also known as the
ocean's conveyor belt, refers to the
deep ocean density -
driven ocean basin
currents.
Its measurements of
ocean saltiness will also help scientists understand how changes in salinity affect the
deep currents that
drive ocean circulation.
Richard Thomson, a physical oceanographer at the Institute of
Ocean Sciences in British Columbia who also did not take part in the work, says that
deep - sea
currents could be the
driving factor behind the extreme variations in biology.
It's what
drives the atmospheric circulation and the
ocean currents that mix the upper warm layers of the
ocean with the
deeper colder layers, and vice versa.
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 Curr

Heat transfer into the
deep oceans is pretty much all mechanically
driven by «circulation» factors, so a cooling of the southern
oceans due to changes in surface winds and
currents would tend to change
deep ocean uptake.
Currents that move through the upper ocean then dive down to depth may move some of the surface heat to the deeper waters, especially where the currents have dived not just from cooling water (hot water would tend to go up, cold water would tend to go down) but because it is driven in «conveyor» systems which may run counter to expectations of where water should go when considering only local conditions, and especially, if the water is dropping because of an increase in s
