Can a collapse of the AMOC lead to suboxic conditions?

For a couple of years The Atlantic meridional overturning circulation AMOC has been under observation. There have been examples in the past, when sudden state changes of it lead to short term and ...

Is the southern downwelling situation in the AMOC as affected by climate change as the two northern downwelling situations?

I wonder if the southern downwelling situation in the AMOC is affected by climate change as much as the two northern situations. I come to the question because I find the Cicrumantarctic circulation ...

(Why) is the thermohaline circulation not affected by the coriolis effect?

Why doesn't (e.g.) the equatorward North Atlantic Deep Water bend more to the west? Is it maybe because the water tends to move relatively slowly and the magnitude of the Coriolis effect depends on ...

Change in thermohaline circulation due to climate change

The melting of the North Polar ice masses removes a driving factor from the thermohaline circulation, known as the Gulf Stream in the North Atlantic. I wonder how much the thermohaline circulation has ...

Is CO2 in the Pacific Ocean depleted or enriched in Carbon-13 compared to the Atlantic, and why?

Due to thermohaline circulation, the Pacific water is more 'aged' so there is a higher amount of total dissolved inorganic carbon (e.g. CO2) in the deep Pacific when compared to the Atlantic. However, ...

Is the gulf stream both a wind-driven current and part of thermohaline circulation?

Currents are formed in 3 major ways: Tidal Currents Wind-driven Currents Thermohaline circulation I've seen the gulf stream mentioned as both a wind-driven surface current and being part of the ...

Thermohaline: Why is cold and dense seawater salty when warm water holds more dissolved salts?

I read that thermohaline circulation is caused by cold and saline water sinking, while warm and less dense water rises. link I understand that saline water is more dense, as there is a higher mass ...

Thermohaline Circulation in the Oceans

I'm slightly confused by how thermohaline circulation works in the Earth's oceans. Is it different for surface water as opposed to deep water? I thought that warm water from the equator is ...

Why does the meridional overturning circulation take the convoluted path that it takes?

Why does it take the very weird loop that it takes in the Pacific Ocean? And also in the Indian ocean too?

How was the atmospheric/oceanic circulation different prior to the formation of the Isthmus of Panama?

Did El Niño extend all the way to the West Coast of Africa? Did the meridional overturning circulation exist back then? Was there another overturning circulation that existed?

Does the meridional overturning circulation slow down the temperature increase from global warming?

Does it result in an increased exchange of surface heat and deepwater heat, which, in turn, help increase the amount of CO2 and heat that the deep oceans absorb? Related-On-Wikipedia: Meridional ...

How does the meridional overturning circulation affect sedimentation rates in the North Atlantic?

There's a lot of downwelling in the region. Does this increase sedimentation rates?

What causes bottom water to rise?

The water close to the deep ocean floor is called bottom water. It may be located in deep valleys or trenches. I understand that water flowing to the Arctic will sink there, because it's saltier and ...

How long does it take for the ocean conveyor to circulate?

What is the period of the thermohaline circulation in the ocean? Obviously, individual particles may take longer or shorter, but what is the average for a small water parcel to do a full loop and end ...

What was the ocean circulation like during the time of Pangaea?

So Enderton and Marshall (2009) wrote an interesting paper on the ocean circulation of various aquaplanets covered with certain terrain: e.g. an aquaplanet with a small ridge of land that ranged from ...
