🤔 Did you know that with a weaker #AMOC tropical shallower waters got + oxygen in the last deglacial? 😱 Using benthic #forams, we explore how #AMOC influences Atlantic shallow circulation 🌊🐚🔬👩‍🚀 www.nature.com/articles/s41... @marumunibremen.bsky.social @natcomms.nature.com

It depends. Oxygen content on the ocean changes with depth but is also dependent on other physical, chemical, and biological factors. oceanexplorer.noaa.gov/facts/omz.html but in general you could say yes, the deep ocean is more oxygenated

So, in summary, we have a weak AMOC that results in a decrease in heat transport, which in turn leads to a strong temperature gradient between tropical and northmost Atlantic that accelerates subsurface circulation, bringing more oxygen to the OMZ we studied.

Winds' strength is dependent on temperature and air pressure changes, too. In fact, when you compare the differences between the tropical and northermost Atlantic sea surface temperatures, you see that these are larger with a slow AMOC 😱

In the last 27.000 years, AMOC slowdown in 2 occasions. Our oxygen reconstruction shows that there was more oxygen in those 2 occasions, meaning that the subsurface circulation was accelerated and bringing more oxygen to the OMZ 🧐

Here, we used a seafloor archive of the eastern tropical Atlantic OMZ, next to Senegal. We reconstruct oxygen changes in the last 27.000 years with benthic forams (microscopic organisms living in the seafloor & that produce a shell that fossilizes). Their distribution is sensitive to oxygen changes
July 21, 2025 at 8:10 PM
This happens in the deep ocean. In the shallower ocean, other factors like winds also drive circulation, that supply, among other things, oxygen, important for marine ecosystems. Today, areas with little oxygen exist, where subsurface circulation is lower: "Oxygen Minimum Zones or OMZs"
July 21, 2025 at 8:10 PM
It is! I will try 🧐 The ocean has different layers, each with diff. Temperature & salt content that results in density differences. These drive the thermohaline circulation that in turn drives the AMOC, a global circulation system that absorbs + redistributes carbon and heat from the atmosphere.

🥳 My 1st PhD paper was fun & challenging to write, that is why I'm grateful it received the #TopViewedArticle recognition from @wiley.com!

📖 🤓 give it a read to learn what happened to ocean heat uptake as Atlantic Meridional Overturning Circulation (AMOC) slowed down a while ago bit.ly/3EELCuq 🧵👇

I saw this cool #starterpack trend all over insta & wanted to join in 🤓 here is my #noiastarterpack version to become a cool #Micropaleontologist & look for really small fossils in earth's rocks to unravel earth's deepst secrets 🔎🔬🐚👩🏻‍🔬🌊
