To better understand these discrepancies, a recent study published in Geophysical Research Letters investigates the drivers of changes in
deep ocean circulation across a range of modern and Last Glacial Maximum (LGM, ~ 21000 years ago) climate simulations from the latest Paleoclimate Modelling Intercomparison Project (PMIP).
Presently, much of the Atlantic
Ocean is well oxygenated (Figure 1) relative to the North Indian and Pacific Oceans, where bottom water O2 concentrations are lower because of the biological removal of O2 as thermohaline circulation moves deep waters across ocean basins from the North and South Atlantic towards the North Pacific, in isolation from the surface o
