DOI: 10.1002/2017gl073227
Abstract: This study reconstructs a century-long South Atlantic Meridional Overturning Circulation (SAMOC) index. The reconstruction is possible due to its covariability with sea surface temperature (SST). A singular value decomposition (SVD) method is applied to the… read more here.

DOI: 10.1016/j.aosl.2021.100061
Abstract: Abstract The calculation of the meridional overturning streamfunction in the southern Indian Ocean is biased by the Indonesian Throughflow. Therefore, this study applies the vertical overturning streamfunction to diagnose the shallow overturning circulation in the… read more here.

DOI: 10.1016/j.quascirev.2020.106396
Abstract: Abstract The Global Overturning Circulation is linked to climate change on glacial-interglacial and multi-millennial timescales. The understanding of past climate-circulation links remains hindered by apparent conflicts among proxy measures of circulation. Here we reconstruct circulation… read more here.

DOI: 10.1017/qua.2018.88
Abstract: Abstract Spatially extensive and intense phytoplankton blooms observed off Iberia, in satellite pictures, are driven by significant nutrient supply by upper-ocean vertical mesoscale activity rather than by horizontal advection by coastal upwelling. Productivity of oligotrophic… read more here.

DOI: 10.1029/2019gl082110
Abstract: The meridional overturning circulation (MOC) decreases rapidly in subpolar and Nordic regions where the warm upper layer loses its buoyancy due to intense heat loss, sinks, and flows south. The major volume loss of the… read more here.

DOI: 10.1029/2019pa003818
Abstract: The Atlantic Meridional Overturning Circulation (AMOC) is thought to be relatively vigorous and stable during Interglacial periods on multimillennial (equilibrium) timescales. However, recent proxy (δ13C benthic) reconstructions suggest that higher frequency variability in deep water… read more here.
