  • The long-term quantification of the Angulas Leakage is difficult due to its highly variable spatio-temporal nature and sparse observations. Here, the authors combine sea surface temperature with a series of ocean and climate model simulations to construct a 145-year long time series of Agulhas leakage.

  • Agulhas leakage increased in the 1960s through the 1980s but, despite the continued strengthening of the Southern Hemisphere westerlies, has not substantially increased in the 1990s and 2000s, according to observation- and model-based estimates.

  • Methanotrophic bacteria can consume methane emitted from the ocean floor before it reaches the atmosphere. Variations in coastal currents can reduce methane oxidation in the ocean by limiting methanotroph residence time above methane seeps.

  • An underlying assumption of palaeoceanographic proxies is that they are representative of the water properties directly above their site of deposition. Here, the authors combine high-resolution particle tracking simulations and sedimentary proxy data to challenge this assumption.

  • The Atlantic Meridional Overturning Circulation (AMOC) has a key role in the climate system. This Review documents AMOC variability since 1980, revealing periods of decadal-scale weakening and strengthening that differ between the subpolar and subtropical regions.

  • Leakage of warm, salty waters from the Indian Ocean into the Atlantic increases by up to 40 % in high-resolution numerical ocean model simulations, suggesting that low-resolution models underestimate this key part of the global meridional overturning circulation.
