The Rise and Fall of the Arctic Meridional Overturning Circulation (ArcMOC)
Fig. 13. from Bretones et al. (2022): Sketch summarizing the evolution of the deep mixing and the ArcMOC under the retreat of the sea ice edge. (a) During T0: 1970–80 there is deep convection on both sides of the Greenland–Scotland ridge. Both AMOC and ArcMOC are present, but the ArcMOC extent is limited by the... Continue Reading →
The East Coast’s Double Threat: Why Slower Atlantic Currents Mean Rising Seas and Less Marine Life
Figure 13 from Kim et al. (2026): Spatially averaged sea level changes (cm) from historical period (1993–2020) in (a) the northern Gulf of America, (b) West Florida shelf, (c) the South Atlantic Bight, (d) the Middle Atlantic Bight, and (e) the Gulf of Maine under the SSP-126 (blue bars), SSP-245 (cyan bars), SSP-370 (orange bars) and SSP-585 (red bars) simulations. The dynamic sea level changes are... Continue Reading →

The North Atlantic Deep Western Boundary Current is Faltering
This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Meridionally consistent decline in the observed western boundary contribution to the Atlantic Meridional Overturning Circulation” by Xing et al. (2026). Xing et al. (2026) analyzes long-term observational data from four major mooring arrays to evaluate the Atlantic Meridional Overturning Circulation (AMOC). By... Continue Reading →
Melting of the Arctic and Greenland ice sheets triggers rapid subsurface warming in the North Atlantic and Nordic Seas
This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Rapid subsurface warming in the subpolar North Atlantic from freshening" by Menviel et al. (2026). Menzviel et al. (2026) study explores how increased freshwater from melting Arctic ice and the Greenland Ice Sheet triggers rapid subsurface warming in the subpolar North Atlantic.... Continue Reading →
The Arctic’s ‘Cooling Machine’ Isn’t Broken, But Reaching Its Limit
This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Increased ocean heat transport to the central Arctic despite a well working Barents Sea Cooling Machine" by Eisner et al. (2026). This study uses the SODA4 reanalysis to examine a forty-year increase in ocean heat transport from the Barents Sea into the central Arctic. Researchers... Continue Reading →
Is Arctic Atlantification Weakening the Atlantic’s Conveyor Belt?
This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Interactions between the Arctic Mediterranean and the Atlantic Meridional Overturning Circulation: A review” by Weijer et al.
