A recent decline in North Atlantic subtropical mode water formation

Nature Climate Change, Published online: 23 March 2020; doi:10.1038/s41558-020-0722-3

Over 60 years of hydrographic data from southeast of Bermuda show the temporal variability of North Atlantic subtropical mode water. Between 2010 and 2018, there was an 86–93% loss of thickness, suggesting weaker production of mode water that is expected to continue with warming.
