“…“There is no indication of an MOC slowdown. And the large fluctuations explain why previously it was diagnosed that a slowdown had already happened. By chance, measurements were taken at a time when the MOC happened to be quite weak.”

With the instrument array it is feasible to monitor the annual average MOC to a resolution of about 1.5 Sverdrups, or about 8 percent of the mean value. This would be sufficient to detect any large, abrupt changes in the circulation, critical to planning for future climate change.”
