This summer has seen very low sea surface temperature anomalies in the North Atlantic.

Using animations of these over the last year I feel the runoff of freshwater from Hudson Bay, into the Labrador current, and in turn into the Gulf Stream component of the AMOC, has been a cause of the disruption of heat transfer to the North Atlantic Drift.

Would this be correct? Has the runoff into Hudson Bay increased since September last year compared to a 10 year average?

  • $\begingroup$ Thanks Aabaakawad. I am specifically interested in the mechanics of how the Labrador currents interacts with the gulf stream, and if this relates to the 25% contribution of freshwater to the sub-polar arctic that is Hudson Bay runoff $\endgroup$ – acidohm Nov 8 '15 at 7:26
  • $\begingroup$ For example, labrador current is very cold but this time of year I doubt this us Greenland melt, yet hudson bay is also anomalously cold $\endgroup$ – acidohm Nov 8 '15 at 7:34
