"Changes in the vigour of the Nordic Overflows over the last 3000 years."

Abstract:

The Nordic Overflows are the densest waters of the deep limb of the Atlantic Meridional Overturning Circulation. Changes in the vigour of these overflows may have had important climatic effects in the past and possibly in the future. Yet, evidence for multidecadal to millennial changes in the deep limb of the AMOC and their potential relationship to North Atlantic climate variability during our current interglacial is still scarce. During this talk I will present grain size data (a current speed proxy) from sub to decadally resolved sediment cores located in the direct pathway of the two Nordic Overflows (east and west of Iceland) spanning the last 3000 years. The results will be discussed in relation to centennial and millennial climate variability in the North Atlantic region.
