Abstract

The waters off northern Iceland are subjected to extreme hydrographic variability on annual to decadal timescales. In years when cold low-salinity water moves coastward and sea ice is prevalent (i.e., the late 1960s), marine productivity of surface waters is low because the water column is well stratified. In the opposite oceanographic mode, warm, salty Atlantic Water dominates the shelf and vertical mixing results in high productivity. The AA. track these 2 contrasting modes by measuring the carbonate content of marine sediments, a proxy for productivity, in 3 cores from northern Iceland. Discussion of the results and temperature reconstructions over the last 5000 years
