Persistent solar influence on north Atlantic climate during the Holocene

Surface winds and surface ocean hydrography in the subpolar North Atlantic appear to have been influenced by variations in solar output through the en tire Holocene. The evidence comes from a close correlation between inferred changes in production rates of the cosmogenic nuclides carbon-14 and beryl lium-10 and centennial to millennial. time scale changes in proxies of drif t ice measured in deep-sea sediment cores. A solar forcing mechanism theref ore may underlie at least the Holocene segment of the North Atlantic's "150 0-year" cycle. The surface hydrographic changes may have affected productio n of North Atlantic Deep Water, potentially providing an additional mechani sm for amplifying the solar signals and transmitting them globally.
