Surface winds and surface ocean hydrography in the subpolar North Atlantic appear to have
been influenced by variations in solar output through the entire Holocene. The evidence
comes from a close correlation between inferred changes in production rates of the
cosmogenic nuclides carbon-14 and beryllium-10 and centennial to millennial time scale
changes in proxies of drift ice measured in deep-sea sediment cores. A solar forcing

Surface winds and surface ocean hydrography in the subpolar North Atlantic appear to have been influenced by variations in solar output through the entire Holocene. The evidence comes from a close correlation between inferred changes in production rates of the cosmogenic nuclides carbon-14 and beryllium-10 and centennial to millennial time scale changes in proxies of drift ice measured in deep-sea sediment cores. A solar forcing mechanism therefore may underlie at least the Holocene segment of the North Atlantic's “1500-year” cycle. The surface hydrographic changes may have affected production of North Atlantic Deep Water, potentially providing an additional mechanism for amplifying the solar signals and transmitting them globally.
