Subtropical iceberg scours and meltwater routing in the deglacial western North Atlantic
Abrupt centennial-to-millennial shifts inNorthernHemisphere climate during the last deglaciation are thought to have been triggered by the discharge of large volumes of meltwater and icebergs to the subpolar North Atlantic1. Here we show that meltwater and icebergswere also transporteddirectly from the Laurentide icemargin to the subtropicalNorthAtlantic in a narrow coastal current. We present ...
متن کاملHydrography of chromophoric dissolved organic matter in the North Atlantic
The distribution and optical absorption characteristics of chromophoric dissolved organic matter (CDOM) were systematically investigated along three meridional transects in the North Atlantic Ocean and Caribbean Sea conducted as part of the 2003 US CLIVAR/CO2 Repeat Hydrography survey. Hydrographic transects covered in aggregate a latitudinal range of 51 to 621 north along longitudes 201W (line...
متن کاملNorth Pacific and North Atlantic sea-surface temperature variability during the Holocene
Holocene climate variability is investigated in the North Pacific and North Atlantic realms, using alkenone-derived sea-surface temperature (SST) records as well as a millennial scale simulation with a coupled atmosphere-ocean general circulation model (AOGCM). The alkenone SST data indicate a temperature increase over almost the entire North Pacific from 7 cal kyr BP to the present. A dipole p...
متن کاملDeglacial Indian monsoon failure and North Atlantic stadials linked by Indian Ocean surface cooling
The Indian monsoon, the largest monsoon system on Earth, responds to remote climatic forcings, including temperature changes in the North Atlantic1,2. The monsoon was weak during two cool periods that punctuated the last deglaciation— HeinrichStadial 1 and theYoungerDryas. It hasbeensuggested that sea surface cooling in the IndianOceanwas the critical link between these North Atlantic stadials ...
متن کاملPersistent 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 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-...
