  • Two major meltwater events are documented in cores from the NW Labrador Sea. These meltwater events coincide with Heinrich (H) layers 1 and 2 from North Atlantic sediments. The AA. hypothesize that δ18O records from these sites close to the former
  • ice margin should indicate the largest depletion due to meltwater of all North Atlantic sites.

  • climate in the North Atlantic region by controlling variable fluxes of icebergs and meltwater, as well as meltwater routing.

  • Deep-sea paleoclimatic records show that the Quaternary climate around Iceland was, and probably still is, very sensitive to rapid shifts in North Atlantic oceanic circulation. Correlations between six rock sequences in western, northern, eastern

  • Monthly zonal indices (ZI:s) from January 1899 to August 1992 in a North Atlantic area (40°W-5°W) and a north European area (5°E-40°E) are analysed. Time series analysis show that the ZI:s for each area does not show the same evolutionary trends
  • and that any distinct periods are hard to identify, except for a phase with low ZI for winters over the North Atlantic area during 1955-70. The correlation between ZI and temperature is shown to vary over time (especially for spring and autumn) indicating

  • The AA. present the most important thermal features of Europe's climate, stemming from its location in moderate latitude in the vicinity of Atlantic Ocean and from the sculpture of its earth's surface. Dependence of the air temperature from latitude

  • The Banyoles lacustrine sequence shows that the vegetational history of the northeastern Iberian Peninsula during the last 30 000 yr follows the North Atlantic pattern of climatic oscillations. This high-resolution record contains well-preserved
