Atlantic

views updated

Atlantic Period in post-glacial times (i.e. post-Devensian or Flandrian) from about 7500 to 5000 BP which, according to pollen evidence, was warmer than the present, and moist; with oceanic climatic conditions prevailing throughout north-western Europe. It corresponds to Pollen Zone VIIa, which throughout north-western Europe is characterized by the most thermophilous (warmth-loving) species found in postglacial pollen records. The climatic optimum of the post-glacial, or current Flandrian Interglacial, is dated to the early Atlantic period. Compare BOREAL. See POLLEN ANALYSIS.
