| contents | Ostracodes are less common than might be normally expected at Sites 642, 643, and 644, perhaps pointing to the fact that the marine habitat below the overlying Pleistocene ice covers was a severe environment. This explanation, however, would not apply to the Pliocene and Miocene deposits from which ostracodes are just as poorly represented. In the latter case the Iceland-Faeroe Ridge might still have acted as a submerged barrier that did not allow an open ocean circulation of bottom waters. Thus the barrier presumably prevented an exchange of cold subarctic bottom water with that of the open Atlantic and therefore benthic deep-sea migration from the south was impeded. Some Quaternary species are, for the first time, recorded to extend to the Pliocene and/or Miocene. |
