Nannoliths content of MIRA-CP1 core, Portugal

Sixteen calcareous nannoplankton taxa and didemnid ascidian spicules were identified throughout MIRA-CP1 core (see Alday et al. 2006 for further details). On the basis of calcareous nannofossil (calcareous nannoplankton and ascidian spicules) assemblages, defined in terms of presence, species abundance, diversity and dominance, the MIRA-CP1 core (ca. 25 m thick) was spreviously divided into five different nannofossil zones 6 (NNZ).
