Diatoms study supported by sedimentological and isotopic analyses shows dry phases infrequent before 4000 yr, a highly variable climatic phase between 3600 and 2900 yr and from 2400 yr onward a dryness enhancement. specialized holocene Brazilian coast sedimentology isotopes diatoms palaeoclimate El Nino 021 064 Comptes Rendus Geoscience 338 10 667-675 2006 1631-0713 https://www.documentation.ird.fr/hor/fdi:010035756 10.1016/j.crte.2006.05.006 1631-0713 [F B010035756] https://www.documentation.ird.fr/hor/fdi:010035756 https://www.documentation.ird.fr/intranet/publi/2006/09/010035756.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2006-10-06 2017-08-23 fdi:010035756 fre
