Hydroclimatic variability record from the Cabo Frio coast (Rio de Janeiro, Brazil) during the last 6500 yr

This study concerns a core collected in Brejo do Espinho's lagoon from Cabo Frio littoral (Brazil) submitted to dry influence of local upwelling controlled by north-cast trade winds from the South Atlantic and particularly strengthened during El Nino events. 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.
