Late Holocene paleoclimate records from coastal regions are important for understanding long-term variability of hurricane activity. Here we present a nearly 4000-year record of severe storm landfalls and environmental changes based on organic geochemical proxies (OGPs) preserved in sediment cores from two coastal lakes in northwest Florida. Our analysis shows that there are significant variati...

Abstract Profile sampling, which causes missing or overlapping horizons, has been generally used while studying loess stratigraphy and paleoclimate. Conversely, drill sampling of thick can provide a relatively complete actual record the Quaternary climate environmental changes. Here, paleomagnetic chronological analysis particle size magnetic susceptibility analyses were performed to accurately...

Benthic foraminifera, ostracods and pteropods are reliable paleoenvironmental indicators in Quaternary deposits. However, the Ceará Basin, on Brazilian Equatorial Margin, these microfossils poorly studied. This paper investigates environmental changes during Pleistocene–Holocene transition Icaraí subbasin based micropaleontological analysis of core ANP 1011. Seventy-four taxa benthic represente...

Pollen analysis of a sediment sample obtained at 222 cm from the top of a drilling core collected in the Bay of Guanabara, Rio de Janeiro, was used as a tool to obtain more knowledge about pre-historical human living and environment. 14C datation revealed the age of 4210 years B.P. Most frequent pollen grains came from plants like Alchornea (Euphorbiaceae), Celtis (Ulmaceae), Lecythidaceae, Mel...
