Pollen distribution and stable oxygen isotope record of foraminifera from ODP sites 175-1082 and 175-1083
A late Pliocene high-resolution pollen record from the southeast Atlantic (Ocean Drilling Program Site 1082) registers vegetation development in southwest Africa. The marine record is continuous, ranges from 3.5 to 1.7 Ma, and has a millennial resolution between 2.9 and 1.9 Ma. Changes in climate an...
