Summary: The primary goal of this study is to assess the potential of International Ocean Discovery Program Expedition 349 Sites U1431, U1432, and U1433 for middle and late Pleistocene paleoceanographic reconstructions. For this, we recorded planktonic foraminifer abundances (tests/g of dry sediment) from the uppermost sections of Holes U1431D, U1432C, and U1433A. Our data suggest that Hole U1432C presents the highest potential for planktonic foraminifer-based paleoceanographic reconstructions. Planktonic foraminifer abundance fluctuations in sediments from Hole U1431D suggest that this hole is a good candidate to further investigate water-chemistry changes in paleoenvironmental reconstructions since the middle Pleistocene. Meanwhile, the absence planktonic foraminifers precludes the use of this proxy in reconstructions from Hole U1433A.
