Late Pliocene changes in the North Atlantic Current
B. David A. Naafs,B. David A. Naafs,Ruediger Stein,Jens Hefter,Nabil Khélifi,Stijn De Schepper,Gerald H. Haug,Gerald H. Haug +7 more
TL;DR: In this paper, an alkenone biomarker was used to reconstruct the sea surface temperature and surface water productivity at Integrated Ocean Drilling Project (IODP) Expedition 306 Site U1313 during the late Pliocene and early Pleistocene, 3.68-2.45 million years ago.
Journal ArticleDOI
Variations in mid-latitude North Atlantic surface water properties during the mid-Brunhes (MIS 9–14) and their implications for the thermohaline circulation
Antje H L Voelker,Teresa Rodrigues,Katharina Billups,Delia W Oppo,Jerry F. McManus,Jerry F. McManus,Ruediger Stein,Jens Hefter,Joan O. Grimalt +8 more
TL;DR: In this paper, stable isotope and ice-rafted debris records from three core sites in the mid-latitude North Atlantic (IODP Site U1313, MD01-2446, MD03-2699) are combined with records of ODP Sites 1056/1058 and 980 to reconstruct hydrographic conditions during the middle Pleistocene spanning Marine Isotope Stages (MIS) 9−14 (300-540 ka).
Journal ArticleDOI
Strengthening of North American dust sources during the late Pliocene (2.7 Ma)
B. David A. Naafs,B. David A. Naafs,Jens Hefter,Gary D Acton,Gerald H. Haug,Gerald H. Haug,Alfredo Martínez-García,Alfredo Martínez-García,Richard D. Pancost,Ruediger Stein +9 more
TL;DR: In this paper, the authors present orbitally-resolved records of terrestrial higher plant leaf wax input to the North Atlantic over the last 3.5 million years, based on the accumulation of long-chain nalkanes and n-alkanl-1-ols at IODP Site U1313.
Journal ArticleDOI
Millennial-scale ice rafting events and Hudson Strait Heinrich(-like) Events during the late Pliocene and Pleistocene: a review
TL;DR: In this paper, the authors review the occurrence and origin of millennial ice-rafting events in the North Atlantic during the late Pliocene and early Pleistocene (last 3.4 Ma) with a special focus on North Atlantic Hudson Strait (HS) Heinrich(-like) Events.
Journal ArticleDOI
Variability of surface water characteristics and Heinrich-like events in the Pleistocene midlatitude North Atlantic Ocean: Biomarker and XRD records from IODP Site U1313 (MIS 16-9)
Ruediger Stein,Jens Hefter,Jens Grützner,Antje H L Voelker,B. David A. Naafs,B. David A. Naafs +5 more
TL;DR: In this paper, a reconstruction of Milankovitch to millennial-scale variability of sea surface temperature (SST) and sea surface productivity in the Pleistocene midlatitude North Atlantic Ocean (MIS) 16-9) and its relationship to ice sheet instability was carried out on sediments from Integrated Ocean Drilling Program (IODP) Site U1313.
