Journal ArticleDOI
Suborbital-scale surface and deep water records in the subtropical North Atlantic: implications on thermohaline overturn
TL;DR: In this article, the authors reconstruct millennial-scale variations in sea surface hydrography and deep water flow in the northwestern subtropical Atlantic (Ocean Drilling Program Leg 172 Sites 1056 and 1063) with a focus on Marine Isotope Stage (MIS) 9.
Journal ArticleDOI
Millennial‐scale fluctuations in subtropical northwestern Atlantic surface ocean hydrography during the mid‐Pleistocene
TL;DR: In this paper, the authors used planktonic foraminiferal (Globigerinoides sacculifer and Neogloboquadrina dutertrei) δ18O records from subtropical North Atlantic Site 1056 to reconstruct millennial-scale changes in sea surface hydrography during marine isotope stages (MIS) 10 through 12 (∼340-440 ka).
Journal ArticleDOI
Paleoproductivity during the middle Miocene carbon isotope events: A data‐model approach
Liselotte Diester-Haass,Katharina Billups,Ingrid Jacquemin,Kay Emeis,Vincent Lefebvre,Louis François +5 more
TL;DR: In this article, the authors used benthic foraminiferal accumulation rates from three sites in the Pacific and Southern Oceans and a geochemical box model to assess relationships between the global carbon cycle and marine export productivity.
Journal ArticleDOI
Millennial-scale variability in western tropical Atlantic surface ocean hydrography during the early Pliocene
M.D. Niemitz,Katharina Billups +1 more
TL;DR: In this article, high-resolution oxygen isotope data (δ18O) from planktonic foraminifera in the western tropical Atlantic Ocean (Ocean Drilling Program Leg 154, Site 925) was used to investigate millennial-scale climate variability during an interval of relative climate warmth, the early Pliocene.
Journal ArticleDOI
Origin of millennial-scale climate signals in the subtropical North Atlantic
TL;DR: In this paper, the authors present a high-resolution planktonic foraminiferal stable isotope record (Globigerinoides ruber) spanning marine oxygen isotope stages (MISs) 6 through 8 in the northwestern subtropical Atlantic Ocean (Ocean Drilling Program Leg 172 Site 1059).
