TL;DR: A carbonate accumulation record that covers the past 53 million years from a depth transect in the equatorial Pacific Ocean is presented and large superimposed fluctuations in carbonate compensation depth are found during the middle and late Eocene.
Journal ArticleDOI
Changes in sea-surface conditions in the Equatorial Pacific during the middle Miocene–Pliocene as inferred from coccolith geochemistry
Gabrielle Rousselle,Catherine Beltran,Marie-Alexandrine Sicre,Isabella Raffi,Marc de Rafélis +4 more
TL;DR: In this paper, a new alkenone-derived Sea Surface Temperature (SST) record and δ18ONoelaerhabdaceae data of the 2-5μm carbonate fractions from the IODP site U1338 located in the Eastern Equatorial Pacific (EEP), over the Miocene-Pliocene.

TL;DR: The Pacific Equatorial Age Transect (PEAT) as discussed by the authors was designed to recover a continuous Cenozoic record of the equatorial Pacific by coring above the paleoposition of the Equator at successive crustal ages on the Pacific plate.
Journal ArticleDOI
Coccolith δ18O and alkenone records in middle Pliocene orbitally controlled deposits: High‐frequency temperature and salinity variations of sea surface water
Catherine Beltran,Marc de Rafélis,Fabrice Minoletti,Maurice Renard,Marie-Alexandrine Sicre,Ullah Ezat +5 more
TL;DR: In this article, the authors used a granulometric separation technique to concentrate coccoliths in monospecific fractions, and then measured the isotopic signatures (δ18O and δ13C) and alkenone unsaturation ratio on the same recorder: Pseudoemiliana lacunosa.
Journal ArticleDOI
Multiproxy approach for determination of nature and origin of carbonate micro-particles so-called “micarb” in pelagic sediments
TL;DR: In this paper, the authors used a granulometric separation method of the main carbonate particles to characterize and quantify the compositions of the carbonate phases of the sediments and give access to the geochemical signatures (oxygen and carbon stable isotopes) and mineralogical characteristics of each type of carbonate particle.
