TLDR
The core Vema 28-238 as discussed by the authors preserves an excellent oxygen isotope and magnetic stratigraphy and is shown to contain undisturbed sediments deposited continuously through the past 870,000 yr.About:

The Relation of the Southern Trade Winds to Upwelling Processes During the Last 75,000 years
TL;DR: In this paper, the authors inferred the development of coastal upwelling and the surfacing of the Equatorial Undercurrent from radiolarian assemblages in the sediments of core V1929 (3°35′S, 83°56′W).
Journal ArticleDOI
Adaptation to global environmental change
TL;DR: In this paper, a model for climatic deviations is presented, based upon paleoclimatic experience 5,000 to 8,000 years ago, when midlatitude temperatures were 1.5 to 2.5°C higher.

New Zealand Quaternary stratigraphy: An overview
TL;DR: The first faunal evidence of cooling in New Zealand Plio/Pleistocene sequences occurs much earlier, at the base of the Nukumaruan Stage ca. 2.4 Ma, with the appearance in central New Zealand of the subantarctic taxa Chlamys delicatula and Jacquinotia edwardsii.

Decomposition of hydroxy amino acids in foraminiferal tests; kinetics, mechanism and geochronological implications
TL;DR: The diagenesis of the hydroxy amino acids serine and threonine in foraminiferal tests has been investigated in this article, where three empirical equations were derived for the disappearance of serine, and the appearance of α-amino-n-butyric acid (ABA).

Late Pleistocene paleoclimates of North America as inferred from stable isotope studies of speleothems
TL;DR: In this paper, a record of relative fluctuations in depositional temperature can be obtained from the δ 18 O variations in successive growth layers of CaCO 3 cave deposits, which reflect variations in the average annual air temperature at the surface above the cave, and therefore permit inference of past continental climate changes.

Revised carbonate-water isotopic temperature scale
TL;DR: The relationship between temperature and O(18) content relative to that for a Cretaceous belemnite of the Pee Dee formation previously reported (Epstein, Buchsbaum, Lowenstam, and Urey, 1951) has been re-determined using modified procedures for removing organic matter from shells, and is found to be 16.5 - 4.3 δ + 0.14 δ^2

Insolation changes, ice volumes, and the O18 record in deep‐sea cores
Wallace S. Broecker,Jan van Donk +1 more
TL;DR: In this article, a detailed curve of ice volume versus time is needed in order to test the validity of the hypothesis that changes in the earth's orbital parameters are the cause of oscillations in Pleistocene climate.

Oxygen Isotope Analyses and Pleistocene Temperatures Re-assessed
TL;DR: Oxygen isotope analyses of foraminiferal tests in deep-sea cores have been interpreted as showing that the temperature of seawater in the Caribbean and equatorial Atlantic varied by as much as 6°C during glacial cycles as mentioned in this paper.
Journal ArticleDOI
Carbonate-water isotopic temperature scale
TL;DR: In this article, a relationship between temperature and relative O 18 abundance in calcium carbonate in marine shells has been determined, where the relative abundance of the water in which the shell grew is known, and the temperature can be determined to an accuracy of ± 1.0°C.
