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:

Variations in the Earth's Orbit: Pacemaker of the Ice Ages
TL;DR: It is concluded that changes in the earth's orbital geometry are the fundamental cause of the succession of Quaternary ice ages and a model of future climate based on the observed orbital-climate relationships, but ignoring anthropogenic effects, predicts that the long-term trend over the next sevem thousand years is toward extensive Northern Hemisphere glaciation.

Age dating and the orbital theory of the ice ages: Development of a high-resolution 0 to 300,000-year chronostratigraphy
Douglas G. Martinson,Nicklas G Pisias,James D. Hays,John Imbrie,Theodore C. Moore,Nicholas J Shackleton +5 more
TL;DR: Using the concept of "orbital tuning", a continuous, high-resolution deep-sea chronostratigraphy has been developed spanning the last 300,000 yr as mentioned in this paper.

Oxygen isotopes and sea level
TL;DR: In this article, the authors re-examine the data and conclude that the temperature of the abyssal ocean has been an actively varying component of the climate system, and that there has been a discrepancy between the ice volume record that these records imply and that derived from the altitude of dated coral terraces around the world.

An alternative astronomical calibration of the lower Pleistocene timescale based on ODP Site 677
TL;DR: In this paper, a modified version of the timescale proposed by Imbrieet et al. for the ODP Site 677 has been proposed, based on the precession signal in the record from ODP site 677 that provides the basis for the revised timescale.
Paleotemperature history of the Cenozoic and the initiation of Antarctic glaciation : Oxygen and carbon isotope analyses in DSDP Sites 277,279, and 281
TL;DR: An oxygen and carbon isotopic history based on analyses of benthonic and planktonic foraminifera in three overlapping subantarctic sections is presented for the last 55 m.y. as mentioned in this paper.

Late quaternary sea level: a discussion
TL;DR: A review of the position of sea level during the late Quaternary is presented in this paper, where the authors suggest a glacial interstadial and stand of sea-level at about − 8 fathoms 30,000 years ago.
