The biodiversity of deep-sea ecosystems is closely linked to orbital and suborbital climate
changes during the late Quaternary as documented by the diversity and species …

Abstract The Australia/New Zealand region of the Southern Ocean is influenced by several
of the major global water masses of the oceans and is the prime entry point for cold deep …

Unlike the familiar Phanerozoic history of life, evolution during the earlier and much longer
Precambrian segment of geological time centred on prokaryotic microbes. Because such …

The nitrogen-isotope record preserved in Southern Ocean sediments, along with several
geochemical tracers for the settling fluxes of biogenic matter, reveals patterns of past nutrient …

A range of complementary radionuclide proxies in sediments of the southernmost Atlantic
Ocean over the past 140,000 years indicate that glacial periods were characterized by …

The fractionation of silicon isotopes by three species of marine diatoms, Skeletonema
costatum, Thalassiosira weissflogii, and Thalassiosira sp., grown in batch culture, is …

Laboratory culturing experiments with living Globigerina bulloides indicate that Mg/Ca is
primarily a function of seawater temperature and suggest that Mg/Ca of fossil specimens is …

We report nitrogen isotope data for nitrate from transects of hydrocast and surface samples
collected in the eastern Indian and Pacific sectors of the Southern Ocean, focusing here on …

Marine radiocarbon (14C) dates are widely used for dating oceanic events and as tracers of
ocean circulation, essential components for understanding ocean–climate interactions. Past …

Boron/calcium ratios were measured in four benthic foraminiferal species (three calcitic:
Cibicidoides wuellerstorfi, Cibicidoides mundulus, and Uvigerina spp., and one aragonitic …
