The oxygen isotopic composition of seawater during the Last Glacial Maximum
High-resolution oxygen and hydrogen isotope measurements were made on pore fluids from deep-sea sediments from sites in the North and South Atlantic. The data provide direct measurements of changesExpand
El Niño/Southern Oscillation and tropical Pacific climate during the last millennium
Fossil-coral oxygen isotopic records from Palmyra Island are splice together to provide 30–150-year windows of tropical Pacific climate variability within the last 1,100 years, implying that the majority of ENSO variability over the last millennium may have arisen from dynamics internal to the ENSo system itself.

Changes in the mode of Southern Ocean circulation over the last glacial cycle revealed by foraminiferal stable isotopic variability
Benthic foraminiferal oxygen and carbon isotopic records from Southern Ocean sediment cores show that during the last glacial period, the South Atlantic sector of the deep Southern Ocean filled toExpand
Origin of Global Meltwater Pulses
The fact that frequencies measured in climate records are the same as those predicted by the astronomical theory of climate change is undisputed (Hays, Imbrie & Shackleton 1976). However, theExpand
Pleistocene vertical carbon isotope and carbonate gradients in the South Atlantic sector of the Southern Ocean
[1] We demonstrate that the carbon isotopic signal of mid-depth waters evolved differently from deep waters in the South Atlantic sector of the Southern Ocean during the Pleistocene. Deep sitesExpand
Climate connections between the hemisphere revealed by deep sea sediment core/ice core correlations
Abstract Correlation of Southern Ocean deep sea sediment core records with ice core records of polar climate delineates with unprecedented detail the relationship between high latitude climate andExpand
Interaction Between the ENSO and the Asian Monsoon in a Coral Record of Tropical Climate
The oxygen isotopic composition of a banded coral from the western equatorial Indian Ocean provides a 150-year-long history of the relation between the El Nino–Southern Oscillation (ENSO) phenomenonExpand
Abrupt Cooling of Antarctic Surface Waters and Sea Ice Expansion in the South Atlantic Sector of the Southern Ocean at 5000 cal yr B.P.
Abstract Antarctic surface waters were warm and ice free between 10,000 and 5000 cal yr B.P., as judged from ice-rafted debris and microfossils in a piston core at 53°S in the South Atlantic. ThisExpand
Evaluating climate indices and their geochemical proxies measured in corals
Abstract. Standard ocean/climate indices such as the Niño-3 sea surface temperature (SST) index, based on sparse instrumental data, and atmospheric indices such as the Southern Oscillation IndexExpand
Late Pleistocene evolution of the ocean’s carbonate system
Abstract We demonstrate that the carbonate record from a single site (Ocean Drilling Program Site 1089) in the deep South Atlantic represents a qualitative, high-resolution record of the temporalExpand
