Calibration of the alkenone paleotemperature index U37K′ based on core-tops from the eastern South Atlantic and the global ocean (60°N-60°S)
TL;DR: In this article, a sediment-based calibration of the U37K′ paleotemperature index is presented, based on the analysis of 149 surface sediments from the eastern South Atlantic in order to define the most suitable calibration for this region.

An introduction to organic geochemistry
Stephen Killops,Vanessa Killops +1 more
TL;DR: In this paper, the authors investigated the long-term fate of organic matter in the geosphere and its role in sedimentary organic matter preservation and degradation in the geological timescale.

Interhemispheric synchrony of the last deglaciation inferred from alkenone palaeothermometry
TL;DR: The authors applied the alkenone method of sea surface temperature reconstruction to several high-resolution sediment cores recovered from the tropical Indian Ocean between 20° N and 20° S. This finding, along with the results of recent modelling studies, provides strong support for the idea that changes in the ocean's global thermohaline circulation were not the only cause of interhemispheric climate teleconnection during the last deglaciation.

Glacial–interglacial changes in Subantarctic sea surface temperature and δ18O-water using foraminiferal Mg
TL;DR: In this article, the authors used culturing results and a core-top Neogloboquadrina pachyderma calibration to estimate glacial-interglacial changes in sea surface temperature (SST) using planktonic Mg/Ca records.

A model system approach to biological climate forcing : The example of Emiliania huxleyi
Peter Westbroek,Chris W. Brown,Judith van Bleijswijk,Colin Brownlee,Geert Jan Brummer,Maureen H. Conte,Jorun K. Egge,Emilio Fernández,Ric Jordan,Michael Knappertsbusch,Jacqueline Stefels,Marcel J.W. Veldhuis,Paul van der Wal,Jeremy R. Young +13 more
TL;DR: In this article, a single representative organism, the coccolithophore Emiliania huxleyi, is investigated in detailed interactive experimental and modelling studies, and the model system approach permits an emphasis on the non-linear character of the fluxes.

A 17,000-year glacio-eustatic sea level record: influence of glacial melting rates on the Younger Dryas event and deep-ocean circulation
TL;DR: In this paper, a global oxygen isotope record for ocean water has been calculated from the Barbados sea level curve, allowing separation of the ice volume component common to all isotope records measured in deep-sea cores.
Climatological atlas of the world ocean
TL;DR: A project to objectively analyze historical ocean temperature, salinity, oxygen, and percent oxygen saturation data for the world ocean has recently been completed at the National Oceanic and Atmospheric Administration's (NOAA) Geophysical Fluid Dynamics Laboratory, Princeton, New Jersey.
