Marine20—The Marine Radiocarbon Age Calibration Curve (0–55,000 cal BP)
Timothy J Heaton,Peter Köhler,Martin Butzin,Edouard Bard,Ron W Reimer,William E. N. Austin,Christopher Bronk Ramsey,Pieter Meiert Grootes,Konrad A Hughen,Bernd Kromer,Paula J. Reimer,Jess F. Adkins,Andrea Burke,Mea S Cook,Jesper V. Olsen,Luke C Skinner +15 more
TL;DR: Marine20 as mentioned in this paper is an update to the internationally agreed marine radiocarbon age calibration curve that provides a non-polar global-average marine record of radioccarbon from 0 −55 cal kBP and serves as a baseline for regional oceanic variation.
Journal ArticleDOI
Antarctic sea ice control on ocean circulation in present and glacial climates.
Raffaele Ferrari,Malte F. Jansen,Jess F. Adkins,Andrea Burke,Andrew L. Stewart,Andrew F. Thompson +5 more
TL;DR: This study shows that this rearrangement of deep water masses is dynamically linked to the expansion of summer sea ice around Antarctica, and may help quantify the ocean’s role in regulating atmospheric carbon dioxide on glacial–interglacial timescales.
Journal ArticleDOI
The Southern Ocean’s Role in Carbon Exchange During the Last Deglaciation
TL;DR: A 25,000-year-long record of the radiocarbon content of deep-sea corals collected from the Southern Ocean shows evidence of the 14C-depletion that must have accompanied CO2 sequestration, adding support to the existing model of deglacial CO2 dynamics.
Journal ArticleDOI
Sulfur isotopes in rivers : insights into global weathering budgets, pyrite oxidation, and the modern sulfur cycle
Andrea Burke,Andrea Burke,Theodore M. Present,Guillaume Paris,Guillaume Paris,Emily C. M. Rae,Brodie H. Sandilands,Jérôme Gaillardet,Jérôme Gaillardet,Bernhard Peucker-Ehrenbrink,Woodward W. Fischer,James W. McClelland,Robert G. M. Spencer,Britta Voss,Jess F. Adkins +14 more
TL;DR: In this paper, the authors present new δ^(34)S measurements on sulfate from more than 160 river samples from different geographical and climatic regions, and estimate that 46% of the world's freshwater flux to the ocean is accounted for in this estimate of the global riverine sulfur isotope budget.
Journal ArticleDOI
CO2 storage and release in the deep Southern Ocean on millennial to centennial timescales.

TL;DR: Analysis of deep-sea coral boron isotope data, as a proxy for pH and thus CO2 chemistry, provides evidence of CO2 storage in the deep Southern Ocean during the last ice age, and its rapid release on millennial to centennial timescales during deglaciation.
