Loss of Carbon from the Deep Sea Since the Last Glacial Maximum.
Science, Vol. 330, pp. 1084-1087, 19 November 2010.
DOI: 10.1126/science.1193221
Deep-ocean carbonate ion concentrations ([CO3 2-]) and carbon
isotopic ratios (d13C) place important constraints on past
redistributions of carbon in the ocean-land-atmosphere system
and hence provide clues to the causes of atmospheric CO2
concentration changes. However, existing deep-sea [CO3 2-]
reconstructions conflict with one another, complicating
paleoceanographic interpretations. Here, we present deep-sea
[CO3 2-] for five cores from the three major oceans quantified
using benthic foraminiferal boron/calcium ratios since the last
glacial period. Combined benthic d13C and [CO3 2-] results
indicate that deep-sea-released CO2 during the early deglacial
period (17.5 to 14.5 thousand years ago) was preferentially
stored in the atmosphere, whereas during the late deglacial
period (14 to 10 thousand years ago), besides contributing to
the contemporary atmospheric CO2 rise, a substantial portion
of CO2 released from oceans was absorbed by the terrestrial
biosphere.
STUDY NOTES: Benthic foraminiferal boron/calcium ratios and stable isotope data
for five cores from the three major oceans used to reconstruct
deep-sea carbonate ion [CO3 2-] since the last glacial period.
