Pelagic denitrification powers through
Anja Studer just found the same N isotope signature in microfossil shells before and after the termination. We think its due to the biological carbon pump. Read the full story.

35-Myr Stable Strontium
We used an inverse model to extract carbon cycle information from the novel stable strontium isotope record out of the Paytan lab, just published in Science.
Deglacial bicarbonate pulse
We published a study in GRL highlighting the possibility of substantial geologic carbon release at the end of the last ice age.vv
Surface ocean carbon
We just published a study on the distribution of carbon in the surface ocean. This work is part of Yingxu Wu’s graduate research. Well done Yingxu to get your work published!
Low ice-age polar nutrient supply
We just published a study on nitrogen isotope evidence for a significant reduction in nutrient upwelling in the Southern Ocean during the last ice age. This work is based on model development Preston Kemeny and I did as part of his undergraduate thesis at Princeton. Well done Preston to come through and get your work published!
Boron isotopes reveal climate forcing
Our study on the relationship between boron isotopes, pH change and CO2 climate forcing was just published in Paleoceanography and Paleoclimate.
Melting ice age gives silicon boost
Our paper on the impact of glacial meltwater on the ocean’s silicon inventory and isotopic composition was yes published in Nature Communications.
