Congratulations to Gavin Piccione for his exciting work in Terry Blackburn’s lab on the subglacial environment under the Antarctic ice sheet. Unfortunately all of his current work is strictly confidential and we can’t reveal anything here; not yet …
Madison Wood’s exciting research proposal–to reconstruct global carbon cycle perturbations using the novel stable strontium isotope proxy record measured on pelagic barite that accumulate in deep sea sediments–has been selected by the ARCS Foundation from national entries . Excellent work and well deserved. Congratulations Maddie!
Also, if you are looking for a teaser of Maddie’s work plan, listen carefully to her narrating the long-term carbon cycle …
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.
Terra Ganey will join us in the fall to work on seawater chemistry and the role it plays in the global carbon cycle. Welcome Terra, we look forward to you joining our Earth System Biogeochemistry learning community.
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.
I am looking to recruit a PhD student to work on seawater carbonate chemistry modeling and reconstruction of past changes in ocean acidity and atmospheric CO2. This project is aimed to improve our understanding of the role of the global carbon cycle in driving past climates. Please contact me for more details; general info on the UCSC graduate program in Earth and Planetary Sciences, and details on the application process.
The application deadline is January 3rd 2021 and the start date is Fall 2021.
We published a study in GRL highlighting the possibility of substantial geologic carbon release at the end of the last ice age.vv
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!
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!
Our study on the relationship between boron isotopes, pH change and CO2 climate forcing was just published in Paleoceanography and Paleoclimate.
