About the GP3 Laboratory

Our lab takes an interdisciplinary approach to investigate a broad range of questions relating to Earth’s atmosphere and ocean in the past, the role of dust in the climate system, processes impacting marine sediment accumulation and transport, and the interaction between surficial geology and regional climate. Specifically, we use a suite of geochemical methods and tracers, with a particular focus on noble gas mass spectrometry and the distribution of major, trace and rare-earth elements applied to a variety of archives that span the Cenozoic. Combining these techniques with models of the Earth system, we address questions such as:

• How do atmospheric and ocean circulation respond to warmer-than-present climate states?

• Can we accurately characterize the scale and distribution of atmospheric aerosols in the past, and if so, what are the driving mechanisms and downstream impacts?

• How can we better constrain the accumulation of material in the deep sea, and what are the related impacts on our ability to reconstruct past environments?

• What can we learn about early animal domestication and use-of-space from combining geochemistry and archaeology?
