Angela Slagle is a Research Scientist at Lamont-Doherty Earth Observatory of Columbia University. Her work focuses on petrophysical measurements as a means of characterizing sub-seafloor sediments and rocks, applied to a range of projects and geologic environments. Her current projects include studies of carbon sequestration in marine basalts (western Atlantic, Cascadia region in NW Pacific); cyclicity in physical properties as a response to Earth processes (Maldives Inner Sea); and integration of core, downhole logging, and seismic properties (various locations). Angela received a Ph.D. in Marine Geology and Geophysics from Columbia University.

Over the last ten years, she has sailed on eight research expeditions for the Integrated Ocean Drilling Program and International Ocean Discovery Program (IODP), as well as a number of research cruises on UNOLS vessels. She is also the Associate Director of the U.S. Science Support Program (USSSP) for IODP (usoceandiscovery.org).


Can Turning CO2 to Stone Help Save the Planet? | Out of Our Elements • Can we turn atmospheric carbon dioxide into stone? Spoiler Alert: carbon dioxide emissions are causing the planet to get warmer. But we may be able to use chemistry to solve this problem. Out of Our Elements hosts Caitlin Saks and Arlo Pérez Esquivel, joined by NOVA Producer Alex Clark, investigate how the planet naturally turns CO2 into stone over long periods of time, and how scientists and engineers are trying to speed up this process in hopes of capturing and storing atmospheric CO2. They’re joined by Cornell University Environmental Engineer Greeshma Gadikota, who illustrates how you can test out a small-scale form of carbon sequestration in your own home, and Lamont Doherty Earth Observatory’s Angela Slagle, who explains which places on Earth and the kinds of oceanic rocks that could play a role in scaling up CO2-to-stone transformation.
