Paleobiology Seminar: "Diastem Didactic: Some Recent Advances in Late Cretaceous Geochronology, Chronostratigraphy, and OAE Studies"

1:30pm to 2:30pm

Location: 

Haller Hall (Geology Museum 102)

The Geobiology/Paleobiology Seminar Series is jointly hosted by OEB and EPS

Speaker: Dr. Brad Sageman (Northwestern University)

Abstract:

In 1917, Joseph Barrell published a paper titled "Rhythms and the Measurements of Geologic Time" in which he proposed that the sedimentary record was made up of more surfaces representing missing time than rock representing recorded time....

Paleobiology Seminar: "Mesozoic Tectonics, Oceanic Anoxic Events, and the Evolution of Planktic Foraminifera"

4:00pm to 5:00pm

Location: 

Haller Haller (Geology Museum 102)

The Geobiology/Paleobiology Seminar Series is jointly hosted by OEB and EPS.  

Speaker: Dr. Mark Leckie (UMass-Amherst)

Abstract:

Global tectonics had a profound influence on climate, weathering, sea level, and seawater chemistry during Mesozoic time. The linkages between tectonic activity, planktic foraminiferal evolution and environmental...

Geobiology Seminar: "High-temperature kinetics of clumped isotopes in calcite and apatite"

2:00pm to 3:30pm

Location: 

HUCE Seminar Room

Geobiology Seminar

Speaker: Daniel Stolper (Caltech)

Abstract: The abundance of multiply substituted (‘clumped’) isotopologues (e.g., 13C16O218O2-) in carbonates is a thermodynamically controlled function of temperature for equilibrated systems. Measurement of...

Geobiology Seminar: "New insights into the formation of methane at both low and high temperatures using stable isotopes"

12:00pm to 1:30pm

Location: 

Haller Hall (Geology Museum 102)

Geobiology Seminar

Speaker: Daniel Stolper (Caltech)

Video Stream

Abstract: Methane is a critical greenhouse gas, energy resource, and product of microbial metabolisms. Despite its importance in the carbon cycle, distinguishing the sources of methane in natural...

Geobiology and Biogeochemistry

Low-temperature geochemistry enlists a wide range of traditional scientific disciplines (e.g. chemistry, biology, geology) to address questions involving Earth surface processes, modern climate studies, deep time, and many more.  At Harvard and under this heading, our department has a particular interest in the study of Earth history. Often termed Geobiology, our strengths include the study of paleontology, sedimentology, and biogeochemistry, all of which requires a truly interdisciplinary approach to science.
