Geobiology Seminar: "Illuminating sulfur isotope mass-independent fractionation (S-MIF)"

October 2, 2014

4:00PM - 5:00PM EDT

Haller Hall (Geology Museum 102)

In Person

Speaker: Andrew Whitehill (MIT) Abstract: Sulfur isotope mass-independent fractionation (S-MIF) is ubiquitous in Archean and Paleoproterozoic sedimentary rocks and provides the most convincing evidence for a low-oxygen early (pre-2.4 Ga) atmosphere. The...

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

September 11, 2014

4:00PM - 5:00PM EDT

Haler Hall (Geology Museum 102)

In Person

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...

Geobiology Seminar: "Costs, benefits and biogeography of nitrogen fixation in the ocean"

April 24, 2014

4:00PM - 5:00PM EDT

Haller Hall (Geology Museum 102)

In Person

Speaker: Dr. Mick Follows (MIT)

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

Apr 18, 2014

5:00PM EDT

Haller Hall (Geology Museum 102)

In Person

Speaker: Daniel Stolper (Caltech) Abstract: The abundance of multiply substituted (‘clumped’) isotopologues (e.g., 13C 16O 2 18O 2-) in carbonates is a thermodynamically controlled function of temperature for equilibrated systems. Measurement of clumped...

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

April 17, 2014

12:00PM - 1:30PM EDT

Haller Hall (Geology Museum 102)

In Person

Speaker: Daniel Stolper (Caltech) 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 systems is challenging...

Paleobiolory Seminar: "Sources and Sinks of Marine Biodiversity in Deep and Shallow Time"

April 10, 2014

4:00PM - 5:00PM EDT

MCZ 101 Seminar Room

In Person

Speaker: Dr. Wolfgang Kiessling (Erlangen, Germany) Abstract: Identifying regions and environmental settings in which the rates of evolution are greater or lower than average is a major quest in macroevolution. Most commonly, areas with high biodiversity...

Geobiology Seminar: "On the mechanism of sulfite reduction by the dissimilatory sulfite reductase DsrAB"

March 13, 2014

12:00PM - 1:00PM EDT

Haller Hall (Geology Museum 102)

In Person

Speaker: Dr. Ines Pereira (ITQB, Portugal) Abstract: A key reaction in microbial sulfur metabolism is the reduction of sulfite by the dissimilatory sulfite reductase, DsrAB. This enzyme is present in sulfate, thiosulfate and sulfite reducing organisms...
