Shuning’s 17O leaf water study from Mpala Kenya is now published in EPSL. Congratulations Shuning! This makes a nice contribution to the growing datasets of 17O variation in continental waters.

EARTH 467 students headed to southwestern Ohio last weekend to check out some Silurian outcrops. We managed to find some section, fossils and even dry weather.

Emily Beverly has joined the group as a postdoctoral fellow. She’ll be working on triple oxygen isotopes in soils and paleosols.

As of last week, there are now two newly minted PhDs from the Hopkins stable isotope group: Dr. Sophie Lehmann and Dr. Huanting Hu.

The combination of their PhD theses represents a huge advance in our understanding of triple oxygen isotope distributions in animals, among other things (e.g. South African paleoclimate and pCO2 in the Cretaceous!).

Sophie Lehmann 
Thesis Title: “Studies of Carbon, Oxygen and Strontium Isotopes in Tooth Enamel: Evaluating Paleoenvironmental Change in South Africa and Expanding the Paleoclimate Tool Kit”
advisor: Naomi Levin
next stop: postdoc at University of Pittsburgh

Huanting Hu
Thesis Title: “Triple Oxygen Isotopes of Biominerals: A New Proxy for Reconstructing Paleoaridity, Paleoecophysiology and Paleocarbon-Cycling”
advisor: Ben Passey
next stop: postdoc at Rice University

Nice work Sophie and Huanting!
