Heidi submits her thesis and manuscript!

Despite setbacks due to COVID, our very own Heidi O’Hora submitted her masters thesis this week to graduate end-of-summer, and then turned around and submitted her manuscript to a top-tier journal for peer review and (hopefully) eventual publication in the scientific literature. Congratulations Heidi, you did it! We are so proud of the progress you’ve made over the past 2 years, especially considering it was such an unusual time.

Heidi’s thesis project involved reconstructing Late Cretaceous ocean temperatures in the modern-day region of Maastricht, the Netherlands. Her samples come from the type section of the Maastrichtian (ENCI quarry) among other locations. She found that temperatures in that area were much warmer than they are today (as expected for the greenhouse world of the Cretaceous) and that interactions between different water masses had a strong control on local ocean temperature and salinity.

Stay tuned for publication announcement later on!

SCIPP Lab welcomes 4 new group members

The SCIPP Lab/Petersen Group is very excited to welcome four new members for the coming year. Julia Kelson will arrive as a postdoc under the NSF Postdoctoral Fellowship to study paleoclimate and paleohydrology using clumped and triple oxygen isotopes, in conjunction with the IsoPaleo Lab. Two incoming Masters students, Allison Curley and Heidi O’Hora, will be working on Cretaceous paleoclimate projects. Finally, undergraduate Steve Wedel will join our ranks to work on reconstructing climate during the Last Interglacial in Turks and Caicos.
