GiGGLES (Graduates in Geosciences Getting Lunch and Explaining Science) is a weekly lunch talk that provides an opportunity for graduate students to practice a talk or presentation for an upcoming conference or class project, or to work on public speaking skills.
Earth’s mantle has been oxidized compared to its cosmochemical building blocks since the earliest Hadean. This oxidation is linked to Earth’s initial differentiation, including processes in magma oceans, but these remain poorly understood. During its subsequent evolution to the present, Earth has developed a substantial oxidized surface reservoir that amounts to approximately 20% of the oxidative power of the accessible Earth, with the other 80% remaining in the mantle. This surface reservoir is essential to the modern surface environment, but...

GSPD (Graduate Student Postdoc seminar) is a weekly lunch talk that provides an opportunity for graduate students and postdocs to get constructive feedback from peers, to practice giving presentations in preparation for the job market or other opportunities, and to better understand what fellow students and postdocs are working on.

Hurricanes are a major disturbance to tropical forests. We used census observations at Bisley Experimental Watersheds (BEW) in Puerto Rico to study the mortality after hurricane Hugo in 1989 and after hurricane Maria in 2017 and the subsequent recovery of the forest after hurricane Hugo between 1989 and 2014 (the last census before hurricane Maria). We found that hurricane-induced mortality varied with species/plant functional types (PFTs) and stem sizes. Specifically, palms had the lowest mortality, followed by mid and late...

Earthquake Insights From the Best Recorded Volcanic Caldera Collapse In History
Two outstanding problems in seismology are predicting the recurrence times of earthquakes and understanding the physical processes that immediately precede them. While geodetic measurements record elastic strain accumulation, most faults have recurrence intervals far longer than available measurements. Foreshocks provide the principal observations of processes prior to mainshocks, yet variability between sequences has limited generalizations of pre-failure behavior. In 2018 Kilauea volcano...
