The University of California, Santa Barbara (UCSB) was awarded a $157,133 Project Grant under the National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) to conduct collaborative research on the interactions between the Ontong Java Plateau and the Samoan/Rarotonga mantle plumes. The project will sample seamounts on top of the Ontong Java Plateau to study how the passage of this large volcanic structure impacted the volcanism of the Samoan and Rarotonga hotspots approximately 60-30 million years ago. The research aims to determine if the Ontong Java Plateau's thick lithosphere suppressed the degree of melting in these hotspots, resulting in more enriched mantle signatures. The 43-day seagoing expedition will involve early-career scientists, graduate students, and undergraduates, with plans to lead public outreach activities in port. The project period runs from July 1, 2024 to June 30, 2027.
