Prof. Sasha Wagner, aboard the Alvin research submersible, sends a bit of “explosive” news from the East Pacific Rise:
In our history of the understanding of plate tectonics as a unifying theory for how the earth functions, there has never been a direct observation of volcanism along the mid-ocean rise. This is as close as we’ve come and is a huge deal!
Univ of Delaware's press release: https://www.udel.edu/udaily/2025/may/rare-tica-deep-ocean-volcanic-eruption/
Students in Prof. Morgan Schaller's Oceanography class were able to interview Prof. Wagner on ship live from the classroom during her two recent research cruises, all in real time. This has been a great opportunity for the students to be engaged in the research and think critically about it.
Top-Cited Article:
Prof. Frank Spear's work entitled "Pressure-temperature evolution of the basement and cover sequences on los, Greece: Evidence for subduction of the Hercynian basement" has been recognized as a Top Cited Article in Journal of Metamorphic Geology.
Presentation Award:
Grad student Alex Collins received the Outstanding Student Presentation Award for his presentation entitled "Dams and reservoirs alter the transport and storage of organic matter within the Upper Hudson Watershed" at the AGU Annual Meeting last December. This honor is awarded for only the most exceptional presentations during AGU24 and Alex received $100 as designated by his section, Biogeosciences.
