Speaker Einat Lev, Assoc. Research Prof., Lamont-Doherty Earth Observatory Field and laboratory investigations of lava rheology Abstract Lava and magma are complex multi-phase fluids comprised of liquid silicate melt, solid crystals, and gas bubbles. The physical properties of lava depend on the interactions between these phases. Yet, despite their critical impact on conduit and flow […]

Speaker Dr. Harriet Lau, Assistant Professor, Brown University Evolving Solid Earth Dynamics as a Trigger for the Mid Pleistocene Transition Abstract Milankovitch cycles—orbital modulations in Earth’s insolation—are thought to pace ice ages over the last 2.6 million years, with dominant periods associated with changes in precession (~20,000 years) and obliquity (~40,000 years). While Milankovitch cycles […]

Applications are being accepted now through February 15, 2024, by 5 p.m. EST. Rhode Island applications are due to the Rhode Island Sea Grant (RISG) office. All applications must be submitted through the eSeaGrant web platform. RISG will be hosting three information sessions to provide information on fellowship details, accessing eSeaGrant and developing a fellowship […]

“A microfossil history from the bottom of the sea: sharks, fish, mass extinctions, and 85 million years of global change” Speaker: Dr. Elizabeth Sibert, Assistant Scientist, Woods Hole Oceanographic Institutione Abstract Fish are the most diverse group of vertebrates on the planet today, and the type and abundance of fish present in the marine ecosystem […]

“Magmatism Controls Global Oceanic Transform Fault Topography” Speaker: Dr. Xiaochuan Tian, Postdoctoral Research Fellow, Boston College Abstract Oceanic transform faults are fundamental features of plate tectonics, accommodating strike-slip motion between two adjacent mid-ocean ridge segments. The continuations of these faults form tectonically inactive fracture zones, creating the longest ‘scars’ on the Earth’s surface. Yet, despite […]

July 31, 2023 — OSEC 202, 11 a.m. Dr. Kathrin Busch, Bedford Institute of Oceanography Deep-sea coral and sponge microbiomes in an ecosystem context– key aspects, spatio-temporal predictions, management, and technology development Abstract Symbioses between microbes and invertebrates are emerging as key drivers of ecosystem health and services. Deep-sea corals and sponges can harbour dense […]

“Slow slip events in the Mexican subduction zone and their importance in the seismic cycle” Speaker: Dr. Mathilde Radiguet, ISTerre, Grenoble, France Abstract Active faults in the Earth build up tectonic stress during the interseismic period and release it in brutal earthquakes via rapid seismic slip. Improvements in earth observations over the last two decades […]
