UTIG Seminar Series: Peter Driscoll, Carnegie Institution for ScienceSeptember, 26 2025Time: 10:30 AM - 11:30 AMLocation: PRC 196/ROC 1.603 Speaker: Peter Driscoll, Scientist, Earth & Planets Laboratory, Carnegie Institution for Science Host: Doug Hemingway Title: The Lifecycle of Planetary Magnetic Fields Abstract: Planetary magnetic fields offer the first barrier between atmospheres and the solar wind, and are expected to play a central role in long-term habitability. In this talk we discuss why planetary magnetic fields are important to planetary habitability and how they change over billions of years of planetary evolution. We discuss the ubiquity of planetary magnetic fields in the Solar System and the prospects for detecting exoplanet magnetic fields. We review the requirements for magnetic field generation by dynamo action, general limits to thermal dynamo action, and how the planetary cooling rate affects magnetic field evolution. We will highlight how Earth’s magnetic field has evolved over the last 2 billion years, and how paleomagnetism and dynamo theory can be used in tandem to infer the dynamical evolution of the deep interior. |

Seismic Imaging of the Queen Charlotte plate boundary Abstract: The formation of new subduction zones is critical for plate tectonics, but detailed records of subduction initiation are scarce. Obliquely convergent ocean-continent transform plate convergence may be one of the most favorable environments for subduction initiation due to their pre-existing weak zone and significant contrast in lithospheric properties, but there are few locales of this nature that can be observationally studied. The transform Queen Charlotte plate boundary (QCPB) separates the North American and Pacific offshore western British Columbia and southeastern Alaska, connecting the Cascadia and Alaska subduction zones. The QCPB accommodates up to 55 mm/yr of plate motion, mostly along the strike-slip Queen Charlotte Fault, but up to 15° of oblique convergence occurs in its southern segment, offshore Haida Gwaii, BC. A coincident sedimentary wedge (the Queen Charlotte Terrace), a 2012 M7.8 tsunamigenic thrust earthquake, and seismological indications of a dipping slab has led many investigators to consider this southern segment a subduction zone, but the region lacks many of the other defining characteristics. A paucity of crustal scale seismic imaging along the plate boundary has left the structure and behavior of the system uncertain. In this talk I will use multichannel seismic reflection profiles acquired in 2021 to constrain crustal structure along the southern segment of the QCPB. This dataset reveals the accommodation mechanisms of oblique convergence and is used to classify this segment as an incipient subduction zone, settling a decades long-debate over the nature of the plate boundary. As an incipient subduction zone, the southern QCPB provides crucial observations of early deformation and the structural evolution that occurs during subduction initiation. Motivated by the 2012 M7.8 earthquake and the potential for future events, I will also use this seismic dataset to estimate the thermal structure of the plate boundary through an analysis of bottom simulating reflectors, better informing future hazard analysis of the region. |

UTIG Seminar Series: Kelly Nunez Ocasio, Texas A&MOctober, 10 2025Time: 10:30 AM - 11:30 AMLocation: PRC 196/ROC 1.603 Speaker: Kelly Nunez Ocasio, Assistant Professor, Department of Atmospheric Sciences, Texas A&M University Host: Danielle Touma Title: Novel Regional Modeling Approaches for Current and Future Tropical Weather and Climate Abstract: Africa’s weather–climate system, including the African Easterly Jet (AEJ) and West African Monsoon, strongly influences high-impact weather across Africa and the tropical Atlantic. However, how this system responds to climate warming remains unclear due to limitations in global climate models. We address this using convection-permitting simulations with MPAS-A and a pseudo-global warming approach. Results show a northward-shifting and intensifying AEJ under mid-century warming, alongside increased monsoonal moisture. These changes alter the intensity and location of mesoscale convective systems (MCSs) and African Easterly Waves (AEWs), which can seed Atlantic tropical cyclones and cause significant impacts. In the second part of the talk, I turn to Mesoamerica and the Caribbean—regions with complex hydroclimates and sparse observations. I will introduce the Mesoamerica Affinity Group (MAAG), an NSF NCAR-supported initiative promoting collaborative, high-resolution climate research. A key project includes a two-week convection-permitting MPAS-A simulation of Hurricane Maria (2017), using a variable-resolution mesh (15–3 km). Preliminary validation shows strong performance in simulating precipitation, the ITCZ, and low-level jets. This dataset, now publicly available via NCAR’s Research Data Archive, supports broader analysis of tropical cyclones and extreme rainfall events. At Texas A&M, my group continues to explore how tropical systems across Africa, the Atlantic, Central America, and the Caribbean are evolving in a warmer, moisture-rich climate. |
