For the second year, we will be discussing "Multidisciplinary perspectives on plume-plate interactions". Please consider joining us by submitting an abstract (by January 12th, 1pm CET!), or simply by putting the session in your calendar and joining the conversation. The session description can be found below, we hope to see many of you there! Multi-disciplinary perspectives on plume-plate interactions Conveners: L. Perez-Diaz, M. Arnould & M. Seton Over fifty years since the acceptance of plate tectonic theory, the driving forces behind plate motion and plate boundary formation and evolution remain incompletely understood. In addition to plate boundary forces, mantle plumes are often invoked as a trigger for processes such as continental rifting and break-up, subduction initiation, microcontinent formation and readjustments of the world-encircling mid-ocean ridge system. Moreover, the arrival of mantle plume heads at the base of the lithosphere has been invoked as the mechanism behind abrupt, short-lived changes in plate speeds and azimuths, by means of the introduction of ?plume-push? forces. However, the validity of this hypothesis has recently been put into question. In this session, we aim to bring together researchers interested in the forces driving plate tectonics, with particular emphasis on plate-plume interactions. We welcome studies that cover a range of techniques from data-driven approaches to numerical modelling or laboratory experiments, and addressing the role of mantle plumes on both modern-style plate tectonics and lithosphere behaviour in the Archean. We expect this session to include a diverse range of multi-disciplinary studies united by a common goal of understanding the dynamics of plate motions, mantle plumes and the plate-mantle system.

Meike Bagge, Maryam Yousefi, Jun'ichi Okuno, Holger Steffen and myself invite you to submit your?contribution to the EGU22?interdisciplinary session G3.3 on??Linking ice sheets, solid Earth and sea levels ??observations, analysis?and modelling of glacial isostatic adjustment (GIA)?, which is co-sponsored by the SCAR sub-committee INSTANT-EIS, Earth ? Ice ? Sea level, in view of instabilities and thresholds in Antarctica.?We will have the solicited speaker Dr Riccardo Riva, who is likely to present in person in Vienna. This session invites contributions discussing observations,?analyses, and modelling of ice sheet dynamics, solid Earth response, and the resulting global, regional and local sea-level changes and land deformation, including paleo ice sheet/sea-level studies, geodetic measurements of crustal motion and gravitational change, GIA modelling with complex Earth rheology and coupled ice-sheet/Earth modelling, future ice sheets/shelves evolution and sea-level projection. Contributions related to both polar regions and previous glaciated regions are welcomed. We also welcome contributions highlighting the effects of GIA on tectonical processes, petroleum reservoirs and?nuclear waste repositories, and the GIA contribution in natural hazard assessments.

This year's workshop is entitled Geophysics of Convergent Margins. https://protect-au.mimecast.com/s/KjnTCL7EwMfRqq7xlcBS_M4?domain=seg.org The workshop will be held in July (12-14) at the University of Washington (Seattle)." Workshop description: ===================== Convergent plate margins are important tectonic environments as these margins (1) host the largest and most destructive earthquakes and related tsunamis as well as the largest volcanic eruptions on Earth and (2) are accompanied by large onshore/offshore basins that are suitable for hydrocarbon preservation. They also represent natural laboratories to study fundamental cycles of the Earth System (e.g. carbon, water, etc.) and the fluid exchange between the Earth and the Ocean. Convergent plate margins are more challenging research environments due to their structural complexity and their dynamic evolution on short time scales. Over the last decade, the development of geophysical imaging and monitoring techniques as well as numerical and laboratory modeling have been proven useful to unravel some of the complexity of subduction zone processes. This workshop aims at expertise exchange from different fields to improve the understanding of convergent margins as multi-faceted geological systems. In particular, the steering committee is seeking presentations on the following topic areas: * Geophysical imaging and time-lapse analysis of the convergent margin system at different scales * Tectonics and geology of convergent margins (e.g. forearc basin evolution, foreland domain) * Modeling of subduction zone dynamics * Cycling of the Earth system and fluid flow at convergent margins * Natural hazards and resources * Leaders/experts on each of the topic areas have been invited to present a keynote presentation at the beginning of each session.
