In principle, stratigraphy provides a record of past surface processes, and deciphering this is crucial to: (1) characterize the dynamics and environments of ancient landscapes; (2) understand the movement of water and sediment across planetary surfaces; and (3) quantify the response of ancient landscapes to tectonic and climatic change. However, interpreting this record can be challenging (e.g., outcrop/data/timescale limitations). This session welcomes contributions that focus on deciphering, or advancing our ability to decipher, surface processes from the stratigraphic record, and which span surface process systems on Earth and other planetary bodies. We particularly encourage contributions that tackle this challenge using multi-disciplinary approaches, including fieldwork, satellite observations, experimental work, and numerical models. Please submit your abstracts to this session using the AGU portal by August 3. We welcome submissions from early career scientists and new members of the discipline. https://bit.ly/3zlUf7A Conveners: Sinead Lyster, Victoria Fernandes, Kartikeya Sangwan, Alexander Whittaker, Safiya Alpheus [Edited for length] 5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5-5 AGU SESSION EP010: EARTH AND PLANETARY SURFACE PROCESSES GENERAL CONTRIBUTIONS We welcome contributions to this general poster session related to the disciplines, processes, and techniques involving the study of the surface of Earth or other planetary bodies. This session provides the opportunity for contributions that fall within the broad spectrum of Earth and Planetary Surface Processes. Contributions are welcome from a wide spectrum of disciplines including, but not limited to, geomorphology, sedimentology, planetary science, geophysics, engineering, atmospheric science, geology and biology. Processes of interest include, but are not limited to, fluvial, hillslope, tectonic, volcanic, glacial, coastal, marine, eolian, biologic, cryospheric and impact processes. We also welcome contributions to techniques in Earth and Planetary Surface Processes, such as field observations, numerical and physical modeling, remote sensing, geodesy, nonlinear dynamics, geochronology, geochemistry and geophysics.

Studies of the existence and state of carbonaceous material on Solar System bodies is at the forefront of planetary research. Results from studies of samples of low-albedo asteroid 162173 Ryugu from the Hayabusa2 probe are being shared and discussed. The OSIRIS-REx space probe has retrieved samples from low-albedo asteroid 101955 Bennu. As a framework for these studies, telescopic, laboratory and theoretical studies of carbon in all its forms have recently snowballed. The 2018 SSERVI Carbon in the Solar System workshop launched a series of presentations and discussions at various venues, enabling an information exchange around the weathering of carbonaceous compounds in response to thermal processes and irradiation, and what implications these compositions have for understanding material processing in the Solar System. We will generate and share ideas to support research of the new samples, along with studies of carbon, in various forms, at other locations across the Solar System. https://agu.confex.com/agu/fm22/prelim.cgi/Session/162387 7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7 AGU SESSION P013: GIANT PLANET INTERIORS New constraints to the present-day interior structure and dynamics of giant planets are critical to advance our understanding of the formation and evolution of planets in the Solar System and beyond. The Juno and Cassini missions have recently revealed key aspects of the interiors of Jupiter and Saturn from a wealth of new measurements. Further, new studies of Uranus and Neptune continue to highlight the relevance of ice giants in understanding the exoplanet population. This session will bring together theory and observations capable of advancing our understanding of giant planet interiors. We welcome submissions within a broad range of topics, including: ring and Doppler seismology, gravity fields, normal mode oscillations, zonal flows and differential rotation, dynamo magnetic fields, core detection and characterization, consequences of stable stratification, helium and heavy element bulk composition, formation scenarios, and evolutionary pathways. We highly encourage submissions from early career scientists. Please submit your abstract before August 3. Session Conveners: Benjamin Idini (Caltech), RaviT Helled (University of Zurich), Yamila Miguel (Leiden University), and Scott Bolton (SwRI) Session Chairs: Simone Marchi (SwRI), Saverio Cambioni (MIT), David A. Williams (ASU), Insoo Jun (NASA-JPL) https://agu.confex.com/agu/fm22/prelim.cgi/Session/161075 8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8-8 AGU SESSION P017: MACHINE LEARNING AND DATA SCIENCE IN PLANETARY SCIENCE Many facets of research in planetary science rely on analyzing large volumes of in-situ and spacecraft data. Traditionally, these data were collected and analyzed manually. In recent decades, developments in the field of machine learning (ML) have begun to gradually augment traditional techniques, answering the need for automatic methods that can rapidly and intelligently extract information from large datasets in a useful manner. This session will be dedicated to data driven research that leverages ML and data science to enhance our scientific understanding and return from planetary data and missions. Topics may encompass data analysis on the ground or onboard spacecraft for existing and future missions and instruments. Submissions are welcome for applications across science and engineering, including but not limited to: spacecraft operations and mission planning; surface, atmosphere, and space environment characterization; object detection and classification; change and novelty detection; interpretable methods; and other studies that apply ML and data science methods to planetary science. Please submit your abstract by August 3 at: https://agu.confex.com/agu/fm22/prelim.cgi/Session/159461 9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9-9 AGU SESSION: P023 PLANETARY ATMOSPHERES, SPACE WEATHER, AND MAGNETIC FIELDS Atmospheric retention, and how it is influenced by stellar activity (i.e., space weather) and a planet's magnetic field, is a topic of interest for Solar System and extrasolar planets. Measurements of atmospheric escape rates and processes from Solar System planets exist, with the MAVEN mission having provided detailed measurements of the erosion of Mars' atmosphere. Comparison of escape rates from Venus, Earth, and Mars has sparked debate about whether planetary magnetic fields shield atmospheres or accelerate erosion. The Kepler "radius gap" between extrasolar sub-Neptunes and super-Earths suggests that atmospheric escape can be driven by the interaction between a planet's atmosphere and its host star's space weather. We encourage submissions on all aspects of magnetic fields of Solar System planets, their interactions with the solar wind, and extensions to extrasolar planets. Please submit abstracts by August 3. https://agu.confex.com/agu/fm22/prelim.cgi/Home/0 The intent is to have a session at the American Astronomical Society 241 Meeting to focus on results from extrasolar planets.

Ultraviolet spectroscopy and imaging have a decades-long history as valuable techniques for studying atmospheres, aurorae, plumes and surface composition and volatiles on asteroids, comet nuclei and moons. While there continue to be opportunities for UV remote sensing from Earth orbit and in future robotic missions, the infrastructure for UV instrumentation is at a crossroads. Existing orbital facilities are nearing the end of their useful lives and there continue to be many phenomena that cannot be effectively studied with existing, high-heritage instrument designs. Exciting advances in UV-optimized technologies promise new capabilities that can be incorporated into the next generation of robotic probes, flexible SmallSat missions, and large aperture space-based observatories. This session welcomes abstracts covering UV science results, as well as reports on progress toward developing new technologies such as UV detectors, high performance coatings and novel sensor designs. https://agu.confex.com/agu/fm22/prelim.cgi/Session/162386 11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11-11 AGU SESSION U016: THE FORMATION AND EARLY EVOLUTION OF THE EARTH AND THE MOON You can submit an abstract by following the link: https://agu.confex.com/agu/fm22/prelim.cgi/Session/161851 This union session will be held in a hybrid format with both in-person and virtual presentations.
