In this thesis, I use data sets from four orbital robotic spacecraft missions to answer longstanding questions about the crustal structure of the Moon and the climatic history of Mars. In chapter 2, I use gravity data from the Gravity Recovery and Interior Laboratory (GRAIL) mission to constrain the quantity and location of hidden volcanic deposits on the Moon. In chapter 3, I combine GRAIL data with elevation measurements from the Lunar Orbiter Laser Altimeter (LOLA) aboard the Lunar Reconnaissance Orbiter (LRO) to investigate the nature of isostatic compensation in the lunar highlands. In chapter 4, I present a new technique for analysis of the Martian polar layered deposits (PLDs). In chapter 5, I apply that technique using images of the PLDs from the MOC and HiRISE instruments aboard the Mars Global Surveyor (MGS) and Mars Reconnaissance Orbiter (MRO) to constrain their ages and deposition rates. Thesis Supervisor: Maria T. Zuber Title: E. A. Griswold Professor of Geophysics & Vice President for Research 3 4 Acknowledgements "If you're succeeding at everything you do, you're not thinking big enough." I'm not sure if my advisor remembers giving me that piece of advice years ago, but I've thought of it frequently. Of all the people I have to thank, Maria Zuber clearly tops the list. She expects a lot from those who work for her, but those expectations are matched by a genuine faith in her students to accomplish big things. Maria is one of those people whom you try and soak up as many things as you can learn when you're the same room as her. I've heard her say before that the best thing she does is recruit the right people, but I'll politely disagree and say that the effect she has on her students through her encouragement of big ideas surpasses that. Maria is hardly the only professor that has had a large impact on me in my time at MIT. Taylor Perron has advised my work on Martian polar caps and has taught me countless lessons about science and not-science- things, and shares Maria's faith in his students to take charge of their own work and succeed. The other members of my thesis committee also deserve thanks beyond their agreement to read this document: Ben Weiss has educated me in many ways, most notably by hiring me as his teaching assistant and entrusting me with the lives of undergraduates on our field trip to the Himalayas, and Jim Head has been a figure to look up to for years and a source of advice and inspiration outside of MIT. I thank Rick Binzel for chairing my generals exam committee and for his support of my organization of our department's planetary seminar, and Lindy Elkins-Tanton for being the most influential non-advisor professor I've had at MIT by teaching me invaluable lessons about the nature of scientific research and need to be open-minded in science. I thank Walter Kiefer for inspiring my study of lunar isostasy, and the rest of the GRAIL science team for their constant feedback and inspiration. My fellow planetary science students in the department deserve special thanks. Alex Evans and Peter James have been sources of advice as the veteran students of the lab during my time here. Frank Centinello and Yodit Tewelde are close friends who have always been voices of reason. Anton Ermakov, Zhenliang Tien, and Matthieu Talpe are the younger students in the group who I jokingly have referred to as my children, but have taught me as least as much as I've taught them. Sonia Tikoo has 5 been my mentor of sorts from my first week at MIT, despite my revelation years into school that she's younger than me, and will be a fantastic scientific colleague for the remainder of my scientific career. Elizabeth Bailey was my undergraduate research assistant, will always be remembered as my first "apprentice," and undoubtedly do great things in her graduate career at Cal Tech and beyond. Jason Soderblom, Brandon Johnson, and Katarina Miljkovic have been the postdocs in my group during my time here and have always provided a useful perspective on how to graduate and take the next steps. I thank all of my family and friends and teachers from home and college, but a few people deserve special mention. My parents have provided constant support and have been surprisingly understanding as my "I'll visit Florida many times each year" slowly morphed into "I'll come home for Christmas" over the years. Christine Ryu has almost single- handedly kept me sane over the past five years, and for two people with no training in planetary science, she and Robbie Hunter came up with a pretty awesome and relevant thesis title for me in the middle of a late night cab ride in New York City. Additional people I need to thank include: Jon Grabenstatter and Morgan O'Neill for being my first close friends in the department, Phil Wolfe for being one of my best friends and roommate for more years than I'm willing to admit, Kat Thomas for her sometimes unearned constant faith in me, Roberta Allard and Margaret Lankow for bailing me out of administrative problems more times than I deserved, Javier Matamoros and Erin Koksal for their constant friendship from my first day in Boston, Arthur "Peaches" Olive and Mike Byrne for being my partners-in-crime in my EAPS class, Paul Richardson for being my lab brother, Elena Steponaitis for being a sister to me despite her UNC heritage, Cory Ip for her matzoh ball soup, Alex Toumar for her therapeutic IHOP sessions, Ben Mandler for keeping my EAPS orientation events alive, and many, many, many others who I would list explicitly if I didn't think I already was breaking a record for number of people mentioned in an acknowledgements page. 6 Table of Contents Abstract 3 Acknowledgements 5 Table of Contents 7 Chapter 1: Introduction 9 Chapter 2: Gravitational Search for Lunar Cryptomaria 13 Abstract 13 2.1.

Consid- ering processes such as sublimation and Jeans escape, we find that CO 2 ice migrates to low latitudes on geologically short (100s–1000 s of years) timescales. Crater morphology and location create a local cold trap inside Wunda, and the slopes of crater walls and a central peak explain the deposit’s annular shape. The high albedo and thermal inertia of CO 2 ice relative to regolith allows deposits 15-m-thick or greater to be stable over the age of the solar system.

  • Concentric Crater Fill on Mars
    Proceedings of the 19th Lunar and Planetary Science Conference, pp. 397-407 Copyright 1989, Lunar and Planetary Institute, Houston 397 Concentric Crater Fill on Mars: An Aeolian Alternative to Ice-rich Mass Wasting 1989LPSC...19..397Z J. R. Zimbelman Center for Earth and Planetary Studies, National Air and Space Museum, Smithsonian Institution, Washington, DC 20560 S. M. Clifford and S. H. Williams Lunar and Planetary Institute 3303 NASA Road One, Houston, TX 77058-4399 Concentric crater fill, a distinctive martian landfonn represented by a concentric pattern of surface undulations confined within a crater rim, has been intetpreted as an example of ice-enhanced regolith creep at midlatitudes ( e.g., Squyres and Carr, 1986). Theoretical constraints on the stability and mobility of ground ice limit the applicability of an ice-rich soil in effectively mobilizing downslope movement at latitudes poleward of ±30°, where concentric crater fill is observed. High-resolution images of concentric crater fill material in the Utopia Planitia region (45°N, 271°W) show it to be an eroded, multiple-layer deposit. Layering should not be preserved if the crater fill material moved by slow deformation throughout its thickness, as envisioned in the ice-enhanced creep model Multiple layers are also exposed in the plains material surrounding the craters, indicating a recurrent depositional process that was at least regional in extent. Mantling layers are observed in high-resolution images of many other locations around Mars, suggesting that deposition occurred on a global scale and was not limited to the Utopia Planitia region. We propose that an aeolian intetpretation for the origin and modification of concentric crater fill material is most consistent with morphologic and theoretical constraints.

  • Mount Mazama and Crater Lake: a Study of the Botanical and Human Responses to a Geologic Event
    AN ABSTRACT OF THE THESIS OF Robyn A. Green for the degree of Master of Arts in Interdisciplinary Studies in Geology. Botany and Plant Pathology. and Anthropology presented on June 3. 1998. Title: Mount Mazama and Crater Lake: A Study of the Botanical and Human Responses to a Geologic Event Abstract approved: / Robert J. Lillie Crater Lake, located in the southern Cascade mountains of Oregon, is the seventh deepest lake in the world. Unlike a majority of the deepest lakes in the world, found in continental rift valleys, Crater Lake is in the caldera of a volcano. For the young at heart and mind, those willing to descend (and ascend) about 700 feet to Cleetwood Cove can undertake a boat tour of Crater Lake. From the boat, Crater Lake is more than just a beautiful blue lake; it becomes the inside of a volcano, where the response of people and plants to a geologic event can be investigated. The catastrophic eruption of Mount Mazama 7,700 years ago affected both plant and human populations. Before pumice and ash from the volcano blanketed the landscape like freshly fallen snow, the forests to the east of Mount Mazama were dominated by ponderosa and lodgepole pine. Within the immediate vicinity of the volcano all life was obliterated; the force of the eruptive material toppled vegetation and buried it with ash and pumice.
