Prerequisites: introductory geology or the equivalent, elementary college physics and chemistry, or the instructors permission. Minerals come in dazzling colors, amazing shapes and with interesting optical effects. But mineralogy is also an essential tool for the understanding of Earth evolution. Minerals represent fundamental building blocks of the Earth system and planetary bodies. Minerals form through geological and biological processes such as igneous, metamorphic and sedimentary from high to low temperatures, from the deep interior to the Earth’s surface and related to volcanism, tectonics, weathering, climate and life. Minerals are one of our most important sources of information on such processes through Earth’s history. Minerals also represent important natural resources and are fundamental to the global economy and modern technology as we know it. In this course, we will approach mineralogy from the standpoint of earth and environmental sciences, the study of mineralogy however is of interest to many other sciences including Material Sciences, Planetology, Archeology, Biology, Chemistry and Physics with most of the 20 Nobel Prizes awarded for research involving crystals being in these last fields. The goal of this class is to (1) understand the physical and chemical properties of minerals, (2) learn techniques of mineral identification with an emphasis on optical mineralogy, (3) understand the relationship between minerals and the broader geological context.

Climate change and environmental catastrophes are on the rise, and it has been well- documented by now that those facing the heaviest impacts have largely been communities of color and / or working class. Many of these communities are also survivors of colonialism’s deeper ongoing legacies of dispossession as well as of capitalist extraction projects; yet these same communities have long had much to teach on how to be in better relations with our planet and each other. The purpose of this seminar is to train students in how to ask critical questions when it comes to the production of knowledge or when doing science.
“Community-based research” and “co-production” are increasingly popular frameworks and methods that often struggle to address the power differentials between researchers in powerful institutions and the dispossessed communities in which they work. As such, we will interrogate these concepts while simultaneously learning from several examples of decolonial research methods.
We begin by examining the colonial foundations of the sciences, with a special focus on the geo- and climate sciences. The ideological underpinnings of these sciences assume the earth to be an inert object ripe for exploitation; this legacy of European modernity is often at odds with the worldviews of indigenous peoples and their relations with nature. We then explore several anti-colonial and critical science scholars’ works and ask: what would it mean to revisit the foundations of our disciplines with a decolonial lens? How do we know (study) and relate to a place in a non-extractive and mutually respectful way that centers local communities and indigenous knowledge and practices? We will explore this through several examples, including an in-depth dive into this seminar’s ongoing collaborative community project with The Black School, a New Orleans based community organization facing lead contamination on their land within the context of a long legacy of environmental racism.
Students taking the seminar for 3 credits and who aim to decolonize their own research will be trained in ethnographic methods by developing an anthropological lens - first through a self-ethnography workshop that focuses on the positionality and then through their own mini-ethnography projects.
The goal of this course is to help students improve their writing for journal publication. Topics will include strategies for constructing an article; for keeping the manuscript moving forward; and for improving the quality of the student’s writing. Students must be actively working on a manuscript for publication, and must be willing to commit to a minimum of 10 minutes of writing per day. Additional work will include short reading and writing assignments throughout the term, and a small number of peer-review sessions outside of class. The course will be discussion oriented and taught in seminar style and will meet once per week for 1.5 hrs.
This seminar will cover the fundamentals of the theory of ice-sheet dynamics. While the focus will be on viscous ice-sheet flow, we will cover heat flow, basal sliding, hydrology more briefly later in the semester.
We will start from first-principles and introduce all the key concepts needed to build an ice flow model, including stress, strain, rheology, vector calculus, tensors, stress balance, mass conservation. We will use these concepts to derive the simplest possible ice flow models (e.g., assuming perfectly plastic rheology, the shallow ice approximation) and build in complexity from there. We will use these models to build intuition for the first-order dynamics of ice sheets, by examining them analytically and numerically where appropriate. We will use a similar approach for the other topics later in the semester.
As well as a better understanding of ice-sheet dynamics, our aim will be to introduce students to mathematical modelling, demonstrating the overall approach, key concepts will nondimensionalization, and the power of simple models for understanding how natural systems work. We will also aim to build proper intuition for what partial differential equations and solutions to them really are.
Many of these topics could be useful in areas outside glaciology and anyone interested is encouraged to join us.
