(Formerly GEOLSCI 141 and 241) Analyzing images is a big part of day-to-day life of geoscientists, such as conducting seismic interpretation or lithofacies identification and classification. Furthermore, visual representation, recognition and feature extraction play a crucial role in providing a foundation to solve different geosciences research questions, including reconstructing depositional environment, marine ecosystem and tectonic history. Imagine analysis is often costly, time consuming and requires in-depth knowledge of specific geological sub-fields (igneous, metamorphic, sedimentary petrography, and micropaleontology). Recent improvements in machine learning techniques, in particular deep learning, have led to excellent performance in different computer vision tasks (e.g., image classification, segmentation) that significantly increase efficiency and reproducibility. In this course, we will go through the basics of machine learning for visual recognition by analyzing different real-world geoscience problems and try to understand how machine learning algorithms can be used to help solve these problems. This course is intended to provide an introduction to visual recognition with machine learning. No prior knowledge of machine learning and python programming are required.

(Formerly GEOLSCI 247) This course considers the research that has led to current architectural models of turbidite deposits as we examine diverse data sets that allow us to test these models. Intense exploration and exploitation activities by the petroleum industry have significantly advanced understanding of turbidite systems. These activities stimulated research aimed at developing predictive models of the three common turbidite reservoir types: (1) confined channel systems, (2) weakly confined channel systems, and (3) unconfined lobe systems. Each of these reservoir types are examined in detail considering recognition criteria, internal structure, reservoir characteristics, and important issues related to reservoir potential and performance. Topics of discussion include controlling processes, hierarchy, variability, uncertainty and active areas of research.

(Former GEOLSCI 248) How the petroleum system concept can be used to more systematically investigate how hydrocarbon fluid becomes an unconventional accumulation in a pod of active source rock and how this fluid moves from this pod to a conventional pool. How to identify, map, and name a petroleum system. The conventional and unconventional accumulation as well as the use of modeling.

(Formerly GEOLSCI 249) This course is a companion seminar to EPS 258 (Formerly GEOLSCI 258), in which we will explore and discuss the ambiguities of existing facies models for fluvial, eolian, and near-shore depositional environments in the pre-vegetation sedimentary record. Our goal will be to formulate new quantitative criteria for more robust paleoenvironmental interpretations of pre-vegetation sedimentary rocks. Students in the class should also enroll in EPS 258 (Formerly GEOLSCI 258) (or have attended an equivalent course).

(Formerly GEOLSCI 250) The mechanics of sediment transport and deposition and the origins of sedimentary structures and textures as applied to interpreting modern sediments and ancient rock sequences. Dimensional analysis, fluid flow, drag, boundary layers, open channel flow, particle settling, erosion, sediment transport, sediment gravity flows, soft sediment deformation, and fluid escape. Required field trip and lab section. Change of Department Name: Earth and Planetary Science (Formerly Geologic Sciences).

(Former GEOLSCI 251) Analysis of the sedimentary fill and tectonic evolution of sedimentary basins. Topics: tectonic and environmental controls on depositional systems, detrital composition, burial history, and stratigraphic architecture; synthesis of basin development through time. One weekend field trip is required. Change of Department Name: Earth & Planetary Sciences (Formerly Geological Science)

(Formerly GEOLSCI 252)Siliciclastic sediments and sedimentary rocks. Research in modern sedimentary mineralogy and petrography and the relationship between the composition and texture of sediments and their provenance, tectonic settings, and diagenetic histories. Prerequisite: 106 or equivalent or instructor approval. Required lab section. Change of Department Name: Earth and Planetary Science (Formerly Geologic Sciences).

(Formerly GEOLSCI 253) The origin and occurrence of hydrocarbons. Topics: thermal maturation history in hydrocarbon generation, significance of sedimentary, structural and tectonic setting, trapping geometries and principles of accumulation, and exploration techniques. Prerequisites: 110, 151. Recommended: GEOPHYS 223. Change of Department Name: Earth and Planetary Science (Formerly Geologic Sciences).

(Formerly GEOLSCI 254) Processes of precipitation and sedimentation of carbonate minerals as well as their post-depositional alteration with emphasis on marine systems. Topics include: geographic and bathymetric distribution of carbonates in modern and ancient oceans; genesis and environmental significance of carbonate grains and sedimentary textures; carbonate diagenesis; changes in styles of carbonate deposition through Earth history; reservoir quality and properties defined by storage capacity, flow (permeability) and connectivity of pores (effective porosity); the interplay between these properties, the original depositional characteristics of the carbonate sediments and post-depositional alteration; relationships between dissolution processes, cementation processes, and the resulting connectivity of the flow pathways. Lab exercises emphasize petrographic and rock physics analysis of carbonate rocks at scales ranging from map and outcrop to hand sample and thin section.
