Traditional geoscience departments commonly require 60 semester hours of geology and geology-related elective courses to achieve a BA/BS degree. Of the 60 hours, typically half are required courses in geology. Recently, the National Association of State Boards of Geology (ASBOG®) evaluated more...

According to recent American Geosciences Institute (AGI) workforce data, less than 11% of geoscience graduates receiving a BA/BS or MA/MS degree develop a career in academia and/or research. Given this statistic, the question then arises: How are geologists making a living upon graduation in 2019?...

Climate Science 101
Climate is the average of weather conditions over several decades.1,2 Geoscientists monitor modern climate conditions (1880 A.D. to present) in part by taking direct measurements of weather data (i.e., air temperature, rainfall and snowfall, wind speed, cloudiness, and so on)...

Introduction
Methane is the main component of almost all natural gas, and gas delivered to end-users is purified to 95-98% methane.1 There are three main sources of methane emissions from the oil and gas industry:
When a well is being drilled, cleaned out, or hydraulically fractured. As the...

Introduction
Crude oil and natural gas are complex chemical mixtures that are generally unsuitable for direct use. Oil refining and gas processing turn these mixtures into a wide range of fuels and other products while removing low-value and polluting components.
Refining and processing have both...

Introduction
Methane is the main component of natural gas, a cheap, abundant, and versatile source of energy that produces less carbon dioxide than other fossil fuels when burned. However, methane itself is a more potent greenhouse gas than carbon dioxide. Methane leaks from wells, pipelines, or...

Introduction
When oil and gas were first extracted and used on an industrial scale in the 19th century, they provided significant advantages over existing fuels: they were cleaner, easier to transport, and more versatile than coal and biomass (wood, waste, and whale oil). Diesel and gasoline...

Introduction
Geoscience – the study of the Earth – underpins our understanding of the many intersections between petroleum and the environment, from the search for resources to the study of air pollutants. Without the work of geoscientists, we would have neither the energy system nor the...

Introduction
In 2017, there were one million active oil and gas wells in the United States.1 When a well reaches the end of its productive life, or if it fails to find economic quantities of oil or gas, the well operator is required by regulators to remove all equipment and plug the well to...

Remote sensing imagery is used by researchers at the University of Wisconsin–Madison to support recovery efforts after a tornado.
Defining the Problem
Following a tornado, first responders need maps of the width and location (swath) of the damage area. The biggest challenge when integrating...
